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/
  1. output frames
python main.py --outDir result/ --outIm True
  1. change dynamics: friction and collision damp
python main.py --outDir result/ --outIm True --aFric 10 --aDamp 0.5
  1. 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

Additional parameters --fps and --numFrames can be used to control the frames per second in the simulation and the number of frames the simulation is run for.

Improvement

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