In my engine I need a selection system that works for simple picking and dragging.
However dragging won’t work with GL selection buffer which is what I’d use. I don’t know of any other kind of geometric selection, so I’m thinkin that I have:
about 300 points, 300 points possible on the screen
will use gluProject to find the screen 2d positions of these points so they can be compared to the 2d mouse pointer to see if the mouse has selected them
But I’ve read that gluProject may not be efficient enough to do this. Beware this is a game where speed is important.
Please give me lots of info I’ve spent many hours on the problem.
it seems to me this would be the best solution.
