Drawn with Pencil2D and MyPaint, animated using meshes in LÖVE (Lua language), I also made some tests in C with libSDL, but it is probably faster to prototype in Lua with LÖVE, and then add FFI libs for compute intensive part (in these cases light computations, GL is used for rendering), or port it to c+SDL at second time, when algorithms are validated. All used software are 100% FOSS used on a GNU/Linux system.
This one use simply a mesh on a picture, and deform them using circular motions, as I done in TIC-80 in July 2021. You can get all the sources and pictures and the whole LÖVE thing packaged: https://framagit.org/popolon/reforest
