The Start 

Before I dive into my final project, I will be sharing why and how it came to be.

I started this course with a simple assignment of “reflecting an example of generative art that I found interesting” and one of the examples I chance upon was Patrick Huebner “Generative Physics System”. What amazed me was the autonomous particle interactions. Furthermore, the development of this project was coded and compiled using Processing.

Generative Physics Systems

 

This example shows me the interlink of programming and art, and what we can achieve if we are to combine these two elements. Therefore, I decided that Processing will be my choice of medium.

Exploratory Process

 

For my first project, exploratory sketch, I wanted to depict the movement of the non-linear and unpredictability element of fish movements. I explored and did research on the behaviours of fishes and used the particle system in Processing to simulate the flocking movement of fishes based on a simple set of algorithm rules.

 

 

 

 

 

Basic Mechanism

 

Exploratory Sketch: Movement with Neurons

Pushing the project further, I tweaked the behaviour of the particles to be less constrained and create room for the particles to make mistakes by detaching themselves from the flock. As a result, instead of one group of flocking particles, now there are multiple groups of particles. Moreover,  I improved the visual aesthetics and immersive experience of the art yet still retaining the generative element.

Final Project Process

After my first project, I felt that I have a better understanding of particle systems in Processing, and I wanted to take a step further by developing something new. One of the generative artworks introduced during the second week of class was William Anastasi, Subway Drawing.

Key takeaway: Simple generative system yet producing a surprising result. (Applying this methodology to the basic mechanism of the code)

 

 

The Aim

My aim was to translate his analogue generative artwork into a digital piece. Therefore, I observed his methodology and created my own autonomous line drawing particle in a 3D space. Additionally, in this artwork, the audience is able to control the perspective of the sketch and observe the illusion of different elements and nuances that were not seen in the previous viewpoint. In other words, every angle in the generative sketch will showcase a new form of abstract drawing.

 

First Iteration

Referencing from Casey Reas Path, the first iteration of the project focused on the basic mechanism, which is the fluid path movement of the lines.

 

Result

The first blocking of the code aims to create a visually dynamic moving line using Processing’s particle system. As the particles move around the canvas, they leave a trail of lines. The behaviour of the particle was created with references to my exploratory sketch, with less complicated characteristics and solely focusing on the fluid movement of the line.

 

Next part of the code aims to create the abstract mechanism. The idea is to create an abstract drawing based on the movement of the particles. Therefore, I extended the length of the lines, and if the lines reach a certain length, it will fade away to prevent an overload of lines.

 

Abstract Perception

The final iteration of the project focused on the visuals of the lines. I implemented different colours that are applied to each of the line groups. Additionally, tweaking the alpha channel, a subtle mixing of colours appears when the lines of different colours are aligned with each other.

 

Live Demo

Further Development

To push the idea of “Abstract Perception” or “Movement with Neurons” further, both of these artworks can be translated to Virtual Reality technology using the software, Unity. In this context, it can provide a richer immersive experience and the audience can experience the artwork with all of their senses.

A Framework for Understanding Generative Art

In this article, Dorin, McCabe, McCormack, Monro & Whitelaw posits that a framework for the description, analysis and comparison of generative artworks is needed. The authors argued that in order to theorise about generative art effectively, there is a need to have a framework that is uniquely suited to the description and analysis of generative art’s core, which is the dynamic processes employed by the artist. This framework aims to address the gap in generative art theory by inviting critical and creative literacy in generative systems.

Why a need for the framework?

Before diving into the framework, it is essential first to understand why there is a need for a framework.

The authors contend that discussion around art involves frameworks, even if the artwork meanings are implicit. Common discussed elements of art involve “a language-based description of the work, the media, date of execution and the work’s possible meanings”. However, such approaches to art discussion do not capture the essence of process-based works, which prevents further and more affluent comparisons. Therefore, there is a need for an applicable framework for generative art to accommodate the wide variation of process-based works. For instance, both Cornelius Cardew’s The Great Learning, Paragraph 7 and Casey Reas Process 18 are a work that is classified as generative art. Yet both of the artwork’s medium and experience are different. Thus, it would be difficult to compare them without any framework.

