Enum LightType

pub enum LightType {
    Ambient,
    Directional {
        direction: Vec3D,
    },
    Point {
        position: Vec3D,
    },
}

Type of light, determines how the normal of a face affects its illumination

Variants

Ambient

Lights the entire scene equally. It’s good to have at least one of these so your models don’t go completely dark.

Directional

Lights the scene from a specific direction. A surface facing the specified direction will be lit with the most intensity and a surface facing away from the direction will be lit with the least intensity or no intensity at all

Fields

direction: Vec3D

The direction the light is pointing

Point

Light comes from a postion in 3D space. This light type does not currently dissipate over distance, so can be represented with a single position

Fields

position: Vec3D

The position from which the light emanates

Trait Implementations

impl Clone for LightType

fn clone(&self) -> LightType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LightType

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

Formats the value using the given formatter.

impl PartialEq for LightType

fn eq(&self, other: &LightType) -> 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.
