Description

pset_refl_model sets the reflectance model Digital PHIGS uses to display front-facing portions of area primitives.  Depending on the current edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer.  The pointer then points to the new set reflectance model element. 

During structure traversal, Digital PHIGS sets the current reflectance model entry in the PHIGS traversal state list to the value associated with the element.  When the current reflectance model ASF entry in the traversal state list is INDIVIDUAL, Digital PHIGS uses this value to display front-facing portions of subsequent area primitives.  If the specified reflectance model value is not available on a workstation, Digital PHIGS uses value 1. 

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element.