 

Cornelius Cardew’s The Great Learning, Paragraph 7

Cardew’s Paragraph 7 is a self-organising choral work. It involves singing, humming and speaking a fixed sequence of words and phrases. According to the instructions, the singers are given control over their interpretation of the instruction. In each line of the instruction, it indicates a new word or phrase and is repeated a different number of times and at different amplitude levels, as indicated in the score. Members of the choir choose a new pitch for each new line, by matching neighbour pitches and only introduce unheard pitch when no new pitch can be found or sung from the existing group of pitches.

 

Casey Reas’ Process 18

Reas’ Process 18 is a software-based line drawing system that generates a digital image for printing. It specifies how a set of lines can be moved across a plane, and, when they touch, be joined to create quadrilaterals of varying opacity.

 

A closer look at both of these artworks reveals an underlying factor that made them both similar, the generative processes. Hence, a framework allows for a conversation to discuss a broad range of generative pieces more consistently. Furthermore, it may also reveal unnoticed similarities and associations between different generative pieces. Therefore to address the argument of theorising generative art effectively, the author introduced a framework that is divided into descriptions of four main properties that constitute a generative art system: entities, processes, environmental interaction and sensory outcomes.

Understanding the Framework’s Properties

Entities refer to the subject involved in a generative process. It could be physical, chemical, biological or mechanical. Entities play a vital role in the generative process in the perceived outcome of a generative artwork. For instance, a computational generative process often involves an agent-based system, which simulates the actions and interaction of autonomous agents, whereby entities are identical, but their individual behavioural patterns are different. An example of my last sketch, “Movement with Neurons”, each of the particles is an entity that demonstrates some characteristic, distinguished by their unique behaviours.

 

Processes refer to the “mechanisms of change that occur within a generative system”; which involves the operation that influences entities behaviour. It can be described as conditions or events that trigger a particular entity behaviour or cause a chain reaction (domino effect) to the entities. These include the initial conditions ( the state of the entities before the process begins) or initialisation procedures (the actions or conditions necessary to start the process). However, the processes of a generative work may or may not be explicit to the audience.

 

Environmental interaction refers to the broader environment from which the generative systems draw information or input upon which to act. The inputs could be from the physical world or through devices that detect human interaction. For generative works, the outputs of the generative system will influence subsequent inputs. It can also involve the artist and the work interactions, especially for generative art, the creator will often tweak the parameters of the system based on ongoing observation and evaluation of its outputs resulting in changes to the outcome.

 

Sensory Outcomes simply refers to the outcomes of the generative work, that arise directly from the interaction of the processes and entity. The interaction between the process and entity can be either perceptible or imperceptible. For instance, in Cardew’s Paragraph 7, the audience is able to directly witness the entities (singers) as they enact the singing process. This system is described as flat, whereby the entities and outcomes occupy a single perceptible layer.

 

However, for computational works, the processes and entity interactions are not immediately apparent and usually take place behind the scenes during the development of the generative systems. Such systems will be labelled as natural mapping, whereby the structure of entities, process and outcomes are closely aligned. Both of these examples share a similar process, yet their physical manifestations and aesthetic experiences are different. Therefore, to appreciate the outcome of the generative works is to understand the intangible and hidden elements that give rise to the perceived outcomes.

 

Demonstrating the Framework

Having illustrated the framework properties, the authors’ also made references to different generative examples from diverse mediums and demonstrates how the framework can make a meaningful comparison between a wide variety of generative systems from different periods. It should be noted that this framework is intended to supplement rather than supersede existing critical approaches.

