CauldronGPU.Sectors.Surfaces (CauldronGPU v0.3.3)

Copy Markdown View Source

Convex polygons gathered into one CauldronGPU.Mesh, one part per material key.

A surface is {key, corners}: key names its material (any term), corners are at least three {position, normal, uv, light} in counter-clockwise order seen from the side they face, positions and normals in map coordinates (+Z up) and light a sector light level 0..255, read through CauldronGPU.Sectors.Light.uv/1.

{mesh, keys} = CauldronGPU.Sectors.Surfaces.mesh(surfaces)

keys lists the material key of each part, in part order.
