Struct WorldShadowCtx 

pub struct WorldShadowCtx<'a> {
    pub occluder: &'a dyn WorldOccluder,
    pub origin: [f64; 3],
    pub cols: [[f32; 3]; 3],
    pub voxel_world_size: f32,
}

XS.1 — per-grid context for a cross-scene shadow query: the scene-wide WorldOccluder plus the current grid’s local→world transform, so a grid-local shadow ray (the frame shade_dynamic works in) can be lifted to world space before the scene-wide test. cols[i] is the world-space image of grid-local axis i (the grid rotation’s columns); origin is the grid’s world origin.

Fields

occluder: &'a dyn WorldOccluder

The scene-wide occlusion oracle every lifted shadow ray is tested against.

origin: [f64; 3]

The current grid’s world-space origin — the translation part of its local→world transform (added to rotated positions; directions skip it). SC.2 — f64: kept full-precision so a scaled grid’s large world coordinates survive the lift (see WorldOccluder).

cols: [[f32; 3]; 3]

Columns of the grid’s local→world rotation: cols[i] is the world-space image of grid-local axis i. Kept orthonormal (pure rotation) — the grid’s voxel scale rides in voxel_world_size, not folded into the columns.

voxel_world_size: f32

SC.2 — the caster grid’s voxel_world_size (world units per voxel). The shade works in the grid’s voxel frame, so lifting a shadow ray to world scales the local position and direction by this (a voxel offset becomes vws world units). 1.0 for an unscaled grid (byte-identical to XS.1) and for already-world-space sprites.

Implementations

impl<'a> WorldShadowCtx<'a>

pub fn identity(occluder: &'a dyn WorldOccluder) -> Self

Identity transform — for shading already in world space (sprites): the grid-local ray IS the world ray.

Trait Implementations

impl<'a> Clone for WorldShadowCtx<'a>

fn clone(&self) -> WorldShadowCtx<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
