Struct ShadowBias 

pub struct ShadowBias {
    pub constant: f32,
    pub slope_scale: f32,
    pub normal_offset: f32,
}

Configurable shadow bias combining constant, slope-scaled, and normal offset.

Fields

constant: f32

Constant depth bias (added directly to the depth comparison).

slope_scale: f32

Slope-scaled bias (multiplied by the depth slope).

normal_offset: f32

Normal offset (offsets the shadow lookup along the surface normal).

Implementations

impl ShadowBias

pub fn new(constant: f32, slope_scale: f32, normal_offset: f32) -> Self

pub fn compute(&self, depth_slope: f32, _cos_angle: f32) -> f32

Compute the effective bias given the depth slope and surface angle.

pub fn normal_offset_vec(&self, normal: Vec3) -> Vec3

Compute the world-space offset along the surface normal.

pub fn apply_normal_offset(&self, position: Vec3, normal: Vec3) -> Vec3

Apply normal offset to a world position before shadow lookup.
