is a 24-bit SBus-based color frame buffer and graphics accelerator.
|
|
The frame buffer consists of 108 video memory planes of 1280\(mu1024
|
|
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
|
|
.BR fbio (4S),
|
|
paired with microcode which can be downloaded using
|
|
.B gtconfig (8).
|
|
Application acceleration is achieved via the Pixrect/Pixwin and SunPHIGS
|
|
Application Programmer Interfaces (APIs).
