Structs

DirectionalLight

A directional light (e.g., sun).

LightInjectionConfig

Configuration for light injection.

PointLight

A point light.

ShadowMap

A shadow map with depth data.

SpotLight

A spot light.

Enums

LightSource

Constants

INJECT_COMP_SRC

Embedded compute shader for GPU light injection.

Functions

inject_direct_light

Inject direct lighting into the voxel grid.

inject_direct_light_with_config

Inject direct lighting with configuration.

inject_emissive

Inject emissive lighting: self-illuminating voxels contribute their emission as radiance.

inject_emissive_from_sh

Inject emissive lighting from a separate emission channel stored in sh_coeffs[0].

pcf_sample

Percentage-closer filtering for soft shadows.

shadow_test

Test visibility of a world position against a shadow map. Returns 0.0 for fully shadowed, 1.0 for fully lit.
