Welcome to the metaballs-glfw wiki!

Project plan:

Rendering

1. Render a primitive shape
2. Mathematical definition of a single metaball's potential field.
3. Define the potential field isosurface in code
4. Define the additive potential field isosurface (multiple balls)
5. Implement the marching cubes algorithm as a geometry shader
6. Render a single metaball with marching cubes
7. Render multiple metaballs with interacting potential fields

Physics

1. Collision compute shader or external physics library
2. Gravity
3. Sphere-sphere collision
4. Sphere-cube collision
5. Build environment using cubes