Limitations & Future Creative Uses

While the proposed descriptive framework provides a summary of the essential components in a generative system, it does not discuss the aspect of the artistic motivations. Instead, the framework is focused on the implementation and mechanics of a generative system. Nevertheless, this framework can allow an alternative view to make reasonable and effective critics and comparison of various generative works in terms of the processes involved. Indeed, the framework has provided a methodology to make a clear connection of generative works that were previously difficult to articulate.

 

Hence, utilising this framework, I can compare and contrast similarities and differences to appreciate the process that the artist made in its creation. Likewise, the unpacking of the generative process, I am also able to make use of the different generative traits found in the framework to expand my creativity for future generative systems.

Second Iteration

For the second iteration, I was focused on improving the visuals of the lines and made two significant changes.

  1. Implement different colour for different groups of lines.
  2. Increased visual width of the lines, when the lines are viewed closer.

Implementation of Different Colours

Lesson from my exploratory sketch, the colours in this project will not be changing continuously to avoid confusion. However, colouration will be statically applied to be distinct to all members of each line group. I explored with different colours and chose colours that contrast well with a white background.

Colours: Red, Yellow-Orange & Grey-Blue

 

Colours Mixing 

Additionally, based on the audience’s viewpoint, there is also a subtle colour mixing when the lines of different colours are aligned with each other. Nonetheless, the colour mixing was not made explicit to the audience, because I prefer such nuances to be discovered through the audience’s perspectives and remind them that there is always more to learn in this art.

Example of colour mixing

There is a green line in the sketch (left side) created not by code, but through an overlay of two different lines.

 

Video Example

 

Width of The Lines

For the next implementation, I took Prof Dejan advice on increasing the width of the lines when it is viewed in close up (zoomed in). Initially, I had some problems implementing the code using Processing’s mouseWheel() function because the way the function works and the data produced from scrolling was not suitable for my project. Hence, I came up with a simple solution of modifying the strokeWeight() based on the camera distance calculation, which is controlled by scrolling. I will be showcasing this during the live demo.

Live Demo 

Further Progress

For my next iteration, I will be attempting to implement a function whereby when the audience moves around “something” happens. However, I have not yet think what that “something” could be because I do not want to complicate the essence of this sketch; therefore, this will be an idea on hold first.

Lines and Interpretations,

Final Project Idea:

The final project aims to create a digital abstract line drawing in a 3D space. Additionally, the audience is able to control their perspective and observe the illusion of different elements and nuances that were not seen in the previous viewpoint.

First Iteration

For the first iteration, I will be focusing on the basic mechanism of the system. There will be two parts of the basic mechanisms:

  1. Create a fluid path movement similar to Casey Reas’ Path
  2. Translate the logic of William Anastasi’s Subway Drawing generative system into the code

The First Block of the Code: The Path system

The first blocking of the code aims to create a visually dynamic moving line using Processing’s particle system. As the particles move around the canvas, they leave a trail of lines. The behaviour of the particle was created with references to my exploratory sketch, with less complicated characteristics and solely focusing on the fluid movement of the line.

Outcome

 

The Second Part of the Code: Inserting the Abstract

Next part of the code aims to create the abstract mechanism. The idea is to create an abstract drawing based on the movement of the particles. Therefore, I extended the length of the lines, and if the lines reach a certain length, it will fade away to prevent an overload of lines.

 

 

Outcome

 

 

The illusion

The generative art was designed to allow the audience to view the abstract path in 3D; therefore, at every different angle, the audience will see a new perspective and meaning of the art. This will be better illustrated in a live demo.

Different Colours to the Lines?

ABSTRACT01.JS, MARIUS WATZ

For my next iteration, I will be exploring the implementation of different colours to different groups of lines, and examine how the colour combinations can play off one another, and in turn how they can influence the viewers.

