Designing 3D animations is like having control of a complete studio. As well as simulating three-dimensional shapes step by step by defining points, lines and surfaces, the artists also have to consider the "camera" angle and changes in lighting, to create a three-dimensional scene on the two-dimensional computer screen.
有趣的是，設計三Ｄ，就等於操控一座攝影棚，美術師除了勾勒出點、線、面，一步步模擬出立體模型外，還要考慮鏡頭的角度、光影的變化，從無到有，在平面螢幕中幻化出一個立體場景。
