Hi, In my application, I need to render 2 buffers : - color buffer - "object-code" buffer
I obtain the color-buffer by normal rendering to an FBO. For some algorithms purpose (object tracking, objects statisitics, etc...) I need also an "object-code" buffer with, for each pixel, an int value corresponding to the object. I can do this with a shader in another FBO, but I need this buffer to be not antialiased at all. For example, if the background code is "0", and there are 2 objects in the scene (codes "10" and "20") the final "object-code" buffer must be filled with "0", "10" and "20" but no other value. How can I configure my rendering to do so ? Maybe using the stencil buffer as a object-code buffer (I don't know if antialiasing such as MSAA affect stencil buffer) ? Thank you!
