NAME

gt − double buffered 24-bit SBus color memory frame buffer and graphics accelerator

DESCRIPTION

gt is a 24-bit SBus-based color frame buffer and graphics accelerator.  The frame buffer consists of 108 video memory planes of 1280×1024 pixels including 24-bit double buffering, 16 alpha/overlay planes, 24 z-buffer planes, 10 window id planes, 8 fast clear planes, and 2 cursor planes.  It provides the standard frame buffer interface defined in fbio(7), paired with microcode which can be downloaded using gtconfig (1M).  Application acceleration is achieved via the Pixrect/Pixwin and SunPHIGS Application Programmer Interfaces (APIs).
