X3D Reference

PointLight

PointLight

PointLight is a single light source that illuminates outwards in all directions. Light illuminates all geometry and is normally scoped to illuminate peers and children nodes within the scene graph hierarchy Lights have no visible shape themselves and shine through occluding geometry.

The PointLight node belongs to the Lighting component and its container field is children. It is available since X3D version 3.0 or later.

Hierarchy

Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

SFBool [in, out] global TRUE

Global lights illuminate all objects within their volume of lighting influence. Scoped lights only illuminate objects within the same transformation hierarchy.

SFBool [in, out] on TRUE

Enables/disables this light source.

SFFloat [in, out] intensity 1 [0,1]

Brightness of direct emission from the light.

SFFloat [in, out] ambientIntensity [0,1]

Brightness of ambient (nondirectional background) emission from the light.

SFVec3f [in, out] attenuation 1 0 0 [0,∞)

Constant, linear-distance and squared-distance dropoff factors.

SFVec3f [in, out] location 0 0 0 (-∞,∞)

Position of light relative to local coordinate system.

SFFloat [in, out] radius 100 [0,∞)

Maximum effective distance of light relative to local light position, affected by ancestor scaling.

SFFloat [in, out] shadowIntensity 0 [0,1]

Intensity of shadow.

SFFloat [in, out] shadowBias 0.005 [0,1]

The shadowBias value controls the visibility of shadow acne.

SFInt32 [ ] shadowMapSize 1024 [0,∞)

Size of the shadow map in pixels, must be power of two.
