Allow btBulletWorldImporter to convert/export a .bullet file to XML Add first version of btBulletXmlWorldImporter, still incomplete but it can read some files Fix false assert in btSequentialImpulseConstraintSolver
add serialization for btGearConstraint support 'linearFactor' and 'angularFactor' for btRigidBody world importer
refactor constraint serialization, so that double precision is maintained, changes are backwards compatible (btBulletWorldImporter can load old .bullet files) but not forwards compatible (constraints in new .bullet files are ignored/unrecognized by old Bullet SDK) This commit is for Issue 734. Some more work needs to be done for btGImpactMeshShapeDoubleData and thus btStridingMeshInterfaceDoubleData and btMeshPartDoubleData
Generate a single bullet.h headerfile for serialization, to make it easier to load .bullet files with no dependencies on the Bullet SDK (except Bullet/LinearMath and Bullet/Extras/Serialize/BulletFileLoader) Added a work-in-progress example how to load a .bullet file using this bullet.h file (and not using the Bullet SDK)
