Multi-sampling
Author
Can multi-sampling be done in a render to texture setup? I am using a lot of FBOs as render targets, and I have done what I can to enable multisampling, but with no results.
Are there any ways around this?
Thanks!
currently; no.
however, a new extension has been added to enable you todo this, as to what hardware will support it however I dont know (I'm hoping at least R300 from ATI and NV40 from NV).
If you want multisampling now then you'll either have to copy from a multisampled framebuffer, use a pbuffer (I think you can enable it for them) or maybe fake it yourself with a fragment program when rendering your texture to the screen.

You mean enable multisampling on the back buffer and copy from that to my FBOs?
copy from that to a texture (which shouldnt be an FBO target iirc as that can slow things down a great deal)
