Offset

Attenuation

Factors describing the attenuation of light intensity over distance.

public Attenuation Attenuation { get; set; }

Property Value

Attenuation

Offset

The offset from AttachedTo in its local coordinate system. Ignored while AttachedTo is null.

public Vector3 Offset { get; set; }

Property Value

Vector3

Position

The position of the light source in world space.

public DoubleVector3 Position { get; set; }

Property Value

DoubleVector3

Remarks

While AttachedTo is set, this is recalculated from Offset by OmegaEngine.Graphics.LightSources.PointLight.UpdatePosition() and setting it has no lasting effect.

Range

The maximum distance at which the light source has an effect.

public float Range { get; }

Property Value

float

RenderAsDirectional

Shall this light source be converted to a pseudo-directional source for each individual PositionableRenderable before rendering?
