Texture mapping
The Stellar GS workstation family consisted of the GS1000 and GS2000 models. After Stellar merged with Ardent to form Stardent they were sold as the ST1000 and ST2000 models. The GS2000 CPU supported four threads or streams of execution for a total of 20 MIPS and had a vector coprocessor capable of 80 MFLOPS. 16 to 128MB of system memory was supported. 64MB of memory was typical. The four threads were implemented using a Barrel processor design similar to that used in the CDC 6000 series and the Denelcor HEP. The GS2000 graphics subsystem supported interactive 3D rendering at rates of up to 120,000 Gouraud-shaded triangles per second and 600,000 short vectors per second. Texture mapping and antialiasing with an accumulation buffer were also supported. The CPU and graphics system shared the system memory and vector coprocessor.
