it seems that I have a major problem with OpenGL graphics, beyond my limited IT skills, so I'm asking for some help and advice here.
Basically, I get the OpenGL rendering context - the gray background; I can change its colour, but nothing else works, like videoplanes, 3d objects (like plato), 3d text and so on. Not even the jitter tutorials.
I'm on a late 2011 macBook pro 15-inch,
CPU 2.4 GHz Intel Core i7,
GPU AMD Radeon HD 6770M,
OS X Lion 10.7.5
my openGL version should be fine (2.1): I tested it using OpenGL Extensions Viewer, and this is the report of the passed test (graphically everything was ok):
Renderer: AMD Radeon HD 6770M OpenGL Engine
Vendor: ATI Technologies Inc.
Memory: 1024 MB
Version: 2.1 ATI-7.32.12
Shading language version: 1.20
Could anyone point me to where the problem could be?
Thank you very much,
