Today I found that XBox360 has tessellation feature.
I thought tessellation or geometry shader is supported from DirectX10 so that I was very excited by finding this. Tessellation is simply saying when I pass one triangle, I can use more than one triangles as the result. It is supposed to be fast and efficient due to hardware support.Actually I haven't been paying attention on geometry shader or tessellation, because I thought we cannot use it yet. I always skipped those parts when I read books. Now I need to track back and check what kind of techniques I can use with it.
It seems like PS3 doesn't have any similar functionality. Sony might think of SPU as the counter part.
Unfortunately the XBox360 SDK document doesn't explain about the tessellation at detail; for example performance or caveats. In addition, I haven't heard any XBox360 games have been using the tessellation feature before. It makes me wonder how useful it will be.
