Stack Summary

This package contains version 2.76 of the Bullet professional free 3D Game Multiphysics Library. The ROS package automatically downloads, extracts and compiles a tarball. For each major release of the Bullet library, the tarball will get updated. The Bullet library provided by this ROS package is slightly different from the official Bullet release.

  • To eliminate ambiguity about which API is active the btQuaternion constructor from Euler angles is deprecated. Please explicitly construct it and populate it seperately from euler angles, otherwise it is ambiguous as to what convention is being used.
  • The btMatrix3x3 and btQuaternion setEulerZYX and getEulerZYX methods are deprecated. The goal of these deprecations is to remove the existing patch against Bullet which makes them consistent. They will be deprecated for a few releases, then patched out for a few releases before being reintroduced in their native form. setEulerYPR and getEulerYPR are drop in replacements. Also available is getRPY setRPY which use fixed axis notation about XYZ axes.
  • There are a few errors in documentation and btMatrix3x3::getEulerYPR has been changed to be a pass through to getEulerZYX for it is a better implementation of the same method. These are filed under issue 282.
  • For standardization and continuity Fixed Axis getRPY and setRPY methods have been added to btQuaternion and btMatrix3x3. These will be pushed back to Bullet, and hopefully accepted. These are the same format as used by kdl and gazebo. Standardization survey and decision at on the ROS wiki. These patches have been pushed back in issue 285 This patch will be maintained in parallel if Bullet does not accept it.
  • There is a patch against the btQuaternion angle and getAngle methods to clamp floating point errors to prevent nan results. See issue 98.
  • We have the intention to move towards the official version of Bullet; this however will take some time because it involves a number of deprecation cycles for the conflicting quaternion constructor.
  • This usage of bullet compiles with the flags -DBT_USE_DOUBLE_PRECISION -DBT_EULER_DEFAULT_ZYX set.
