[gl4java-usergroup] accumulation buffer

[Thorsten R. <tho...@iv...>]

Hi *,

is it right using the accumulation buffer is really _slow_ ?

Regardless of the value of accum bits set, I've 0,5fps in the accanti demo...
(1GHz, 512Ram, RedHat7.1, GeForce2MX, nvidia-1.0-1251)

I'm trying to use the accum buffer because I need to set an alpha value to a 
fixed display list with glColor's in it. With the accum buffer I should be 
able to add an already rendered display list with any alpha by glAccum 
(GL_ADD, alpha), right ?

Is there a way to set the color (r,g,b) without setting the alpha too ?

regards,
