Such artifacts also prevents closer inspection of Alliances Pseudo Bilinear texture filtering. Specifications promised a fine piece of 3D accelerator, press announcement and datasheet would make you think you cannot go wrong. Its promise of single cycle bump-mapping was not fulfilled. Let me just say if often exposes problems in the style of Trident 3DImage. And since AT3D does not use system memory there is with 4 MB little hope for true color rendering at higher resolutions. Samples are planned for April with volume shipments planned for June

Big numbers, triangle setup, free per-pixel perspective correction, all the texture formats and blending operations supported, bit video engine and bit memory bus. If it could work properly with at least similar speeds as measured here those chips with prices as ay25/at3d as 20 bucks, then it could find happy buyers. Usually AT3D fails to deliver on the promise of 30 frames per second at xx Alpha blending is usually done with stipple patterns and quality of bilinear filter escapes me because of all the warping.

Results Performance is not the worst, but it is not impressive either. Except for historical information contained herein, the above constitutes forward looking statements; actual results could differ materially from those projected in the forward looking statements as a result of the factors set forth in the Company’s most recent Annual Report on Form K and Quarterly Report on Form Q, respectively, each of which is filed with the Securities and Exchange Commission and available through the Company’s home page: And then you fire up the card, play games and everything is broken.


Its promise of single cycle bump-mapping was not fulfilled. But only after you see AT3D in action, you will know how much broken can things be.

Specifications promised a fine piece of 3D accelerator, press announcement and datasheet would make you think you cannot go wrong. Alliance will continue to provide innovative, industry leading solutions for the multimedia market.

Alliance promised all-in-one solution for new multimedia age. However, at such depth only palletized textures may be blended “properly”.

The Company designs, develops, and markets its products to the desktop and portable computing, networking, telecommunications and instrumentation markets. Frankly, I have no idea, datasheet also mentions Z-buffer compression, but the card does not behave like if it has more memory than others. I take abandonment of those chips as another proof of how broken the design was. The architecture is optimized to provide fast frame rates to ensure maximum interactivity.

Alliance Press Release

Their ProMotion line of 2D graphics allaince did not fail, but were not exactly famous either. Alliance did not give up on 3d after this disaster and announced another bit architecture: Logo of Alliance is on many memory chips of the nineties.

Company Information Alliance Semiconductor Corporation is a leading promotlon supplier of high performance memory and at52/at3d intensive logic products. Technical specs says that Alliance chips got a special 64 bit bus for fast communication with Rush.


Gouraud shading is done full speed and geometry looks perspectively ok. True color textures are full speed and true color buffer is also possible with a small performance penalty. In summer of the company ended all support for graphics technologies and continued business only with memory and embedded electronics.

Even specular highlights are done via stipple mask. Alliance got more attention from gamers when their graphics cores were chosen for Voodoo Rush boards supporting 3D only chipset of 3Dfx.

Additional Company information can be found on our home page: It reminds me of certain quadrilateral texturing chip trying to render triangles. This engine performs geometry setup promotionn hardware promohion enables the main CPU to perform more critical tasks. This controller incorporates the fast bit 2D engine while simultaneously integrating TV output with a three line flicker filter and downscaler.

Normally such image quality would disqualify the card from benchmarks, but just to get some idea of it’s performance I measured few games that were recognizable. They are still alive today, albeit they moved away from semiconductors.

All texture formats from palletized up to are supported.
