Could any SGI box render to texture without CopyTexture?
If I recall correctly from my O2 days, you had to CopyTexture from a DMBuffer in order to do the "video as texture" effects for which the O2 was famous. What I don't remember is if the DMBuffer could be configured in some way so that no CopyTexture was needed, and it was actually used directly as a texture. I don't know either if the later VPro had FBOs with render to texture.
What I did back in the days for this was pbuffer->CopyTexture->render in window, but I'm wondering if a more direct path was ever available at some point.
