Position Based Dynamics

Implementation

Implementation of constraint-based verlet solvers explained by Jakobsen's Advanced Character Physics and Muller's Position Based Dynamics.

You can play with the Jakobsen-style demo, the source code is under /jakobsen folder in this repository. These are the things you can do:

  • UP ARROW Increases the gravity (adds positive values).
  • DOWN ARROW Decreases the gravity (subtracts positive values).
  • Left Mouse Click & Drag Create pin constraints that drag the points.
  • Middle Mouse Click & Drag Same as left mouse but the contraints cannot break.
  • N Sets the number of iterations to evaluate the constraints.
  • B Sets the breaking threshold (in pixels) to tell when the spring constraint should break.

Some documentation about how ParticleSystem, PinConstraint and SpringConstraint.
