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

As far as I know, Intel graphics dont support OpenGL, which is required for Gem to function.

Can't be, hopefully. Intel is one of few, I think even the only one, who provides open sourced drivers for Linux which also supports hardware accelerated 3D through OpenGL and there is a similar situation on OSX. The Intel chip is in the Mac Minis and Mac Books and at least games are reported to run on that computers. Not all OpenGL operations (like vertex shaders) are done in the graphic hardware of the 950 chip indeed, so the performance is less then Nvidia or Ati, but Intel improved that with the next generation of graphic chips, X3000 and onwards are more desirable.

Hi Malte,
that's right, Intel GMA 950 provides some API support (including openGL 1.4).
GEM runs without any problems.
It's still strange that I can't enable GL_Multisampling or any kind of smoothing
in GEM on the Macbook ---> and anti-aliasing with [text2d] works.
Anyone knows if there's the same logic behind text- and polygon-smoothing?
[FSAA $1( just seems to work with nVidia-gfx-cards...

I'd be happy about any hints!
Cheerio

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.

[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..
