OpenGL
OpenGL is a standard specification defining a cross-language, cross-platform API for writing applications that produce 2D and 3D computer graphics. The interface consists of over 250 different function calls which can be used to draw complex three-dimensional scenes from simple primitives. OpenGL...

Development History

The Glaze3D family of cards were developed in several generations, beginning with the original Glaze3D "400" with multi-channel RDRAM instead of internal eDRAM. This was offered only as IP but with no takers. Bitboys revised the design and decided to have it manufactured themselves, in cooperation with Infineon Technologies, the chip fabrication arm of Siemens. They came up with a new Glaze3D pitched for release in Q1, 2000. The card promised extremely high performance compared to contemporary consumer GPUs. As bug-hunting, validation and manufacturing problems delayed the launch, new features became necessary and a DX7 variant with built-in hardware Transform & Lighting was announced, but never appeared.

The GPU was later redesigned under a new codename, Axe, to take advantage of DirectX 8 and compete with a developing competition. The new version sported such features as an additional 3 MB of eDRAM
EDRAM
eDRAM stands for "embedded DRAM", a capacitor-based dynamic random access memory integrated on the same die as an ASIC or processor. The cost-per-bit is higher than for stand-alone DRAM chips but in many applications the performance advantages of placing the eDRAM on the same chip as the processor...

Fillrate

, as well as offering a programmable vertex shader and widened internal memory bus. The new card was to have been released as Avalanche3D by the end of 2001.

The third development, codenamed Hammer, started development as Axe lost viability toward the end of 2001. This new card was to be a high-end DirectX 9 part, offering new features such as occlusion culling, improved rendering performance and various other innovations. This version, like the ones before it, never shipped commercially.

Bitboys turned to mobile graphics and developed an accelerator licensed and probably used by at least one flat panel display manufacture, although it was intended and designed primarily for higher-end handhelds. Later on ATI bought Bitboys for an extra research and development unit, so as of 2008 Bitboys was owned by AMD. In 2009, Bitboys was transferred to Qualcomm.

Performance Claims

The Glaze3D family was well-known for the bold performance claims that were associated with it. The low-end 1200 model was purported to achieve a fillrate of 1.2 billion

(very low performance GPUs of 2002 vintage), while its claimed performance would place it at the same level as the GeForce 3 Ti 500 or Radeon 8500 (high-end GPUs from 2000-2001). To compound matters, the cards' specifications were later updated to nearly double their original performance levels.

While the Glaze3D 1200 was supposed to achieve unheard of performance in video games, it was claimed that the 2400 and 4800 models would each be substantially more powerful in turn. Using two and four GPU configurations respectively, and including an additional geometry accelerator on the 4800, the higher-end Glaze3D cards were to be aimed at the very highest end of the video gaming market.
