Module meltsphere 

Sphere-region voxel extraction (meltsphere) and its support tables.

Port of voxlap’s meltsphere (voxlap5.c:10222-10344). Walks an AABB-bounded sphere of voxels in the world and packages the visible (border) voxels into a fresh kv6 sprite.

Supporting helpers:

• lightvox — alpha-byte face shader (voxlap5.c:623-632).
• PowerTables + PowerTables::build_tempfloatbuf — the factr / logint / tempfloatbuf machinery (voxlap5.c:118-120 statics, :12224-12236 init, :10240-10252 per-call build).

Structs

MeltsphereOutput

Output of meltsphere — a freshly-built kv6 sprite plus the computed sprite centroid and total solid-voxel count.

PowerTables

Tables that voxlap precomputes once in initvoxlap and reuses across every meltsphere / setsphere call.

Functions

meltsphere

Region-grow a sphere of voxels out of the world into a kv6 sprite.
