Stupid question - do you generate different patterns of poisson noise on every frame?
- Kubuxu 4y agoAs they grain of each film frame is independent, you should but there are many techniques to avoid that, generate larger noise texture than your target size and use it with random offset, additionally you randomly mirror it in either direction.
- mgraczyk 4y agoI do, it's fast enough and done with integer arithmetic. I have seen others use pre-generated noise patterns.
