Hello,
Can anyone tell me who manufactures 3D cards based on the rendition chipset?
Thanks

Right now, there are no Renditon cards out. However, both the Creative
Labs 3D Blaster PCI and the Number 9 9FX Reality 532 will be using the
chip. But, even though the Rendition chip will be used as the Direct3d
reference chipset by Microsoft, it looks as though the 3Dfx
Interactive's Voodoo Graphics chip will have better performance and
support more features.
See: http://www.3dfx.com/ for more info. Most noteably, look at the 3D
Feature Comparison located at: http://www.3dfx.com/tech/bench.html

The articles in Computer *** World stated that the only card
currently in production using the Rendition 3D chipset was the 3D
Blaster PCI by Creative Labs. It is due out in August or so and should
run under $300. I'm already saving my money to snatch one of these up
as soon as it hits the shelf. Its supposed to make NASCAR 2 really fly.
Hope that gives you some info.

Well this information is just plain wrong. The 3Dfx does indeed support
trilinear filtering and lit polygons while it is the Rendition that does
not do either of these two features. It looks like CGW got the two
mixed up. This has been quite a hot topic over in the
comp.sys.ibm.pc.games.action newsgroup. The facts were set clear by a
former employee of 3Dfx. If your news server keeps posts around for a
while, check out the '3d Cards rated by speed, & MW2' thread.

Just to back up the other poster, the Voodoo graphics chipset does, in
fact, support
trilinear filtering and does lit polygons (although it doesn't do the
actual lighting
equation in hardware, since it's only a 2D rasterizer).
I wrote the hardware interface library for the Voodoo, so I'm pretty
confident I know
what I'm talking about.
Verite does NOT have t-li filtering, since this implies per-pixel
mapping which the
Verite does not have and Voodoo most assuredly does. You could also
check
www.3dfx.com and www.rendition.com.

On TRILINEAR Filtering:

I don't think that the term "trilinear" filtering can be used by anybody
because of potential trademark and/or patent issues, so often when you
see "LOD blending" or "advanced filtering", it's another name for
trilinear filtering.
Trilinear == interpolating between two groups of 4 texels based on a
weight derived from the fractional LOD between two mip map levels. In
essence it's a combination of bilinear blending and MIP map
interpolation, and it's sole purpose is to reduce MIP map "banding"
artifacts.
3Dfx supports this, although they don't call it such.