New Idea | Brain Storming Phase

For my final project, I will be creating a new sketch but using the lessons from my exploratory sketch. Before developing a sketch, I will look at what has already been created and understand their methodology and the process behind the art piece and not just the final outcome of the work. Next, I will block out the basic mechanisms of the code in my head, before actually writing and executing the code. Hence, for this week I will just be solely focusing on the conceptualization process of my final project.

Process Inspirations

William Anastasi, Subway Drawing

One of the artworks that inspired me was “Subway Drawing” not because of his abstract drawing, however his methodology of building a simple with a set of simple rules yet producing such a surprising result. I always tried to create and structure my code based on real-life examples, so this could be one of the methodologies to apply for my basic mechanism.

Key takeaway: Simple system yet producing a surprising result. (Applying this methodology to the basic mechanism of the code)

Casey Reas, Path

A sketch by Casey Reas, who is also the co-founder of Processing. “Path” creates a very smooth flowing of lines, that may look a simple piece of artwork to the audience, yet behind the scenes requires complicated coding to develop such an aesthetic experience.

Programming nowadays serves as a mathematical expression, but also as an aesthetic experience.

Concept Idea for Final Project

For my final project, I will continue to use Processing as my medium. Drawing the idea of abstract drawing and trail from both of these artists, I will be creating an abstract path drawing using processing. What distinct my idea from both of the artists is the ability to translate this abstract path drawing into 3D. Referencing from my past exploratory sketch experience, I will be using a similar particle system; however, with a new set of behaviour and characteristics (Number of lines, Speed of the lines, size, the separation between each line)

Element of Surprise 

 

The element of surprise comes from the experiences and interpretation of the viewer. The viewing of the abstract paths can change completely depending on the angle from which the audience views it. As such, at every different angle of the 3D abstract path, it will display a new meaning to the artwork based on our unconscious visual bias. For instance, the position of the photographer, the angle of the sun and the formation of the clouds can make all the difference in a landscape shot. Hence, the audience will see different elements and notice nuances that one single perspective cannot accommodate.

 

This is still a work in progress idea but I believe this idea will be more apparent once the basic mechanism of the sketch is completed. 

Time Frame

This will be the draft project schedule, to ensure that I keep track of my progress.

Week 8 – Conceptualise

Week 9 – Basic mechanism of the sketch

Week 10-12  – Sketch Improvements

Week 13 – Presentation of Final Project

Movement with Neurons

A quick recap of my sketch, I wanted to depict the movement of the non-linear and unpredictability element of fish movements. To make my idea possible, I used processing as my medium.

Research

 

I started by exploring the various behaviours and movements of the fishes influenced by their neurons’ connectivity. I felt that it is essential first to acquire the understanding of the fish mechanisms and the nature that comes along with it before I could start to digitalise it using processing. Besides that, I also explored various artist’s works to be inspired, especially on artwork that was created digitally.

 

Guiding Reference

Mandelbrot Fractal (1979) by Benoit Mandelbrot

One of the artworks that inspired me was Mandelbrot Fractal (1979) by Benoit Mandelbrot, which was one of the first computer graphics to display fractal geometric images using a computer algorithm. What it does is using a mathematical formula to create endless repeating patterns of aesthetic properties. This was something similar to my sketch idea, so I always referred to his methodology as guiding points throughout my experimentation with processing.

 

First iteration (Basic Mechanism)

I started with the basic mechanics that simulate the patterns of a flocking fish. The first iteration was solely focused on the basic mechanism of flocking behaviours using particles simulation. As this was the foundational block of the sketch, I felt that the rules have to be written in a simple manner such that my future self will be able to understand and make changes to the parameters easily.

 

The basic rules/behaviour of the algorithm was created simplistically with only three actions.

  • B1. Alignment: follow the heading of a local particle
  • B2. Cohesion: Move towards the average position of a local particle
  • B3. Separation: Avoid crowding local particle

Sketch

Critic

While the basic mechanism was achieved, I felt that it was too rigid. It did not have this perception of chaos and order. My rules were constraining the particle, such that there was less room for a mistake to occur, and to me, that was not generative enough.

