I have a my scene which I am flying through. I am constantly doing range
calculations on the z-buffer with multisampling off and shipping them off
to other processors. I get some feedback from these processors and I would
like to mark an x,y location in my scene, every frame, with a crosshair or
colored dot that will not mess up my z-buffer scene range calculations.
So, I have two questions:
1. Is there a way to have the crosshair not interfer (i.e., if it is in
front to be seen, it will definitley be in the zbuffer if I use the common
method) ??
2. What would anyone suggest as a "nice" way and "the fastest way" to draw
the crosshair or colored dot in my draw callback routine even if it
interfers?? Is OpenGL in the draw callback routine going to be the
fastest?
Thanks, I've only been at this stuff for a month and a half and I am
finding everyone very helpful.
