ModelLight class final
A punctual light, decoded from KHR_lights_punctual or held for a
writer to encode into it — fmt-28's own row.
Values, not watts. intensity is exactly the number the extension
carries — lux for ModelLightType.directional, candela for
ModelLightType.point/ModelLightType.spot — and this class does no
unit conversion of its own; a caller feeding it to a renderer with a
different convention does that conversion at the seam, not here.
Constructors
- ModelLight({required ModelLightType type, Vector3? color, double intensity = 1.0, double? range, double innerConeAngle = 0.0, double? outerConeAngle, String? name})
Properties
- color → Vector3
-
Linear RGB, the same convention every other colour in this package
(
SurfaceMaterial.baseColorexcepted, which is non-linear as authored) already uses for a light or a material factor.final - hashCode → int
-
The hash code for this object.
no setterinherited
- innerConeAngle → double
-
Spot-only: the angle, in radians, inside which a spot is at full
intensity. Meaningless for the other two types and kept anyway,
since ModelLightType.point/ModelLightType.directional never read
it and a writer only emits it for a spot.
final
- intensity → double
-
Lux for ModelLightType.directional, candela otherwise. The
specification's own default when a file omits the key.
final
- name → String?
-
final
- outerConeAngle → double
-
Spot-only: the angle, in radians, past which a spot contributes
nothing. Defaults to the specification's own quarter turn over four —
45 degrees.
final
- range → double?
-
Distance at which a point or spot light stops contributing, or null
for unbounded — the specification's own default when the key is
absent, kept as
nullrather than folded into a number so a writer can tell "the file said no limit" from "the file said a very large number" and omit the key again rather than inventing one.final - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- type → ModelLightType

Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

A string representation of this object.

operator ==(
Object other) → bool -
The equality operator.