 

Second Iteration (Order & Disorder)

For my second iteration, I focused on blending order and disorder to mimic the patterns similar to the biological life of fishes in the ocean. I looked upon some examples made using Unity and found a work that I could relate on back to my sketch. 

https://blogs.unity3d.com/2020/03/09/crossing-into-the-4th-dimension-how-carl-emil-carlsen-creates-generative-art-with-unity/

Constrains

I tried to create something similar; however, I was constrained with the number of particles I can produce due to hardware limitations. Nonetheless, I still managed to tweak the particle behaviour to reflect something like the example.

 

Further Tweaks

Additionally, I took Professor Dejan suggestion and made further tweaks to the properties of the particles, to portray a more reactive and natural form of particle behaviour. Now the particles are less constrained, and it creates room for the particles to make mistakes. Furthermore, instead of one group of flocking fish, now there are multiple groups of fishes. However, it still lacks that visual aesthetic touch and immersive experience.

Sketch

 

Third Iteration (Aesthetics & Immersive)

My last iteration of the sketch was focused more on the visual aesthetics and immersive enhancement. One of the artworks that intrigued me was Artist Refik Anadol. I felt that his artwork was mesmerizing and something that I am inspired to achieve.

 

Melting Memories

Further Tweaks

I explored the different variation of colours that can be used to complement the sketch, and I decided to implement a system that could change the colour of the particles over time. Furthermore, I have also ramped up the particle count to 2,500 (it was quite demanding for my computer). To add a final touch, I switched my sketch from 2D to 3D. 

Sketch

 

Strong & Weak Aspects of The Finished Work

Weak Aspects

There were two stumbling blocks that I felt restricted in my explorative sketch. First, I was limited by my computer processing capabilities. As much as I want to render 100,000 particles simulation to create a visually appealing artwork like Artist Refik Anadol, I couldn’t expand my sketch beyond what my computer is capable of producing. Perhaps is the lack of understanding of how processing works behind the scene, such as how the algorithm is processed. 

 

Next, I couldn’t achieve some suggestion by Prof, as I was limited to the library functions in Processing. One of the suggestions was to create a “predator” particle that could influence the dynamic of the particle’s behaviour. 

However, I could not create the “predator” particle due to frequent crash when I tried to generate two separate particle systems (One for normal fish, Another for Predator). 

 

Strong Aspects

The finalised work was less rigid and dull as compared to the first iteration, in terms of aesthetics and randomness. There was an evolution in terms of the behaviour of the particles; the algorithm is now optimised for particles to make mistakes and in a sense, make the particle appear alive and natural. Also, the system is built such that countless possible variations can be produced with just a tweak to the parameters of the code.

 

What I have learned in the process.

Ironically, I learnt that generative art is neither programming nor art. Generative art is the meeting point between the two disciplines; it’s the discipline of taking logical, systematic and rigid processes and subverting them into illogical, unpredictable and expressive results.

 

Therefore, I have learnt to remove this logical thinking that I had previously, to be more flexible with my ideas and exploration. Throughout the process, I also learnt to explore with various artworks, and just be inspired and open-minded to different works on the internet. Most importantly, incorporate the different ideas by the various artists into my sketch.

 

Everything else that was important.

During the guest talk by Professor Vladimir Todorovic, I raised the question with regards to finding the fine line between abstract and concrete, and he mentioned that there is ‘no perfect fine line between abstract and concrete’. I tried to relate this to my exploratory sketch process to understand what he meant.

 

Indeed, the process has shown me that order and chaos, simplicity and complexity, abstract and concrete aren’t necessarily the opposite ends of a spectrum. They can be easily intertwined. However, at the same time, we have to be careful not to stray too far into one spectrum or the other. Thus, I find that it is crucial to find this balance when we are creating generative pieces.

