GL_Multisample_ARB and FBO:s

Recommended Posts

Hi, a quick question. I'm aware that GL_Multisample_ARB doesn't have an effect when rendering to a texture (if you don't have the GL_EXT_framebuffer_multisample extension), and according to the spec. the GL_POINT_SMOOTH, GL_LINE_SMOOTH and GL_POLYGON_SMOOTH is overridden when having enabled the multisampling. But what about when rendering to a texture and having everything enabled? Does the multisampling still override the ordinary smooth-ops even though it is not in effect? I guess it's a quick thing to create a test app and see for myself, but I'm too lazy for that ;)

I think you should be fine as long as the surface itself has no multisampling. So say you are in your FBO, and you have MS renderbuffers, you'll see the SMOOTHs disabled. But since you are doing an RTT, and that doesn't support MS currently, you should be fine.
