Struct LitSettings

pub struct LitSettings {
    pub light_direction: Vec3,
    pub camera_position: Vec3,
    pub fog_color: Color,
    pub fog_start: f32,
    pub fog_end: f32,
    pub ambient: f32,
}

Fields

light_direction: Vec3

World-space direction from a surface toward the directional light.

camera_position: Vec3

fog_color: Color

fog_start: f32

fog_end: f32

ambient: f32

Implementations

impl LitSettings

pub fn sanitized(self) -> LitSettings

Normalize the light and bound user-supplied settings once per material begin. Nonfinite settings use their defaults; a zero light direction is ambient-only.

pub fn shade_vertex(self, position: Vec3, normal: Vec3, color: Color) -> Color

Shade an already world-transformed position and normal, retaining alpha.

Pass settings through Self::sanitized before a batch so the light is normalized once. Normals may be unnormalized or zero. Reversed/coincident fog bounds become a 0.001-unit transition starting at fog_start.

Trait Implementations

impl Clone for LitSettings

fn clone(&self) -> LitSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LitSettings

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for LitSettings

fn default() -> LitSettings

Returns the “default value” for a type.

impl PartialEq for LitSettings

fn eq(&self, other: &LitSettings) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for LitSettings

impl StructuralPartialEq for LitSettings
