Hi I am using TriangleFunctor to do some very simple collision detection. Essentially I have a virtual pen (the collision detection is treated as a sphere on the tip of the pen) that I am testing for collisions against other geometry in the scene. The geometry I am testing against is loaded from OBJ files using osgDB::readNodeFile(). Once I have found a collision with the pen, I would like to update a texture image (drawing on the virtual object). However, I am unsure how to access the texture coordinates for the triangle I have just tested with.
How am I able to do this with TriangleFunctor? Or, is there another method I should be using for my collision detection that will give me access to the texture coordinates of the triangle. Thanks Michael
