RELATIVE_TO_PARENTS

RELATIVE_TO_ABSOLUTE

void setReferenceFrame(ReferenceFrame rf)

Set the light sources's ReferenceFrame, either to be relative to its parent reference frame, or relative to an absolute coordinate frame. RELATIVE_TO_PARENTS is the default. Note: setting the ReferenceFrame to be RELATIVE_TO_ABSOLUTE will also set the CullingActive flag on the light source, and hence all of its parents, to false, thereby disabling culling of it and all its parents. This is neccessary to prevent inappropriate culling, but may impact cull times if the absolute light source is deep in the scene graph. It is therefore recommend to only use absolute light source at the top of the scene.
