I'm trying to enable mutlisampling and alpha-to-coverage for an FBO. Using the default framebuffer, all I have to do is call glEnable(GL_MULTISAMPLE) and glEnable(GL_SAMPLE_ALPHA_TO_COVERAGE). Howe...

I know webgl can antialias or multisample stuff you render to the screen to avoid hard edges, but when I used a framebuffer it didnt do it anymore and there were a bunch of jagged edges on the scre...

I'm trying to get multisampling working with MTKView. I have an MTKView with a delegate. I set the view's sampleCount property to 4. I create a pipeline state descriptor with the rasterSampleCount ...

I'm developing a little gamedev library. One of the elements of this library is a Canvas (offscreen drawing area), which is implemented through an OpenGL framebuffer. So far, everything's been good...

What does setting this variable do? For instance, if I set it to 4, what does that mean? I read a description on glfw.org (see here: GLFW Window Guide) under the "Framebuffer related hints" secti...

I'm learning directx 11 and trying to set up multisampling. For some reason every tutorial on the internet disables multisampling and never goes over how to enable it. First: I've searched around...

How do I enable multisampling when I create the window? How should I initialize OpenGL to match?

I'm trying to do multisampling with SDL/opengl but SDL won't accept setting SDL_MULTISAMPLEBUFFERS and SDL_MULTISAMPLESAMPLES. Instead these are left at 0 and SDL_SetVideoMode() will fail afterward...

Although I have been discouraged from reading the OpenGL redbook, I am still doing it, because it is the only book designed for beginners, and tutorials and/or documentation don't quite substitute ...

I'm trying to render a multisampled scene to texture, here is the code I'm using. I'm getting a black screen. I check the fbo completeness at the end of init, and they report that both fbo's are co...

I am very interested in understanding how multisampling works. I have found a large literature on how to enable or use it, but very little information concerning what it really does in order to ach...

I'm experimenting w/ improving the "resolution" of an OpenGL ES based app. Apple mentions here (developer.apple.com) that OpenGL ES in iOS 4 supports multisampling... and this can improve the graph...

I usually create a pixel format using wglChoosePixelFormatARB() with these arguments (among others): WGL_DOUBLE_BUFFER_ARB = GL_TRUE WGL_SAMPLE_BUFFERS_ARB = GL_TRUE WGL_SAMPLES_ARB = 4 i.e. dou...

I'm using an FBO to render my scene to a depth texture (GL_DEPTH_COMPONENT). When I enable multisampling in my application, those samples are resolved to a single texel, but how are they combined? ...

I have an FBO object with a color and depth attachment which I render to and then read from using glReadPixels() and I'm trying to add to it multisampling support. Instead of glRenderbufferStorage(...
