Improved version of pyphy-engine, used in "Learning Visual Predictive Models of Physics for Playing Billiards, ICLR 2016" (arXiv) to simulate the billiards environments.

Usage

1. output with default parameters (log for position and velocity)

python main.py --outDir result/

2. output frames

python main.py --outDir result/ --outIm True

3. change dynamics: friction and collision damp

python main.py --outDir result/ --outIm True --aFric 10 --aDamp 0.5

4. change setup: ball (num, size, mass, init state), table (shape)

python main.py --outDir result/ --outIm True --ballNum 2 --ballRadius 10 --ballMass 15 --ballInit 5 --tableType 0 

Improvement

• fixed bugs for multiple balls
• add friction parameter
• add collision damping parameter
