Notes. Results of the SC transform provided by s2scat. These results were recovered on a single NVIDIA A100 40GB GPU, although it is possible to run across multiple GPUs. In our analysis we generate spherical images through 400 iterations to be conservative. In practice, however, we find that ∼100 iterations is typically sufficient, in which case an image at L = 256 can be generated in ~4s. Furthermore, batched generation can dramatically decrease per sample compute time. For example, 20 images at L = 256 can be generated in ~12s, corresponding to ∼0.5s per sample.
