I'm creating an interactive 3D-Molecule-kit for chemistry teaching and I experienced some problems with ati-cards.
When I try to draw smooth lines this way:
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
gluLookAt(mycam.pos, mycam.pos, mycam.pos, mycam.focus, mycam.focus, mycam.focus, 0,1,0); //3D-projection
I get usual (non-antialiased) lines with ati cards. When I execute my code on nvidia cards then it works perfectly.
The same behavior appears, when I try to use the accumulation buffer to do full-scene antialiasing or motion blur.
With nvidia cards -> it works
With ati cards -> no effect
Is there any way to enable antialiasing (FSAA) in OpenGL by using GLUT and ATI-Cards?
Or is there a command to force ati-cards to FSAA? May be like the option of Antialiasing in ATI Tray Tools?
Thanks for any help
