Module cube 

Cubemap face primitives.

CubeFace enumerates the six faces of an axis-aligned cube in the order wgpu expects when indexing a texture_cube / texture_cube_array:

0: +X    1: -X    2: +Y    3: -Y    4: +Z    5: -Z

It is the foundation for omnidirectional shadow mapping (point-light shadows), reflection probes, IBL, and any other code path that needs to enumerate or sample a cube’s faces. The “up” vector returned by CubeFace::up matches the cubemap convention used by wgpu / Vulkan / D3D11 — the +Y / −Y faces use ±Z as their up vector to avoid the singularity where look_at_rh(eye, eye + Y, Y) is degenerate.
