Hey Marius, I think FSAA only happens on the final render... Perhaps there is some shader cmd to AA a pix_? maybe a hypothetical pix_antialias could be useful? (but slow on the CPU) seems problem for a shader to me. .b. marius schebella wrote: hi, is there a way to get an antialiased texture

Alternatively if your render supports multisampling you could do a GEM_glEnable(GL_MULTISAMPLE_ARB) or GL_MULTISAMPLE, assuming it is enabled for the contexts pixel format, but that would be a good solution.. youd have to use glDefine(GL_MULTISAMPLE_ARB) however :) On Apr 21, 2008, at

Not for an FBO. Nvidia has an extension to do this, but I only recently got the hardware to test it (and that hardware is in use as you know). On Mon, Apr 21, 2008 at 1:02 PM, vade [EMAIL PROTECTED] wrote: Alternatively if your render supports multisampling you could do a

Ah, am sorry, I did not see antialiased texture. I redact my statement. However if you are rendering geometry to a gem framebuffer (render to texture, you should be able to antialias BEFORE rendering to the FBO, which if things work correctly, should result in antialiased contents within

I am still not sure, how I should do it. (or if it is possible at all). I am rendering 100s of geos into a gemframebuffer once. and then put it on a plane to use as a background image. I would not know where I could apply any antialiasing, because I am not dealing with textures before they are

hello, it's possible to render your geos in a 2048*1532 frambuffer, then use this as a texture. render this texture throw a shader that average 4 pixels in 1 in order to anti-alias this texture to a 1024x768 window. cyrille marius schebella a écrit : I am still not sure, how I should do it.
