Struct GpuLight 

pub struct GpuLight {
    pub position: [f32; 3],
    pub radius: f32,
    pub color: [f32; 3],
    pub intensity: f32,
    pub casts_shadow: bool,
    pub spot_dir: [f32; 3],
    pub cos_inner: f32,
    pub cos_outer: f32,
}

A point light in a grid’s local space, as handed to GpuRenderer::set_scene_lights. The facade transforms world-space roxlap_render::PointLights into each grid’s frame.

Fields

position: [f32; 3]

Grid-local position (voxel units).

radius: f32

Hard cutoff distance, world/voxel units.

color: [f32; 3]

Linear RGB, 0..1.

intensity: f32

casts_shadow: bool

spot_dir: [f32; 3]

SL — spot (cone) axis: unit direction the light shines along, in the same frame as Self::position (grid-local for the scene pass, world for the sprite pass). Ignored when Self::cos_outer is -1.0.

cos_inner: f32

SL — cosine of the inner cone half-angle (full brightness within it).

cos_outer: f32

SL — cosine of the outer cone half-angle (zero past it; soft between). -1.0 (180° cone) ⇒ a pure point light: the cone mask is skipped.

Trait Implementations

impl Clone for GpuLight

fn clone(&self) -> GpuLight

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for GpuLight

impl Debug for GpuLight

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GpuLight

fn eq(&self, other: &GpuLight) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
