I have a Home coordinate system with 2 vectors and seperate coordinate system marked P1 and P2. Now I would like to draw a thick line between the two points, but the endline at each point should tilt according to the orientation of the local coordinate system. Is there a simple way to solve this by OpenGL commands or do I have to do ordinary matrix conversion/multiplication to find the corners. This last works, but costs some CPU.
first, did somebody answer your question? second, can you be more specific and give us more details as to what you're doing?
