Fudge is a 3D graph visualization tool that uses the force-directed technique of drawing graphs. We can consider a graph as a physical system where every vertex of a graph is a particle exerting a repelling force on every other vertex, and any two vertices connected by an edge are pulled towards each other by a spring force. Over time, the system settles into a stable configuration which results in an aesthetically pleasing visualization of the graph.

Install dependencies (Emscripten, GLFW3, GLEW)

sudo apt-get install libglew-dev emscripten libglfw3 libglfw3-dev

To build the OpenGL version, run

make && ./fdg

To build for WebGL, run

make -f Makefile_emscripten

Emscripten will generate index.js, index.wasm under the build directory. The webpage can be opened at build/index.html.
