Here is a voxelized stanford dragon mesh.
Longest axis is 512 here.
Uncompressed, the volume is ~200mb(f32).
Spent some time working on a compression method.
It supports random access without prior decompression like S3/dxt.
It turns out SDFs are very compressible if you think about which information really matters.
Lossy, but not really observable.
New size: 3.39 mb in memory
On disk with zstd(22): ~800kb
Here are some papers to investigate in the future, although these do not store SDF's, they are more like SVO and only store filled/not filled.
And this one for storing color information.
