Compression screenshot

That's the output of my texture compressor running on an emulator, compared to the original. It also works on the hardware. The result is still rather blocky, but I have an idea of how to make it look better... hopefully not requiring a small cluster to do the calculations...

Anyway, this is the first non-trivial image compressor I've ever done. It's slow and the results are not that great yet, but I am feeling pretty good about it. According to my git logs, I started this last Tuesday evening. If I keep getting into these side projects, I'm never going to get any work done on that simple little game I was trying to write :P

Wow, sweet. Blatent use of GIMP ftw. :P

Maybe there's some sort of hardware-based blur you can do? Very light would probably be jsut perfect.

Unfortunately, the hardware doesn't support any kind of pixel shading. Right now I'm looking at taking a second pass over the image, and brute force searching the palette for a better match on any block with too high an error. It's looking pretty slow, and I'm not even sure it's going to improve anything.

Either way I'm declaring victory, since I think an 8x resolution increase outweighs the compression artifacts I have now :)
