Name

PSBRFI − Sets the back reflectance index value. 

Operating States: PHOP, ∗, STOP, ∗
PHIGS PLUS function
Creates a structure element

Syntax

PSBRFI (BRFI)

Argument       Data Type      Access   Description
---------------------------------------------------------------------------
BRFI           Integer        Read     Back reflectance index
---------------------------------------------------------------------------

Description

PSBRFI sets the back reflectance index value.  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 back reflectance index element. 

During structure traversal, Digital PHIGS sets the current back reflectance index entry in the PHIGS traversal state list to the specified value.  Digital PHIGS uses this value when displaying subsequent back-facing portions of area primitives. 

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

Digital PHIGS Version 3.1 does not support this function.
