Join Brian Bradley for an in-depth discussion in this video Controlling the Adaptive Subdivision sampler, part of SketchUp Rendering Using V-Ray 2.
- The adaptive subdivision engine…that we will take a look at in this exercise…works a little differently as compared…to the other image sampling options that we've looked at…in that instead of creating an internal pixel array…that becomes more and more subdivided,…as a subdiv parameter is increased,…this engine instead creates a grid…set to the same resolution or size…as our render output that is then used…as an internal overlap.…This is used by V-Ray to position…our play samples in the scene.…After making a first pass using the minimum…number of samples available,…the sample results are compared…and if the contrast difference…between any two samples is greater than…the value set in the color threshold option,…then the internal grid will be further subdivided…and more samples added.…
Now you may already have noticed…that instead of min and max subdiv values here,…we have a min and max rate setting.…These controls work quite a bit differently…than the straightforward subdivision method…used by the other engines and so we do…
