To improve the sense of 3D, animations are usually rendered of several MIP frames in which the viewpoint is slightly changed from one to the other, thus creating the illusion of rotation. This helps the viewer's perception to find the relative 3D positions of the object components.
The use of multiple interlaced frames (MIP) and viewpoint shifts is employed to create a sense of depth and movement in 3D animations. This technique helps viewers perceive the spatial relationships between objects within the animation.
