The GLINT family of graphics processors dominates the professional 3D market on the PC. GLINT GMX is the first graphics chipset to accelerate the full 3D geometry pipeline in hardware to significantly increase the performance of applications such as mechanical, industrial and architectural design, animation, multimedia and 3D web authoring, visualization and visual simulation.

The GLINT GMX family of chipsets delivers the ultimate in high-end workstation graphics performance by integrating full 3D geometry acceleration with scalable rasterization processing into a seamless professional graphics solution.

The GLINT GMX 1000 and GLINT GMX 2000 chipsets utilize a hardwired GLINT Gamma geometry processor and one or two GLINT MX rasterizer engines, together with a GLINT VGA, for complete, high-precision, 32-bit, professional 2D and 3D graphics acceleration in AGP or PCI systems.

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