rouse - cross-platform interactive animation engine

Flash Player is dead and I still want to make interactive animations. This is my replacement.

The main library is written in C and there's Lua bindings on top of that. It's confirmed to run on Linux, Windows and, thanks to Emscripten, in just about any browser you can get your hands on, even on mobile devices. It should also work natively on macOS, iOS and Android, but I haven't gotten around to trying that.

Check out a sample animation here: https://askmeaboutlo0m.github.io/rouse-sampleanim/index.html

There's a few sub-projects here:

• rouse-core contains the main library.

• rouse-lua has the Lua bindings.

• rouse-tools is a collection of miscellaneous scripts.

This project uses CMake. You need version 3.14 or newer.

Perl version 5.20 is required for several code generation scripts involved. It should come with most Linux distributions and macOS.

You need SDL2 and SDL2_image. Those should be available in your package manager. You also need cglm, which you probably need to build from source.

I've only tried building this on Linux with gcc and clang. It should work on other systems as well, but probably needs adjustments.

Check out the metamake script, it's what works for me. It uses Ninja as the CMake generation target, so either install that (via your package manager ideally) or replace it with make calls. It supports the following build modes:

• metamake debug to build for Linux in debug mode.

• metamake release for Linux release mode.

• metamake emscripten to build a browser version. You need Emscripten and set the EMPREFIX environment variable to where you installed cglm.

• metamake windows to cross-compile to Windows. This requires Docker, but nothing else, as it'll bootstrap itself.

This thing is still severely undercooked. Docs are missing.
