  • Calculating normals for large mesh with no vertex to triangle info

      • I have a mesh of 100.000 triangles where I need to calculate the normals for the vertices. The datastructure, I am using, does not point from vertices to triangles, but only the other way arround. I therefore defined my vertex normals as the sum of the triangles using them, weighted by the triangles size. I simply set all vertex normals to zero and then run through my triangles (when running

      • First off, I'd like to commend the developers of XACT for making such a user friendly program for those of us not super technologically savvy. Great program. My question is this. I've created an RPC for the attack/release time in background music we're using for a game. However, I've noticed that the upward limit on both attack and release is 15 seconds and I haven't been able to find a way to

      • Currently volume textures aren't supported in the Content Pipeline. So if I have a mesh that references a volume texture it will fail compiling. So, is it just a matter of writing a custom importer for volume dds files or is it all the way through the pipeline Will ContentManager.Load<Texture3d>(...) work if I just write the importer Say it is so...it is Christmas after all :-)
