Why does glRenderMode(GL_RENDER) fails sometimes?


I really hope someone can help me.

I’m doing the select mechanism and sometimes picking/seleting doesn’t work.
That means, I receive 0 as result from glRenderMode(GL_RENDER).

I think it is worse after I rotate and zoom the object. But I don’t know how to solve this!?

Any ideas?

Thanks ,


I got it!

Had a different aspect/ratio in my gluPerspecitve which I used for selecting.

sorry for posting!
