Object

For the 1st 3D lesson the class was told to bring an object that was interesting to them. I brought a set of house keys with a key chain attached to it, but I realised that they weren’t as good as an example to explain the Dominant (D), Sub dominant (SD) and Subordinate (SO).

The dominant, would be the whole key, the sub dominant would be the white area while the subordinate would be the image of the koala bear. The whole object was almost of the same colour, sliver, and the entire surface is shiny, which causes the difference among the 3 groups to be not as obvious. If the D was much more bigger and the SO was much smaller with a different colour, it would have made it a better example for the exercise.  

So I tried to find another example at my hostel, it is not a perfect and best example but it would be better than the keys.  which is a red swiss knife.

The D is the sliver portion as it covers the most area for the swiss knife, while the SD is the red portion as it smaller than the metallic part, and the SO is the golden O symbol. The swiss knife has more colours to differentiate the 3 groups as compared to the keys. However, it would much better if the D is much more bigger compared to the SD while the SO should be smaller.

Front view

The SO had the same thickness as the SD and the height was too tall. Hence, I cut down on the height such that it is 1/3 of the breadth of the SD annotated with a X and made the SO extremely thin. 

Side view

The SD is too long and is too similar to the height of D. Hence, I shorten the SD and lengthen D such that SD is 1/3 of D as annotated with L.

Front view

The length of SD is too long as compared to the breadth of D, hence I shorten SD and made D wider in order to achieve a 2:3 ratio for SD’s length and D’s breadth. In addition, I wanted to make changes to the model and wedge the SO to the SD as indicated in the diagram.

Side view

SO is too long and thick as compared to SD, hence I removed a huge area of the SO. I tried to make SO as thin as possible so that it is 1/3 to the breadth of SD annotated as A. The breadth of D is similar to A as well, thus I decided to extend it. As for additional changes, I wanted to pierce SO through D which is why there was an extension to the left of D

Front view

SD too short as compared to D and SO is too long. After the SD extends down more, the SO will shift down such that the placement is 1/3 of the SD. In addition, the SO will be adjusted such that it will pierce through the SD

Top view

SD was shortened as its length is the same as the width of D, hence it was reduced such that SD’s length is 2/3 of the width of D indicated as x. 

 

Overall I prefer Model #3 as compared to the other 2 as it will be much easier to work on *cough cough* and it gives a more interesting figure. I will be working more on this as the final model for submission.
