Module materials 

Material system for surface rendering.

Materials define how surfaces are shaded. Blendable materials (clay, wax, candy, flat) use 4-channel matcap textures (R/G/B/K) for color-tinted lighting. Static materials (mud, ceramic, jade, normal) use a single matcap texture for all channels.

Structs

MatcapTextureSet

Pre-built GPU resources for a matcap material.

Material

MaterialRegistry

Registry for managing materials.

MaterialUniforms

GPU-compatible material uniforms.

create_matcap_sampler

Create a linear filtering sampler for matcap textures.

decode_matcap_image_from_file

Decode an image file from disk into float RGBA pixel data.

init_matcap_textures
