Major OpenGL problem

February 25, 2014 | 4:16 pm

Hi all,

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

Device: MacBookPro8,2

Shading language version: 1.20


Could anyone point me to where the problem could be?

Thank you very much,

Marco

did you set the context name argument?

without seeing a patch, there’s really no way to know.

yes, I did.

for example, jitter tutorial 30 (the first, I think, involving OpenGL) doesn’t work properly: it doesn’t show the 3D text nor the axes, nothing actually. Apart from the gray background.

here’s a patch of mine which doesn’t work, but, since I could never get OGL to work, there’s no way for me to tell whether its code is right or wrong:

are there any error messages reported in the max window?

which version of max are you running?

32 or 64 bit?

Hi, no I don’t get any message in the max window, apart from "jitter initialized".

I’m running max 6.0.8 32 bit.

Is there anything i could try before completely reinstalling it?

i would update to the latest version of max
