Minie v0.6.3

Important changes to the library:

• Prohibited PhysicsRigidBody.setKinematic() on static bodies.
• Use EmptyShape to permit linking a bone without vertices in a DynamicAnimControl.
• Added getSpatial() methods to GhostControl and RigidBodyControl.
• Updated the native libraries to version 1.0.24 of jme3-bullet-native.

Important changes to the examples:

• Added new apps: HelloDac, HelloBoneLink, TestHullContact.
• Added apps from the jme3-examples (sub)project: TestSimplePhysics, TestRagdollCharacter, and TestBoneRagdoll.
• Added example tuning for CesiumMan model. (model not provided)
• Simplified the example tuning for the Jaime model.

Minie v0.6.2

• Fixed bug where SimpleSolidControl.onAdd() threw a NullPointerException if the control wasn't added to a PhysicsSpace.
• Added a countJoints() method to PhysicsRigidBody.
• Added a setLimit() method to HingeJoint.
• Allowed vertical translation of heightfields.
• Based on version 2.18 of the jme3-utilities-heart library and JME 3.2.2-stable.

Minie v0.6.1

• Added an option to calculate local coordinates in DynamicAnimControl.findManagerForVertex().
• Added a chainLength argument to DynamicAnimControl.setDynamicChain().
• Finalized 4 library methods.
• Created a CameraOrbitAppState class for use in examples.
• Based on version 2.17 of the jme3-utilities-heart library and JME 3.2.2-beta1.
• Disable scene-graph culling for animated models in examples.

Minie v0.6.0

Noteworthy additions:

• An IKController class for inverse kinematics. Each PhysicsLink maintains a list of IK controllers.
• 3 IK joint creation methods in DynamicAnimControl: moveToBody(), moveToWorld(), and pinToWorld().
• Each DynamicAnimControl keeps a list of IK joints and disables those joints when entering ragdoll mode.
• A BalanceDemo with 2 examples of IKController.
• An EmptyShape class.
• A setDynamicChain() method in DynamicAnimControl.
• Optional Biped and Binocular interfaces for DynamicAnimControl subclasses.
• A footprint() method to calculate the "footprint" of a PhysicsLink.
• An animateSubtree() method for DynamicAnimControl.
• A constructor for a single-ended Point2PointJoint with its constraint already satisfied.
• An isActive() method for all collision objects (not just rigid bodies).
• An isDetached() method for all physics links (not just attachments).
• A setContactResponse() method for physics characters (not just bodies).
• Simple compareTo(), equals(), and hash() methods for collision objects.

Bugs fixed:

• Single-ended point-to-point joints were created with incorrect world locations for their pivots.
• PhysicsRigidBody and PhysicsCharacter were not cloned properly.

Debugging improvements:

• Generally made dumps more compact by trimming trailing zeros.
• In dumps, indicate joints with out-of-space bodies.
• In dumps, indicate joints that lack a dynamic body.
• In dumps, indicate non-responsive rigid bodies.
• In visualizations, draw non-contact physics characters in yellow wireframe.

Other important changes:

• Added the concept of a DynamicAnimControl being "ready" for dynamic-mode only after the 1st physics timestep. This helps avert initialization bugs.
• Turned off hardware skinning in DacLinks.createSpatialData() to provide access to the true positions of mesh vertices.
• Modified the DynamicAnimControl.centerOfMass() method to also estimate the velocity vector of the center of mass.
• Links in kinematic mode now update their body's location and velocity for every frame, instead of just for each timestep.
• Eliminated the PhysicsJoint.getPivotInWorld() method. (API change)
• Renamed DacPhysicsLinks to DacLinks. (API change)
• PhysicsSpace accessors now return physics-object collections sorted by ID.

Other details:

• Updated the native libraries to version 1.0.21 of jme3-bullet-native.
• Based on version 2.16 of the jme3-utilities-heart library.

Minie v0.5.1

• Added a "contact response" option for rigid bodies.
• Added an isStatic() method to PhysicsCollisionObject.
• Prohibited scaling of SimplexCollisionShape.
• Added a MultiSphere constructor for a capsule shape with specified axis.

Noteworthy changes to debug visualization:

• Fixed a bug where physics objects and joints continued being visualized after setting a filter to exclude them.
• Update debug spatials on every change to debugMeshNormals or debugMeshResolution.
• For a CompoundCollisionShape, generate a new debug spatial on every frame.
• Visualize non-responsive rigid bodies in yellow.

Noteworthy changes to DynamicAnimControl:

• Added centerOfMass() and setAttachmentConfig() methods.
• Collect mesh-vertex coordinates in a HashSet (instead of an ArrayList) to increase the efficiency of createSpatialData().

Other details:

• Updated the native libraries to version 1.0.20 of jme3-bullet-native.
• Based on version 2.15 of the jme3-utilities-heart library.

Minie v0.5.0

Minie moved from the Jme3-utilities Project to a new GitHub repo.

Notable features added:

• Added single-ended versions of all 6 PhysicsJoint types.
• Added optional heuristics for configuring the center, shape, and mass of a PhysicsLink.
• Added 4 methods for compatibility with the jme3-bullet library.
• Cache and re-use debug meshes.
• Added an enable flag and a breaking impulse threshold to every PhysicsJoint object.
