    Ruffle is an open-source emulator for Adobe Flash Player, written primarily in Rust, and targeted at both desktop applications and web browsers via WebAssembly.

On the web side, Ruffle is embedded into pages or installed as a browser extension; in the desktop version, it can open .swf files directly or embed them in applications. Because it’s built with memory safety in mind, Ruffle helps avoid many of the security vulnerabilities that plagued classic Flash (buffer overflows, use-after-free, etc.). ...

    scene-oriented, flexible 3D engine (C++, Python, C#, Java)

    ...We consider the results of our GL3Plus RenderSystem as the gold standard. The respective shaders are generated by the RTSS component with per-pixel specular lighting. Therefore the legacy render systems naturally have differences due to the use of fixed-function. However, when rendering diffuse surface both produce pixel-perfect results. Simple, easy to use OO interface designed to minimise the effort required to render 3D scenes, and to be independent of 3D implementation i.e. Direct3D/OpenGL.
