Subset


Description

Subset takes a collection of elements (objects or subcomponents) and determines the subset of elements that match the filter requirements. Softimage uses the Subset callback to filter the nodes displayed in an explorer view, and to filter subcomponents selected in a 3D view. If you don't provide a Subset callback, Softimage calls Match on each object to be filtered.
