Expand description

GPU-friendly representation of a light source for compute shader processing.

This structure is designed for efficient GPU transfer and compute shader access. It uses a unified layout that can represent all light types.

§Memory Layout

Total size: 64 bytes (16 × 4-byte floats), well-aligned for GPU access.

Fields§

§position: [f32; 3]

Light position in world space (ignored for directional lights).

§range: f32

Maximum range of the light (point/spot lights only).

§color: [f32; 3]

Light color (RGB, linear space).

§intensity: f32

Light intensity multiplier.

§direction: [f32; 3]

Light direction (normalized, for directional/spot lights).

§light_type: u32

Light type: 0 = directional, 1 = point, 2 = spot.

§inner_cone_cos: f32

Cosine of inner cone angle (spot lights only).

§outer_cone_cos: f32

Cosine of outer cone angle (spot lights only).

§_padding: [f32; 2]

Padding to ensure 64-byte alignment.

Implementations§

impl GpuLight

pub const TYPE_DIRECTIONAL: u32 = 0u32

Light type constant for directional lights.

pub const TYPE_POINT: u32 = 1u32

Light type constant for point lights.

pub const TYPE_SPOT: u32 = 2u32

Light type constant for spot lights.

Trait Implementations§
