The last thing I can deduce from such awful gallery is per polygon mip-mapping with unstable mip selection. Let me guess, they split the bit bus into two. All features supported by the engine can be used simultaneously, with only one rendering pass required for any combination. They are still alive today, albeit they moved away from semiconductors. Alliance got more attention from gamers when their graphics cores were chosen for Voodoo Rush boards supporting 3D only chipset of 3Dfx. Texturing however, is so warped it turns your accelerated games into chaos barfed all over your display. 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.

It sets memory clock 60 MHz and it is reasonable to expect clock of the nm chip to be synchronous. Such artifacts also prevents closer inspection of Alliances Pseudo Bilinear texture filtering.

I take abandonment of those chips as another proof of how broken the design was. This controller incorporates the fast bit 2D engine while simultaneously integrating TV output with a three line flicker filter and downscaler.

Please do not send technical questions or requests to webmaster alsc. Conclusion Well, that was fast. Reality check AT3D arrived in summer and Alliance was showing it off as a true second generation 3d accelerator.


They are still alive today, albeit they moved away from semiconductors. That is the fun of early 3d accelerators.

All features supported by the engine can be used simultaneously, with only one rendering pass required for any combination. The architecture is optimized to provide fast frame rates to ensure maximum interactivity. Alpha blending is usually done with stipple patterns and quality of bilinear filter escapes me because of all the warping. The Company designs, develops, and markets its products to the desktop and portable computing, networking, telecommunications and instrumentation markets.

The chip also supported odd sizes of 1. Alliance did not give up on 3d after this disaster and announced another bit architecture: In summer of the company ended all support for graphics technologies and continued business only with memory and embedded electronics.

Even if the basics of textured polygons worked properly the AT3D would not get high image quality marks. Technical specs says that Alliance chips got a special 64 bit bus for fast communication with Rush.

Alliamce is with last official driver which Alliance still offers on their web for download. Samples are planned for April with volume shipments planned for June Even specular highlights are done via stipple mask. Alliance promised all-in-one solution prromotion new multimedia age.

Alliance ProMotion AT3D

Big numbers, triangle setup, free per-pixel perspective correction, all the texture formats and blending operations supported, bit video engine and bit memory bus. I was too disgusted to measure games again, though. Ar3d me just say if often exposes problems in the style of Trident 3DImage.


The ProMotion core meets the most demanding 2D and video requirements, featuring a fast bit internal drawing engine; DVD and live video input port VMI ; video playback acceleration, including full bilinear filtering; and hardware gamma correction and chroma correction.

They sure feel better than MX, but I am allince benchmarking 2D. This engine performs geometry setup in hardware which enables the main CPU to perform more critical tasks. AT3D delivers true state-of-the-art 3D acceleration, including on-chip hardware geometry setup, to bring the fast frame rates of console gaming to the Prootion platform.

Send all questions and comments regarding this site’s condition to webmaster alsc. If it could work properly with at least similar speeds as measured here those chips with prices as low as 20 promotiin, then it could find happy buyers.

The Alliance multimedia accelerators are supported by a robust driver suite which has undergone extensive testing. Perspective correction might have been very well implemented without performance penalty, but somehow at the end all important textures are not adjusted. Alliance manufactures many of its products using advanced 0. All other trademarks are property of their respective holders.
