Hi, I would like to perform tessellation on a 2D closed polygon. In fact just like you can with OpenGL using its GLU Tessellation Functions. Now I am using managed DirectX 9.0, and for the life of me can not find an equivalent in DirectX. Am I searching in vein guys, any comments appreciated? Julian

I would look into the Direct3DX library (and the Mesh class in particular, which AFAIK provides tessellation for certain things).

Hi, I had looked at Meshes, but I assumed meshes are made from triangles in the first place. This is not what I have, my polygon is made up of a series of line segments, one after the other. Is this considered a mesh?

Thanks for your help in this matter

There are no d3dx tesselation functions, I simply use the gluTesselation stuff in combination with dx :)

Cant you do that as well ?

Thanks for the reply, at least I know it does not exist.
Yes I think I will try and use glu
