I have written a 3D Studio Max exporter which exports my 3D Models into my own PSO-Format. Ok, in this format, first I export all vertices and then the faces. A face has 3 indexes into the vertex-array. Now, I want to render in Direct3D Immediate Mode (DX 6) and want to use Triangle strips. How can I convert my data to triangle strips in a fast way ??? I have tried to simple use the vertex-array, but that's not working, I have to reorder them.
