SDK DetailTessellation11 help
I am learning tessellation and im currently using the shader from the sdk example DetailTessellation11.
I am now having a weird problem with flickering and one of the objects behaving strangely, going invisible for a while then coming back.
I noticed that you need the vertices in tangent space? How do I do that?
I have actual tangent coords in my vertex but I dont know how to make the actual vertex position be in tangent space.
The output from the tesselator stage contain barycentric coordinates, which I think is what you mean by tangent space vertex positions. In my engine (see link below) is a 'BasicTesselation' sample that shows how that works and how to recreate the WS position from barycentric coords.