 

A Possible Generative Sketch Idea

 

Moving forward, I would like to explore further the use of particle movement to create abstract drawings, similar to William Anastasi’s subway drawings.

The article, Amplifying The Uncanny, by Broad, Leymarie and Grierson offered an insightful knowledge of how machine learning algorithms can be optimised and used to produce uncanny results.

 

Machine Learning & Generative Adversarial Network

Machine learning is a system where pattern data are used to predict future data or other outcomes of interest. It is understood as an automated process of optimisation, where an algorithm processes data and finds a set of parameters that best ‘solve’ a pre-defined objective function. DeepFake, a software that produces images that can trick the human eye into believing that they are real; it utilises machine learning, in particular, the Generative Adversarial Networks (GAN) framework to produce a sample of realistic images.

 

Next Great Movement in Art or Zombie Art?

Generative Adversarial Networks have then been widely used in the production of art and is seen as the next great movement in art. However, it has also received several critiques. Firstly, the production of new artworks by the dataset of existing artworks is seen as dull and obvious as Hassine and Ziv called it the “Zombie art”. Another criticism is that generative artwork relies too heavily on deep neural networks to produce mesmerising samples, without any meaningful framing of the works being presented by the artist.

 

Argument

Perhaps, the reason why Hassine and Ziv label generative art as “zombie art” is the problem of how it is very difficult to value generativity. One can’t see at a glance whether it took time or skill to create, similar to photography, one may think is just a press of a button to produce art as compared to paintings or sculptures which are seen to require more work. Nonetheless, from the experience in making my first sketch, generative art is definitely not just a press of a button and it does require creativity in the process.

Next, even though machines are heavily relied upon to automate some aspect of the generativity, it does not mean that it is not significant or meaningful as compared to other fields of art. Rather, I argue that it is actually a new form of creative outlet that artist could utilise in producing art pieces.

 

“Being Foiled” & the Uncanny experience.

Expanding on GAN, one of the explored artworks in this paper was “Being foiled”, which reverses the outcome of DeepFake algorithms. Instead of producing images that look imperceptibly realistic, “Being foiled” invert this objective, by optimising the system to generate what it sees as being fake and turning the image into complete abstraction. As a result, it amplifies the uncanny nature of these machine hallucinations.

                                                           

The ‘Uncanny‘ is referred to as a psychological or aesthetic experience that can be characterised as observing something familiar that is encountered in an unsettling way. The uncanny effect is usually seen in objects that have a likeness of human qualities, whereby it is close to human-like but not human; as a result, it becomes creepy. For instance, a robot that looks very similar to a human, which invokes familiarity yet an uncomfortable feeling.

 

                                                           

The author illustrated his point of uncanniness by picking an iteration of the model whereby the uncanniness is potentially most amplified. Indeed, just by viewing the sample, it does provoke a feeling of uncanniness. It is familiar, yet it gives a sense of unease. Relating this to generative art criticism as dull or monotonous repetitions, “Being foiled” actually shows us how generativity can invoke human perceptions and feelings. In this context, it provokes a sense of uncanniness to the audience. 

 

Hence, the question is, how can we incorporate intangible emotions into our sketch that can be understood visually and consequently make generative art less banal?

Sketch Exploration/Changes

 

Reactive Trails

I have modified the particle trails to be more reactive based on its speed. For example, particles that are moving slower will have a shorter trail; particles that are moving fast will have a longer trail.


Initial Appearance of the Sketch

The initial sequence of the sketch is modified, whereby particles will “explode” with some particles leaving outside the sketch window, and slowly transit to the various school of fishes. I aim to create a perception of chaos at the start, whereby it slowly transits to groups of fishes. The live demo will better illustrate my point.

 

 

Different Species

I have included different variations of particle behaviours. The particles create their group, but there are also instances whereby the particle moves alone. Particles may also eventually leave their group to join another group or proceed as an individual particle.

