Working with the adaptive subdivision engine

“

- The adaptive subdivision engine that we will look at in this exercise works a little differently as compared to the other three options available in that, instead of creating an internal pixel array that becomes more and more subdivided as the "Subdiv" parameter is increased, this engine instead creates a grid that is set to the same resolution or size as our render output and that then acts as an internal overlay. This is used by V-Ray to position or place samples in the seed. After making a first pass, the samples are compared and if the difference between any two samples is greater than the value set in the color threshold option, then the grid will be subdivided and more samples added. We do, if I just open up the "Render Setup" dialogue, have a couple of super-sampling options available. We have "Object outline" which will over-sample the outline of geometric objects in the scene. We have a "Normals threshold" option, which will super-sample objects whose normals have widely…
