High quality texture compression comparison
Sunday, June 11, 2006 | Permalink

I've been asked to put up comparison screenshots for people to see who don't have the hardware to run the demo. So here they are:

DXT1 4pp
YCbCr 4.5bpp
YCbCr 6bpp
RGB 24bpp

So if i understand correctly , the quality of the texture stays the same, but less bits are used to store the data (in DXT1, YCbCr ...) Very cool

Well, not exactly.

They all degrade quality in order to
decrease the size of the image.

The difference between them is the quality/size
ratio, and different types of tricks used to make
the degraded quality less visible.

Thx for explanation

I don't think this comparison is 100% fair since the original image is such poor quality that some compression artifacts may not be visisble.

There's nothing wrong with quality of the source image; however, it's zoomed in so that you can compare the compression artifacts better. When you're zoomed out even DXT1 will look fine.
