Join Aaron F. Ross for an in-depth discussion in this video Controlling displacement tessellation, part of Creating Shader Networks in Maya and mental ray.
We've added a Displacement Map to deviate the shape of the ground plane outside our window.…What we want to do here is just optimize performance. We want achieve the result of …we have a highly detailed surface, but we only want that to be just…detailed enough and no more.…We control the quality of the Displacement through the NURBS Tessellation Attributes.…Basically there are two things involved in here. First of all, there's the amount of …Tessellation for the NURBS surface.…
Tessellation of course is tiling or splitting the object up into polygons.…I have a very high tessellation here for the object itself.…Additionally, we've got tessellation for the displacement. This is another…level of Tessellation that happens after the Displacement Map has been applied.…You'll see Initial Sample Rate and Extra Sample Rate.…Initial Sample Rate is how many times a polygon is subdivided as it's being displaced.…
Then the Extra Sample Rate is an additional level of subdivision…that's applied in order to enhance sharp edges and features.…
