SUBROUTINE MULTIM

Description

The multimap subroutine reorganizes the color map as 16 small independent maps. Only one of these small maps can be active, or current, at a time, and only the least significant bits in the frame buffer are passed through the current map.

On the 24-bit High-Performance 3-D Color Graphics Processor, these small maps are each 8-bit color maps having 256 entries. On the 8-bit High-Performance 3-D Color Graphics Processor, the maps are each 4-bit color maps having 16 entries.

After the multimap subroutine is called, the reorganization into multiple independent maps does not take effect until the gconfig subroutine is called.

Notes:
  1. The operation of this subroutine for the Supergraphics Processor Subsystem is modified. (See "Understanding the Adapter".)
  2. This subroutine cannot be used to add to a display list.

Implementation Specifics

This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.

The POWER GXT1000 adapter does not support the multimap subroutine.
