Hi, All
Things go that I’m using multisample with GL_DEPTH24_STENCIL8_EXT and blitting between framebuffers. The source framebuffer’s code runs:
...
glBindRenderbufferEXT(GL_RENDERBUFFER_EXT,renderbuffer[DepthAndStencil]);
glRenderbufferStorageMultisampleEXT(GL_RENDERBUFFER_EXT,samples,GL_DEPTH24_STENCIL8_EXT,width,height);
glFramebufferRenderbufferEXT(GL_DRAW_FRAMEBUFFER_EXT,GL_DEPTH_ATTACHMENT_EXT,GL_RENDERBUFFER_EXT,renderbuffer[DepthAndStencil]);
glFramebufferRenderbufferEXT(GL_DRAW_FRAMEBUFFER_EXT,GL_STENCIL_ATTACHMENT_EXT,GL_RENDERBUFFER_EXT,renderbuffer[DepthAndStencil]);
...
Another framebuffer that is the target framebuffer goes the same way. But when I try to blit between them as following
glBindFramebufferEXT(GL_READ_FRAMEBUFFER_EXT,srcframebuffer);
glBindFramebufferEXT(GL_DRAW_FRAMEBUFFER_EXT,targetframebuffer);
glBlitFramebufferEXT(0,0,width,height,0,0,width,height,GL_DEPTH_BUFFER_BIT,GL_NEAREST); // *
the line * cause a memory access fault.
So how to modify the code to fulfill the task of this blit? Anyone can help me?
Dark Photon, can you help me?
