Hi,

I tried to use Anatomist with a graphic card is a chipset : Mobile Intel (R) 82915 6/GV, 910 GL Express Chipset Family. (Version 3.0.2, windows) and I am not able to display an image some texture are not avaible. I d/l the last version of driver for my card but nothing happens.

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

Nico

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 :

Hi,

Yes a tried to reduce the graphic acceleration but nothing changed

Nico

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

Isa

I recieved DTI color map from a collaborator using Anatomist and I wanted to open them

Nico

Could you try with other data ?
You can download demonstration data on the web site http://brainvisa.info/downloadpage.html ortherwise I can send you data.

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,

Nico
