GL_ texture not avaible

Post by nicolas.kunz »

Hi,

condole log:
GL_SGIX_shadow extension not avaible
GL_SGIX_depth_texture extension not avaible
GL_ARB_depth_texture extension not avaible
GL_ARB_texture_cube_map extenstion not avaible
GL_EXT_texture_cube_map extension not avaible


Thanks

Hi,

Your chipset seems compatible with OpenGL. We already worked on this kind of worksation with graphic chipset and it was ok. Did you try to change the graphical properties ?
We often see a problem about the graphic acceleration and texture display. You can read a solution on :

I hope and suppose Denis will have a better idea.
Which kind of data did you try to display ? T1, T2, 2D image .... ?

Hi,
What does anatomist display ? Just nothing (all white window) ? Part of the objects ? Missing textures ?
I am a bit surprised that there is no other message in the console: generally when there is a problem with OpenGL, messages like "bad GL list" or "Texture too large" are printed in the console output. So I wonder if you have at least put the objects in the view ?
Denis

PS: warnings about missing extensions are not a problem: normal OpenGL rendering routines do no need them.

Hi,

You were right, this "error" msg stop me. I tried again a bit further and now it is working after slowin down the graphic acceleration.

Thanks for your quick and precise answer

Cheers,
