Can I use Pixel Buffer Object (PBO) to directly read the pixels values (i.e. using glReadPixels) from the FBO (i.e. while FBO is still attached)? If yes, What are the advantages and disadvantage...

I'm considering refactoring a large part of my rendering code and one question popped to mind: Is it possible to render to both the screen and to a texture using multiple color attachments in a Fra...

I wonder since a long time what would be the best way to handle OpenGL FrameBuffer Objects (FBO). Switching FBOs can be costly but defining new attachments too. How do you do it fast ? I hesitate...

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(...

I'm rendering into an OpenGL offscreen framebuffer object and like to save it as an image. Note that the FBO is larger than the display size. I can render into the offscreen buffer and use it as te...

According to ARB_geometry_shader4 it is possible to render a scene onto the 6 faces of a cube map with a geometry shader and the cube map attached to a framebuffer object. I want to create a shadow...
