(require "xg.3d-lgt.lsp") (SEND <lgt> :SET-SPHERICAL-LOCATION [ :DISTANCE <flo:distance> ] [ :AZIMUTH <flo:azimuth> ] [ :ALTITUDE <flo:altitude> ] )
Set a light's location relative to a sphere around its target point. This is useful when moving a light around a single object of interest.
The :DISTANCE/:AZIMUTH/:ALTITUDE settings are stored in the light's property list. However, changing them directly will not update the light's position. (This is simply because it's not a needed feature yet. It wouldn't be hard to do.)
