Hello,
I have a strange problem where I have picking code that works under a Win32/MFC application, but doesn’t work in an ActiveX control environment. General rendering works fine, but when I try to pick something, the following routine:
glGetIntegerv( GL_VIEWPORT, viewport );
does NOT set the viewport array!!! Even if I hardcode the viewport array, picking still doesn’t work, so I suspect something is afoot in the OpenGL subsystem. But what?
Has anyone ever got picking to work under an ActiveX control window? Any ideas?
Thanks very much in advance,
John
