Source: https://eheitzresearch.wordpress.com/762-2/ We provide our samplers optimized for N = 1, 2, 4, 8, 16, 32, 64, 128 and 256. Each sampler generates up to 256 spp in a 128x128 wrappable tile. The blue-noise distribution of the error is - optimal when spp=N, - good when spp<N and spp is a power of two, - cancelled when spp>N. Each sample has up to 256 dimensions. We optimized only the first eight dimensions by pairs, i.e. we computed four optimizations for D=2. Each .cpp file provides: - the Owen-scrambled Sobol sequence (256 samples x 256 dimensions). - the scrambling tile: 128x128x8. - the ranking tile: 128x128x4. It is actually 128x128x8 but the data are currently duplicated. This can be optimized.
