Module pbr 

Physically Based Rendering (PBR) material system.

Provides PbrMaterial, material presets, a material cache, and GLSL uniform block generation. Sub-modules contain the full BRDF library, atmospheric rendering math, and environment probe / global-illumination helpers.

Modules

atmosphere

Atmospheric and environmental rendering mathematics.

brdf

Complete BRDF (Bidirectional Reflectance Distribution Function) library.

probe

Environment probes and global illumination helpers.

Structs

GlslMaterialBlock

Generates GLSL source code for a uniform block that matches the layout of a PbrMaterial. Use this to keep CPU-side structs and shaders in sync.

MaterialCache

Content-addressable, LRU-evicting cache for PbrMaterial values.

MaterialKey

A hash key derived from the content of a PbrMaterial. Two materials that are structurally identical produce the same key.

MaterialPreset

Factory methods that return physically plausible PbrMaterial presets for common real-world materials. All values are based on measured data where available.

PbrMaterial

Complete physically based rendering material definition.

TextureHandle

Opaque handle to a GPU texture resource. The renderer back-end maps this integer to an actual texture object.

Enums

AlphaMode

Controls how the alpha component of albedo is interpreted.
