Struct WorldShadowCtx 

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

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

origin: [f32; 3]

cols: [[f32; 3]; 3]

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.
