在OpenGL中进行MSAA多采样时，需要进行如下设置FBO
glGenFramebuffers(1, &mfbo); glBindFramebuffer(GL_FRAMEBUFFER, mfbo); //create color render buffer glGenRenderbuffers(1, &colorBuffer); glBindRenderbuffer(GL_RENDERBUFFER, colorBuffer); glRenderbufferStorageMultisample(GL_RENDERBUFFER, 4 /* 4 samples */, GL_RGBA8, width, height); glBindRenderbuffer(GL_RENDERBUFFER, 0); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, colorBuffer); // multi sampled depth buffer glGenRenderbuffers(1, &depthBuffer); glBindRenderbuffer(GL_RENDERBUFFER, depthBuffer); glRenderbufferStorageMultisample(GL_RENDERBUFFER, 4 /* 4 samples */, GL_RGBA8, width, height); glBindRenderbuffer(GL_RENDERBUFFER, 0); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, depthBuffer); GLenum result = glCheckFramebufferStatus(GL_FRAMEBUFFER); if (result == GL_FRAMEBUFFER_COMPLETE) { isMultiFBODone = true; } else { isMultiFBODone = false; } glBindFramebuffer(GL_FRAMEBUFFER, 0); 如果程序中还需要使用蒙版缓冲（stencil buffer），则需要将此FBO设置为如下格式：
glGenFramebuffers(1, &mfbo); glBindFramebuffer(GL_FRAMEBUFFER, mfbo); //create color render buffer glGenRenderbuffers(1, &colorBuffer); glBindRenderbuffer(GL_RENDERBUFFER, colorBuffer); glRenderbufferStorageMultisample(GL_RENDERBUFFER, 4 /* 4 samples */, GL_RGBA8, width, height); glBindRenderbuffer(GL_RENDERBUFFER, 0); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, colorBuffer); // multi sampled depth buffer glGenRenderbuffers(1, &depthBuffer); glBindRenderbuffer(GL_RENDERBUFFER, depthBuffer); glRenderbufferStorageMultisample(GL_RENDERBUFFER, 4 /* 4 samples */, GL_DEPTH24_STENCIL8, width, height); glBindRenderbuffer(GL_RENDERBUFFER, 0); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_STENCIL_ATTACHMENT, GL_RENDERBUFFER, depthBuffer); GLenum result = glCheckFramebufferStatus(GL_FRAMEBUFFER); if (result == GL_FRAMEBUFFER_COMPLETE) { isMultiFBODone = true; } else { isMultiFBODone = false; } glBindFramebuffer(GL_FRAMEBUFFER, 0); 然后在根据需要写关于蒙版的代码即可 转载地址：http://ioeji.baihongyu.com/
