| Does anyone have function or sourece to illustrate this? What I want to do is use a triangle in a mesh (unwelded I think) and calc the worldspace and UV then draw to that triangles texture (ala. lightmapping). This I think is also sometime called is point in triangle. There are several examples of this in other lightmapping BB programs and tutorials on the net but I seem to be getting it wrong. It would be great if someone had a function to allow me to pass a surface, trinagle, or alike and be able to render to that triangles/surface. Thanks for any help. :) L8r, |
