The deep (Z-Buffer) variations may produce numerous effects, characteristics of 3D. Here for example the intersection of the face with the modulated face.

Z-buffer is also a source of animations, we used it for example in the film "naturellement" where a forest is constituted with trees which begin walking through the others.By keeping an image with its deep map, we had a kind of 3D palette : we used it for example to increase the thickness of certain "gardens".

The deep (Z-Buffer) variations may produce numerous effects, characteristics of 3D. Here for example the intersection of the face with one modulated face.
