  • Bugfix: JVM crash while serializing BoundingValueHierarchy (issue #41)

  • Bugfix: crash in processAllTriangles() when m_bvh==NULL (issue #43)

  • Bugfix: wrong inertia for a CustomConvexShape when mass != 1

  • Changed the default setting for collision-shape contact filtering (from enabled to disabled) to address issue #40. This change may cause unwanted behavior for rigid bodies in contact with a gimpact, heightfield, or mesh shape; see issue #18 for details.

  • Started regenerating the bounding-value hierarchy if it was serialized with a different floating-point precision.

  • Bugfix: the RK4 flag of a MultiBody isn't de-serialized

  • Added 2 convex collision shapes:

    • ConicalFrustum
    • SphericalSegment

  • Made BVH serialization optional:

    • MeshCollisionShape.isSerializingBvh()
    • MeshCollisionShape.setSerializingBvh()

  • Added a setting to visualize the collision margins of concave shapes.

  • Added the new CollisionConfiguration class and related methods, to configure penetration depth solvers:

    • BulletAppState.getCollisionConfiguration()
    • BulletAppState.setCollisionConfiguration()
    • CollisionSpace.getConfiguration()
    • PhysicsDescriber.describe(CollisionConfiguration)
    • a 5-argument CollisionSpace constructor
    • a 4-argument PhysicsSoftSpace constructor
    • a pair of 5-argument PhysicsSpace constructors

  • Added 14 accessors for the native user indices of CollisionShape, MultiBody, and PhysicsCollisionObject.

  • Added 20 other public methods:

    • BoundingValueHierarchy.copyAabb()
    • BoundingValueHierarchy.copyQuantization()
    • BoundingValueHierarchy.countLeafNodes()
    • BoundingValueHierarchy.countNodes()
    • BoundingValueHierarchy.countSubtreeHeaders()
    • BoundingValueHierarchy.escapeIndex()
    • BoundingValueHierarchy.isCompressed()
    • BoundingValueHierarchy.isLeafNode()
    • BoundingValueHierarchy.partId()
    • BoundingValueHierarchy.setTraversalMode()
    • BoundingValueHierarchy.traversalMode()
    • BoundingValueHierarchy.triangleIndex()
    • GImpactCollisionShape.countSubmeshes()
    • GImpactCollisionShape.getSubmesh()
    • HeightfieldCollisionShape.countColumns()
    • HeightfieldCollisionShape.countRows()
    • HeightfieldCollisionShape.upAxis()
    • MeshCollisionShape.countSubmeshes()
    • MeshCollisionShape.getBvh()
    • MeshCollisionShape.getSubmesh()

  • Enhancements to the MinieExamples subproject:

    • Added 2 test apps:
      • TestIssue40
      • TestIssue41
    • Added 3 custom collision shapes:
      • CustomLemon
      • CustomParaboloid
      • CustomSegment
    • Added more options to the ShapeGenerator class and also to the DropTest and SplitDemo apps.
    • Started displaying the number of persistent manifolds in the DropTest app.
    • Reduced the CCD motion threshold in the DropTest app.
    • Added getters for the dimensions of custom collision shapes.
    • Made 4 custom collision shapes more scalable.
    • Added margin to the radii of custom collision shapes.

  • Updated dependencies: v3.0.1 of the jme-ttf library and v20.13.0 of Node.js .

  • Built using Gradle v8.7 .

  • Updated the native libraries to v21.2.1 of Libbulletjme.

  • Updated VHACD v4 to version 4.1 .
