The PointLight node specifies a point light source at 3D location in the local coordinate system. A point source emits light equally in all directions; that is, it is omni-directional. PointLights are specified in their local coordinate system and are affected by parent transformations.

See "Concepts - Light Sources" for a detailed description of the ambientIntensity, color, and intensity fields.

A PointLight may illuminate geometry within radius (>= 0.0) meters of its location. Both radius and location are affected by parent transformations (scale radius and transform location).

A PointLight's illumination falls off with distance as specified by three attenuation coefficients. The attenuation factor is 1/(attenuation[0] + attenuation[1]*r + attenuation[2]*r^2), where r is the distance of the light to the surface being illuminated. The default is no attenuation. An attenuation value of 0 0 0 is identical to 1 0 0. Attenuation values must be >= 0.0. Renderers that do not support a full attenuation model may approximate as necessary. See "Concepts - Lighting Model" for a detailed description of VRML's lighting equations.
