To do so, we …

Blue noise uses Gaussian energy functions during its creation so it is optimized to be removed by Gaussian blurs. If you blur blue noise with a Gaussian function and are seeing noisy blobs remain, that means you must use a larger sigma in the blur, due to the lower frequencies of the blue noise passing through … Meer weergeven Neighboring pixels in blue noise textures have very different values from each other, including wrap around neighbors, as if the texture were tiled. The assumption is that when you have a function that renders a pixel , small … Meer weergeven The energy function of vector valued spatiotemporal blue noise can be modified to return nonzero only if the following conditions are true: 1. The pixels are from the same … Meer weergeven There may be times you want more than one spatiotemporal blue noise value per pixel, like when rendering multiple samples per pixel. One way to do this is to read the … Meer weergeven If you have a scalar spatiotemporal blue noise texture, you can put it through an inverted Morton or Hilbert curve to make it into a vector … Meer weergeven Web22 dec. 2024 · DiffusionTransparency Dither applies a random pattern that is usually less noticeable than Pattern dither.
