Erwin Coumans has announced a new release of Bullet physics engine

  • SIMD and Neon optimizations for iOS and Mac OSX, thanks to a contribution from Apple.
  • Rolling Friction using a constraint, thanks to Erin Catto for the idea. See Demos/RollingFrictionDemo/RollingFrictionDemo.cpp.
  • XML serialization. See Bullet/Demos/BulletXmlImportDemo for XML import and use the -dump_xml option in Bullet/Demos/SerializeDemo to convert from binary .bullet to XML. Note that the XML import is work-in-progress.
  • Gear constraint, thanks to Dimitris Papavasiliou for the idea. See Bullet/Demos/ConstraintDemo.
  • Improved continuous collision response, feeding speculative contacts to the constraint solver. See Bullet/Demos/CcdPhysicsDemo.
  • Improved premake4 build system including support for Mac OSX, Linux and iOS.
  • Refactoring of collision detection pipeline using stack allocation instead of modifying the collision object. This will allow better future multithreading optimizations.
  • New force/torque joint feedback, see btTypedConstraint::setJointFeedback
  • New work-in-progress Bullet Quickstart manual, with full LaTeX source. See Bullet/docs/BulletQuickstart.pdf
