Just released bc_crunch: a tiny (~700 LOC), C99 library for lossless BC1/BC4/BC3/BC5 compression.
One .c/.h pair, no deps, no malloc
GPU-ready output
Zigzag + delta + popcount/dictionary tricks
Tested
Perfect for games, procedural assets, streaming textures.

Revision is a non-profit event; however, that does not make us non-cost. Do you want to help us in realising one of the biggest participatory programming art events? Then we'd be excited to have you!

I finished writing the story of going to Revision this year. It ended up some 17,000 words long because I wanted to cover *everything*. And... I did! Eventually!

I put together a little site for looking up Vulkan enums by name, hex, or decimal :) I hunt for enums like this surprisingly often when developing, so I figured I'd share it around!

Here's an update on my small-voxel renderer, inspired by the look of games like Doom and Quake. The work I shared last year focused on handling simpler environment geometry. Since then, I've greatly expanded the scope of what I can depict in this art style. More info in thread.
