Currently I am programming a computer game that will use a BSP tree. I can currently make the bsp tree, and handle triangle splits. The only only problem im having is finding the texture coodinates for the new triangles that I create when a plane splits a triangle. I have the original triangles vertices and texture coordinates, and I have the new triangles vertices, how do I calculate the new texture coordinates? Go on an Intense Rampage

Finding splitted vertices is some kind of interpolation, in a little modified form (depending on how you do it of course). Just "interpolate" the UV-coordinates too, much like the vertices.
