fragment shader & multisampling

by Antonio Bleile <antonio.bleile@[EMAIL PROTECTED] > Jul 15, 2008 at 08:21 AM

Hi,

let=B4s say I have a 16xmultisampled Pbuffer of siye 1024x1024
and I want to render a textured quad on the view****t using a
fragment shader (I want to do some image processing
using shaders (e.g. blur, color transform etc)). Ideally the
fragment shader should get called 1024x1024 times. But
as multisampling is enabled, it might get invoked more
than that, right? The question is, how many times precisely?
I tried to call glDisable(GL_MULTISAMPLE_ARB); but it
was still slower than rendering into a non-multisampled
Pbuffer....

Any comments?

Thanks and kind regards,

  Toni
