Reminds me of:
- A Quadrilateral Rendering Primitive (2004) - Paper PDF (Hormann, Torini)
- A Quadrilateral Rendering Primitive (2010) - Youtube (Hormann)
- Quad Rendering Code (2017) - Supermodel Forum Thread (Ian)
See the last link above for GLSL code showing how to do this in OpenGL.
I think there was a thread here on this on this a few years back. Ah! Here it is:
- Nvidia 441.41 driver bug? (2019) - Khronos Forum Thread (dukey)
