This node is one of the three lights properties Nodes. PointLight defines a point light source at a fixed and stationary three-dimensional location. This light source is omni-directional. In other words, it illuminates the virtual world equally in all directions.
FILE FORMAT/DEFAULTS
PointLight {
on TRUE # SFBool intensity 1 # SFFloat color 1 1 1 # SFColor location 0 0 1 # SFVec3f
}
Basically, any of the three light nodes will define an illumination source that may affect any shapes or objects coming later in the scene graph. This, of course, will depend on the current lighting style. Keep in mind also that light sources will be affected by the current transformation. Also, any light node under a separator will not affect any objects outside that separator.
