Struct dae_parser::PointLight

pub struct PointLight {
    pub color: Box<[f32; 3]>,
    pub constant_attenuation: f32,
    pub linear_attenuation: f32,
    pub quadratic_attenuation: f32,
}

Describes a point light source.

The position of the light is defined by the transform of the node in which it is instantiated.

The constant_attenuation, linear_attenuation, and quadratic_attenuation are used to calculate the total attenuation of this light given a distance. The equation used is:

A = constant_attenuation + Dist * linear_attenuation + Dist^2 * quadratic_attenuation

Fields

color: Box<[f32; 3]>

Contains three floating-point numbers specifying the color of the light.

constant_attenuation: f32

The constant term in the attentuation equation, see PointLight.

linear_attenuation: f32

The linear term in the attentuation equation, see PointLight.

quadratic_attenuation: f32

The quadratic term in the attentuation equation, see PointLight.
