Struct OmniShadowMap 

pub struct OmniShadowMap {
    pub faces: [ShadowMap; 6],
    pub light_position: Vec3,
    pub radius: f32,
    pub resolution: u32,
}

Shadow map for point lights using a 6-face cubemap layout.

Fields

faces: [ShadowMap; 6]

Six shadow map faces: +X, -X, +Y, -Y, +Z, -Z.

light_position: Vec3

The light’s position.

radius: f32

The light’s radius (far plane).

resolution: u32

Resolution per face.

Implementations

impl OmniShadowMap

pub fn new(resolution: u32, light_position: Vec3, radius: f32) -> Self

pub fn update_matrices(&mut self)

Recompute the view-projection matrices for all six faces.

pub fn set_position(&mut self, pos: Vec3)

Update the light position and recompute matrices.

pub fn clear_all(&mut self)

Clear all faces.

pub fn select_face(direction: Vec3) -> CubeFace

Determine which cube face a direction vector maps to.

pub fn is_in_shadow(&self, world_pos: Vec3, bias: f32) -> bool
