Though there are varying shapes  within the parameters of artistic and technical design, for me, there are two dominant shapes in 3D Computer Animation Technology namely organic and artificial shapes.  Usually, when we talk about artificial shapes, these are forms that are man-made.  While organic shapes are forms created by nature through a process called natural evolution as understood in the context of natural selection.

3D Computer Animation, in terms of technological scope, has the propensity to develop and manage artificial shapes compared to natural or organic shapes. Let say for example the arcs in a series of waves, the ability to simulate such natural occurrence in the virtual space is still being develop as a function of technology with the hope that the movement will be natural and at the same time organic in its behavior.

In the 3D computer animated feature 'Nemo", one can notice that the movements of the body of waters featured in the said feature are functions of creative license and space. In other words, there are a lot of development space in terms of making "water movement" more natural as much as possible.  But then again, movement is dependent on  the material's approach to reality.

Nevertheless, still, at the moment, the development and management of  softwares that will deploy natural shapes minus the glitches is still a "technological holy grail". The articles that I recently read suggest that software developers are consisitent and determined to perfect 3D computer animation deployment with the urgent need to deploy far more realistic organic shapes like the human form.
