I have a rectangle that i need to clip (i mean clip pixels inside my area, not outside). glScissor works almost like i want, but as i said, i need to clip pixels INSIDE my area, but scissor works vice versa. Does glScissor can make thing that i need, or GL has other methods?

Here example what i need to do (I drew picture for example):

  • The efficient way would be via GL_NV_scissor_exclusive, but this one is nvidia-specific and not very widely supported in general, but GL_EXT_window_rectangles also offers such a functionality, and is more widely available. Commented Jun 13, 2022 at 16:47
