In my opinion the every glClear() delete left and right buffer together. What must i do to cancel only one buffer?
What you posted is the perfect clear and render sequence for stereo rendering on a stereo pixelformat.
Keep it this way if you’re working in stereo!
GL_BACK means both left and right back color buffers in double buffered stereo.
GL_FRONT_AND_BACK means all four color buffers then.
BUT!!! There is only one depth buffer in spec conformant stereo implementations.
If you don’t have a stereo pixelformat, GL_BACK_RIGHT should throw an error and GL_BACK_LEFT == GL_BACK in monoscopic formats will remain the target.
sure, i have set up PFD_STEREO in pixel format…
