The scaleable GLINT DMX chipset family provides affordable, high-precision, 32-bit workstation graphics acceleration capable of running at screen resolutions up to 2Kx2K for applications such as mechanical, industrial and architectural design, animation, multimedia and 3D web authoring, visualization and visual simulation.

GLINT DMX integrates cost-effective geometry setup processing with scalable rasterization performance into a seamless professional graphics solution.

The GLINT DMX 1000 and GLINT DMX 2000 chipsets utilize a hardwired GLINT Delta geometry setup processor and one or two GLINT MX rasterizer engines, together with a GLINT VGA, for completely seamless professional 2D and 3D graphics acceleration in PCI systems.

The GLINT DMX chipsets delivers 100% acceleration of the OpenGL 1.1 rasterization pipeline, and GLINT is certified by the leading workstation applications such as Pro/ENGINEER, I-DEAS, SOFTIMAGE3D and 3D Studio MAX.
