Enum ShadowEntry 

pub enum ShadowEntry {
    Atlas2D {
        view_proj: Mat4,
        atlas_index: i32,
    },
    Cube {
        face_view_projs: Box<[Mat4; 6]>,
        cube_array_index: i32,
        light_pos: Vec3,
        far_plane: f32,
    },
}

Shadow data computed by a shadow strategy for a single light.

Two variants reflect the two atlas binding surfaces:

• ShadowEntry::Atlas2D — directional / spot, sampled with one view-projection matrix against a texture_depth_2d_array.
• ShadowEntry::Cube — point lights, sampled directionally against a texture_depth_cube_array. The CPU-side per-face matrices are kept on the entry so the strategy can rebuild bind data without re-running its source flow.

Cube is boxed to keep the enum size close to Atlas2D (most lights in a typical scene are directional / spot).

Variants

Atlas2D

Directional / spot shadow stored in the 2D depth-array atlas.

Fields

view_proj: Mat4

Light’s view-projection matrix used to sample the shadow atlas.

atlas_index: i32

Layer index inside the 2D atlas.

Cube

Point-light omnidirectional shadow stored in the cubemap atlas.

Fields

face_view_projs: Box<[Mat4; 6]>

Per-face view-projection matrices in [crate::math::CubeFace::ALL] order ([+X, -X, +Y, -Y, +Z, -Z]).

cube_array_index: i32

Layer index inside the cube-array atlas (the GPU consumes cube_array_index * 6 + face_index to address a face).

light_pos: Vec3

World-space light position. The shader uses this to compute the fragment-to-light direction it samples the cubemap with.

far_plane: f32

Light’s effective range — the perspective far plane used when rendering the six faces. The shader recomputes the non-linear depth value with this constant to compare against the sampled depth.
