A small project to fiddle around with GPU and Graphics programming, Built atop Zig and Mach

• Lookup up table (LUT) generation & application
• Dithering:
  • Bayer
  • Atkinson
  • [TODO] Floyd Steinberg
  • Blue Noise
• Nearest Neighbour Palette Lookup
• Grayscale

• Zig version 0.11.0-dev.3380+7e0a02ee2:
  • linux: https://ziglang.org/builds/zig-linux-x86_64-0.11.0-dev.3380+7e0a02ee2.tar.xz
  • windows-x86_64: https://ziglang.org/builds/zig-windows-x86_64-0.11.0-dev.3380+7e0a02ee2.zip
  • macos-x86_64 (Intel): https://ziglang.org/builds/zig-macos-x86_64-0.11.0-dev.3380+7e0a02ee2.tar.xz
  • macos-aarch64 (Apple Silicon): https://ziglang.org/builds/zig-macos-aarch64-0.11.0-dev.3380+7e0a02ee2.tar.xz

git clone --recurse-submodules -j8 http://github.com/undefinedDarkness/amnesia
cd amnesia
zig build run -- --help

Example: ./<binary> -d bayer -p palette.hex source.png

• Zig language & build system
• Mach for native webgpu bindings
• zig-clap for argument parsing
• stb for image reading / writing

Some of the math & generated images might not be completley accurate, This stuff can be kind of hard to tell
