SUMMARY
This article is provided to give you a brief explanation of when Adaptive Supersampling and Displacement Mapping are performed.

To begin with, the two processes are completely separate operations.

- Displacement mapping occurs when the surfaces are subdivided (preprocessing before rendering ever starts). Vertices are displaced along the object normals. This is independent of object scaling, etc.

- Adaptive supersampling takes place between the rays that are fired out from the camera during rendering.
