Tool, that allows You to write simple procedural graphics in Lua.

See gallery

This project depends on: lua-jit (5.1), sdl3 and sdl3-ttf (and all of their dependencies) - most of which should be available in Your package manager. pkg-config is used to search for them.

Building is as simple as running make in root of the project.

This will generate dgfx executable. WARNING - this executable depends on everything in resources directory at runtime.

WIP - use dgfx --help, examples and see config header for now :3

At this point I think I've optimized it as much as possible, without making the project too complicated.

The next step would probably involve transpiling lua into actual shader language, to make use of GPU. I won't be doing that (for now :3).

I've experimented with ffi to eliminate memory copying, but it made program much slower for some reason. Leaving everything to C compiler and lua-jit resulted in the best performance.

This project is a toy - a challenge to create a fast lua -> C integration - not a serious project with many usecases.
