Javascript Physics Library Tests

A small application used to test, compare and benchmark various physics libraries for Javascript.

So far there are three different demos for each library; I've tried to keep the demos as similar as possible across engines to allow them to be easily compared.

Demos

• Basic - Randomly creates simple bodies.
• Constraints - Compares similar constraints available in each engine.
• Ragdoll - How well does each engine handle rag dolls?
• Stress - Creates a large number of bodies - a good way to measure the performance of each engine.

A lot of these tests have been adapted from the Nape and Box2DFlash websites.

Libraries

• Nape - http://napephys.com/
  • Complete with lots of features
  • Possibly the best performance and accuracy in stress test
  • Very large file size
  • Ported from AS3/Haxe
  • Lacks an organised Javascript port
  • Updated within the last year or two (as of Nov 2016)
• Box2DWeb - https://github.com/hecht-software/box2dweb
  • Complete
  • Good performance on the stress test - similar to Nape
  • Ported from C++/AS3
  • Last updated one or two years ago (as of Nov 2016)
• p2.js - http://schteppe.github.io/p2.js/
  • Complete
  • Poor performance on the stress test
  • Updated within the last few months (as of Nov 2016)
• Matter.js - http://brm.io/matter-js/
  • Incomplete - lacks support for many constraints
  • Poor performance on the stress test
  • Updated recently (as of Nov 2016)
• PhysicsJs http://wellcaffeinated.net/PhysicsJS/
  • Incomplete - lacks support for many constraints
  • Cannot handle the stress test
  • Seems like it was last updated 2 years ago (as of Nov 2016)
