New high quality texture compression demo
Friday, June 2, 2006 | Permalink

I've uploaded a new demo that shows up a high quality texture compression method. Awesome artwork!!! ... no actually it's just a textured quad, but the point is to show the quality difference between different methods.

Looks very good. Should become the new compression standard :-)

I think this method can deal with HDR, too.

Probably. In my HDR demo I did L16 + DXT1 (20bpp). It would probably be possible to do L16 + 3Dc, which could produce better quality at full resolution (24bpp) or slightly better performance at half res chrominance (essentially 17bpp).

I transform the RGB to {log2(Y), 0.114 * B / Y, 0.229 * R / Y}. logY is stored in L16, B & R are stored in XRGB8 or GR16. It gets 24bpp with good quality.

Can you write an ATI 9600 compatible version?
It's possible?

Thanks.

I've uploaded a version that allows it to run on all PS2.0 cards. It will use DXT1/DXT5 which looks worse than ATI1N/ATI2N but better than plain DXT1. On X1K cards you can use both DXT and 3Dc modes.
