audio-reactive-shaders data

Precomputed data and images for the shaders in audio-reactive-shaders. Fetch it with that repo's download_data.py (resumable, SHA-256 checked, pick groups: kerr, nebulabrot, diamonds, ringbox, embers, dwarf, gems, tunnel, phone); the paths here match the repo's 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/lens_inv*.npy	The same bake inverted into a position-indexed lens grid (lens_inv_bake.py)
textures/slurp/gasbake_flip.npy	A torn star's gas stream and disk, pre-lensed: 85 frames rendered offline by the original Kerr-Newman renderer
textures/kerr_v7/kn_disk_table*.npy	Accretion disk emission tables (kn_disk.py)
textures/starfield/gaia_cube_g117_max/*	Gaia DR3 stars (G < 11.7) as a BC6H cube map (tools/gaia_fetch.py, gaia_cube_bake.py)
textures/starfield/nebula_photo4.npy	Milky Way dust and two nebulae, hand-edited photos placed on the sky
textures/starfield/sky64k/*	Older NASA SVS Deep Star Maps 2020 cube map (no longer used)
textures/pulsar_orrery/*.npy	Star, planet and ring surface maps (pulsar_orrery_prep.py)
textures/nebulabrot/*.npy	Buddhabrot density bakes (nebula_bake_modal.py)
textures/illusion_diamond/backdrops/*	Stained-glass windows with their pane data (stained_glass_prep.py), the diamond's portal picture, the checker tunnel
textures/stained_glass_space/*.png	The glass box's stained-glass walls
textures/moon_sphere/, textures/ringbox/	Moon surface, sun photosphere and 304 Å maps
textures/brown_dwarf/, textures/fbm_drop_v3/	Lightning bolt atlases, grown on the GPU by dielectric breakdown
textures/fbm_drop_v6/*	The gem sphere's backdrop image with its depth and normals
phone/backdrops/*.png	Glass-box wall images for the phone wallpapers

paths32.npy has one bake defect repaired: 57 rows where sample #9 came out zero.