Small changes

  • Particles now can leave outside the sketch window
  • Particles have different generated behaviour based on the rules of the algorithm
    • E.g. Speed, groups, separation, etc.

Challenge

Introducing a “predator” to a school of single species to influence the shape dynamics.

  • I tried to introduce a “predator” as suggested by Prof Dejan, but somehow my code always crashes whenever I introduce a new particle system with a distinct set of behaviours. I am assuming that the library of the code only allows one particle system, and I may have to find other alternatives to create the “predator”.

Next Iteration

  • Will be exploring on incorporating colours into the particles
  • Add a background music
  • Will explore 3D Geometrics for the particles (hopefully it doesn’t crash)

Particle Prototype

Quick Exploration

To begin understanding how to move particles,  I did a quick research on the 3 properties that are commonly used to control particles simulation.

  • Alignment: steer toward the average heading of local flockmates
  • Cohesion: steer to move toward the average position of local flockmates
  • Separation: steer to avoid crowding local flockmates

The intention is to simulate the rhythm and harmonic movement of a fish, to give my viewers a sense of oneness (unity) in their mind.

Prototyping & Testing

 

With the basic knowledge of the 3 properties, I used a physic library in processing to formulate the behaviour of the particles. In the beginning, there were some errors with the physics system whereby the particles are not constrained (anchor) to each other. This was quickly solved by constraining the particle into a “sphere”.

 

Further tweaks

After the particle mechanism is much more stable, I introduced more particles into the system. I have also added “trails” behind the particle, for aesthetic purpose. Every time the code is executed, a different result will be displayed. Perhaps, further, improvement will be to add colours? Flashing lights? Calming background music using minim?

Closed Systems: Generative Art and Software Abstraction

By Marius Watz, 2010

 

With the rise of computational technology, art is going through an evolving process with the combination of the principles of unpredictability and the purity of logic as Marius Watz describes it.

 

In his paper, Watz touches on the notion of exploiting the complexity produced by a computation that could not be made by human hands. He elucidates that generativity is a useful strategy that allows the author to harness the power of a computer to generate an infinite series of possible outcomes. However, to perform such a process, the author requires technical skills to be able to understand computer code and perform reverse engineering to achieve a desirable outcome. Therefore, as Watz contends, generative art requires both technical skills and aesthetic intuition for the artist to be able to express their art through the manipulation of computation. This resonates with me, as someone who sees through the lens of both art and programming, as both are vital ingredients to produce an interesting computational generative artwork. Moreover, to a certain extent, computational skill is an art because it requires critical thinking and ingenuity to create objects of beauty.

 

On the other hand, computational aesthetics also has its constraint. As pointed out by Watz, simulation is spontaneous and organic, which can only be replicated by computers with the explicit encoding of how the data is processed and even the most experienced programmer will encounter unexpected results or errors. Nonetheless, programming error can lead to discoveries and new learnings. Indeed, as a programmer that is still learning, more often than not, I gained valuable information from errors. For that reason, I see mistakes and errors as a beneficial process of discovery, learning and improvement.

 

Besides that, Watz also made a comparison with interactive art and generative art. He elaborates by drawing a distinct difference between generative art and interactive art. Generative art operates based on an autonomous system with infinite outcomes based on the algorithms, while interactive art utilises a feedback loop of interaction between a system and its users. Based on this definition, I do see the distinct differences and mutual exclusiveness in their respective art forms. The way I see it, both arts require controllability through a set of rules. In generative art, the algorithmic rules create art, and for interactive art, the rules of human interaction create art.

 

Beyond that, Watz has also postulated that generative art has reached a level apart from computation means. While Watz has embraced the complexity of computer systems, he does agree that generative art is not about the computer itself and would be a mistake to think that generativity is only capable of being expressed in pixels. Thus, generative art can come in many possible outputs, and I certainly do agree and believe we should expand and explore our creativity of generativity in many various possible outputs, and not just limit our observations of generativity to solely one medium.
