[PD] fsaa with intel gma950 / OS X?

[Jan Thoben]

[polygon_smooth] doesn't work either.
mmh.., does a software rendering fallback make sense for 3d?
is this supported by gem on linux? maybe it's worth a try with the same hardware
but a different platform... it's really disappointing that you can't replace the chipset..

Either the Intel GPU doesn't support FSAA at all or turning it on reverts to software rendering.  The former is possible since the GPU has so little power to begin with.  GEM doesn't support software rendering on OSX and there is a chance that something fails silently and then goes back to 'hardware' rendering.  The Intel chip only does a tiny amount of actual hardware rendering for the pixel pipeline and almost nothing for the vertex although testing reports full hardware OpenGL functions.


The anti-aliasing done by the text objects is a very old type of AA which is disabled on Nvidia and ATI parts in favor of FSAA.  If that works you can try the [polygon_smooth] object before any geometry drawn.

Hi List,

I have been trying to get full-scene anti-aliasing and [polygon_smooth] to work on a Macbook (which has Intel's integrated GMA950 chip) with Gem ... No success. Gemwin seems to get the message but won't show any effect.   


[FSAA $1(

[gemwin] 

works perfectly well on a Power Book G4 with nVIDIA GeForceFX Go5200...
Is there any other way to enable the Intel chip to perform openGL FSAA? [alias $1( for [text2d] works with the chip!


Thanks,
Jan
