I have some question about collision detect.
I was thinking how to make one, and come to the selection render mode. I was thinking if I could draw only one point then I could check if both object are drawn at this point.
My problem is that I don’t know how to do it.
I can check which object is at a final screen coordinate, but I want to check it in real world coordinates (x,y,z).
I have another question. How can I get the final vertex coordinates?
I mean I define a few vertices and then I move and rotate and scale them. How can I get the transformed vertex coordinates.
Thanks in advance
