Expand description
A light that emits light in a given direction from a central point.
Behaves like a point light in a perfectly absorbent housing that
shines light only in a given direction. The direction is taken from
the transform, and can be specified with Transform::looking_at
.
Fields§
§color: Color
§intensity: f32
§range: f32
§radius: f32
§shadows_enabled: bool
§shadow_depth_bias: f32
§shadow_normal_bias: f32
A bias applied along the direction of the fragment’s surface normal. It is scaled to the shadow map’s texel size so that it can be small close to the camera and gets larger further away.
outer_angle: f32
Angle defining the distance from the spot light direction to the outer limit
of the light’s cone of effect.
outer_angle
should be < PI / 2.0
.
PI / 2.0
defines a hemispherical spot light, but shadows become very blocky as the angle
approaches this limit.
inner_angle: f32
Angle defining the distance from the spot light direction to the inner limit
of the light’s cone of effect.
Light is attenuated from inner_angle
to outer_angle
to give a smooth falloff.
inner_angle
should be <= outer_angle
