# Ten Minute Physics in Unity

Implementations in Unity of the YouTube channel Ten Minute Physics.

## 1-2. Cannon ball

Simulate a bouncy cannon ball.

## 3. Billiard

Simulate billiard balls with different size and mass. Watch this YouTube video for examples:

## 4. Pinball

Simulate a pinball game.

Simulate beads attached to a circular wire.

## 6. Pendulums

Simulate the chaotic behavior of pendulums with as many arms as you want and where each arm can have different mass. With many arms you get a rope or hair! Watch these YouTube videos for examples:

## 8. Interaction

Catch and throw a ball with your mouse.

## 10. Soft body physics

Simple unbreakable soft body bunny physics. You can flatten it and throw it around with your mouse.

## 11. Find overlaps among objects

Find overlaps among thousands of objects blazing fast. Implements a version of the Spatial Partitioning design pattern called "Spatial Hashing" which is really useful if you have an unbounded grid.

## 12. Optimized soft body physics (TODO)

Is not optimizing the code from #11, but is showing how you can use a more detailed mesh and make that faster. You use two meshes: one with fewer triangles that is tetrahedralized, and one with more triangles, and then they interract during the simulation.

## 13. Tetrahedralizer (TODO)

Implemetation of an algorithm that splits a mesh into tetrahedrons. Will be available here when finished: Open source Computational Geometry library

## 14. Cloth simulation

Basic cloth simulation.

## 17. Eulerian Fluid Simulator with 200 lines of code

Spoiler: It's just the simulation part that's 200 lines of code. You need a few more lines of code to set it up, display it on screen, etc. Watch this YouTube video for examples:

## 20. Height-field water simulation

Simulate a swimming pool with balls.

# Bonus

Bonus implementations related to the code above.

## 3-Body Problem

Simulation of planetary orbits based on this famous unsolved problem (https://en.wikipedia.org/wiki/Three-body_problem). Watch this YouTube video for examples:
