[PyOpenGL-Users] Picking in OpenGL. Working example neede.

[Lothar B. <lb...@un...>]

Hi everybody,

I try to get picking to work in my little pythonic 3D viewer. Can
somebody point me to a working example using generic OpenGL calls. I
looked at some but they are based on togl and the real picking is buried
somewhere. I would like to use the OpenGL name stack.

Any help appreciated.

OpenGLContext has most of the code you're likely to be interested in, 
look at SelectRenderPass in the renderpass.py module.  That's part of a 
very generic framework, so isn't a stand-alone demo, but as a result, 
what you see there is basically *just* what you need to do to accomplish 
a selection render pass.  Afraid that's the only demo I have to hand 
that uses GL_SELECT mode.

Good luck,
Mike
