# [3D] Gaia’s Ikebana: Two 3D Sketch Models

### Week 5’s lesson

When I first heard that we are going to explore curvilinear volumes for this assignment, my mind simply went blank. Straight lines are difficult enough for me, and now I have to work with curves? This is going to be a huge challenge…

Anyway, we learned how to sculpt curvilinear volumes such as the sphere, cylinder, and cone out of foam during Week 5’s lesson. The process looked really complicated and I honestly thought that I was doomed because I had trouble visualising how to cut the foam blocks into shape. However, after trying to sculpt them first-hand, it was actually not as difficult as I had imagined! The cylinder was straight-forward and I did not have any trouble with it. The sphere was not difficult to sculpt, but it was definitely tedious since I had to ensure that I sand the block evenly, or else the sphere would be out of shape. The one that I had most trouble with was the cone. I followed the instructions on how to cut the cone but somehow cutting a cylinder out instead. Therefore I simply used another simpler but more tedious method of cutting eventually.

Here are the final products!

### Two 3D Sketch Models

One thing I knew for sure was that I wanted the cone to be the dominant in my sketch models. I find the shape of the cone intriguing since we hardly see this shape around actually! The only times I see cones are the safety cones by the roadside, party hats, and ice cream cones. Hence, I want the cone to take the spotlight this time.

Sketch model 1:

Dimensions

Cone (D): H 12cm, R 1.5cm

Sphere (SD): R 2cm

Cylinder (SO): H 9cm, R 0.25cm

• Radius of D and SD are similar. The difference can be bigger
• SO can afford to be skinner since it stands out and competes with D and SD.

Sketch model 2:

Dimensions

Cone (D): H 27cm, R 2cm

Sphere (SD): R 1.5cm

Cylinder (SO): H 19.5cm, R 0.25cm
