audio-reactive-shaders data
Precomputed data for the Kerr-Black-Hole-Visualizer shader in
audio-reactive-shaders.
Fetch it with that repo's download_data.py (resumable, SHA-256 checked);
the paths here match the repo's textures/ layout.
Proof of concept, not maintained.
| file | what it is |
|---|---|
textures/kerr_v7/kn/paths32.npy |
Null geodesics around a Kerr-Newman black hole (a* = 0.997, Q* = 0.07), 32 path samples per pixel for a 2410x2410 view (kn_bake_modal.py) |
textures/kerr_v7/kn/sky.npy |
Where each pixel's light ends up on the sky, up to 4 images per pixel |
textures/kerr_v7/kn_disk_table.npy |
Accretion disk emission table (kn_disk.py) |
textures/starfield/sky64k/* |
NASA SVS Deep Star Maps 2020 at 64k, as a BC6H cube map with mips (skycube_unpack.py, skycube_bake.py) |
textures/pulsar_orrery/*.npy |
Star, planet and ring surface maps (pulsar_orrery_prep.py) |
paths32.npy has one bake defect repaired: 57 rows where sample #9 came out zero.
