[Bf-committers] FSAA and Blender

[Kester Maddock]

Hi Ton,

The ARB_multisample extension is what you want:
(http://oss.sgi.com/projects/ogl-sample/registry/ARB/multisample.txt)

Basically, once a window has been created with a multisample buffer, use:
glEnable(GL_MULTISAMPLE_ARB);
glDisable(GL_MULTISAMPLE_ARB);

I'm not sure if the control panel setting overrides this though.
