I am trying to implement selecting a node in a terrain (represented by triangle
strips). However I cannot use glPushName() between glBegin/glEnd, so I can only
save the whole strip in a name buffer.
Any other ideas how could I select a specific node/triangle with the mouse?
I know that by creating GL_TRIANGLE objects instead of the triangle strip would
solve my problem, but wouldn’t that be much much slower?
Thanks in advance
OpenGL’s selection mode has been deprecated, you should use a CPU-based ray picking algorithm instead (if you really care about picking performance).
