+ use real-time for soft body demo (using this pre-tick callback)
+ optimize the generation of bending constraints for the special case where the distance is 2
+ Allow user to enable useConvexConservativeDistanceUtil . Use dynamicsWorld->getDispatchInfo().m_useConvexConservativeDistanceUtil = true;
(see Demos/Benchmarks/Benchmark4 (convex objects falling down)
+ Fix for plane drawing (just wire-frame)
+ Gimpact: use collision margin of 0.07 for demo (because BULLET_TRIANGLE_COLLISION is used)
+ replace dot,cross,distance,angle,triple in btVector3 by btDot, btCross,btDistance,btAngle,btDistance to avoid naming conflicts
+ Some fixes in GJK penetration depth normal direction (broken in a previous commit)
+ fix in calculateDiffAxisAngleQuaternion to make ConvexConservativeDistanceUtil work properly
+ allow debug drawing to debug btContinuousConvexCollision
+ add comment/warning that btTriangleMesh::findOrAddVertex is an internal method, users should use addTriangle instead
Added optional flag btSoftBody::appendAnchor( int node,btRigidBody* body, bool disableCollisionBetweenLinkedBodies=false), to disable collision between soft body and rigid body, when pinned
Added btCollisionObject::setAnisotropicFriction, to scale friction in x,y,z direction.
Added btCollisionObject::setContactProcessingThreshold(float threshold), to avoid collision resolution of contact above a certain distance.
Avoid collisions between static objects (causes the CharacterDemo to assert, when a dynamic object hits character)
currently self-collision is always enabled for soft bodies that use clusters collision detectoin. to disable, call 'softbody.m_clusterConnectivity.clear' after 'generateClusters(...) call.
btQuantizedBvh has a version number, memory layout might be different now (due to aligned btVector3)
reorganized some data members of some classes, to reduce memory footprint
Renamed collideRay -> rayTest to reflect change to (rayFrom,rayTo) interface.
Re-use btRayAabb2 function from src/LinearMath/btAabbUtil2.h in btDbvt instead of duplicated implementation.
added vertex welding option for btTriangleMesh (brute-force slow)
reject appendFace for some degenerate triangles (all 3 vertices/nodes need to be different)
add setVelocity method for btSoftBody
btDbvtBroadphase:
- Fixed a performance issues reported by 'reltham'
- Added btDbvtBroadphase::optimize() for people who want good performances right away or don't do dynamics.
- fixed compilation issues when DBVT_BP_PROFILE was set.
btSoftBody:
- Fixed singular matrix issues related to polar decomposition (flat meshes).
DemoApplication:
- Shadows (enable/disable through 'g' or DemoApplication::setShadows(bool)).
- Texture can be enable/disable through 'u'
CDFramework:
- fixed compilation issues.
Thanks Martijn Reuvers from Two Tribes B.V. (www.twotribes.com) for the patch
To make this work more visible, suppress warnings in external libraries in Extras (COLLADA_DOM, libxml and glui contain many warnings)
Added PreprocessorDefinitions: _CRT_SECURE_NO_DEPRECATE;_CRT_NONSTDC_NO_DEPRECATE to vcproj files
+SoftBody improvements by Nathanael Presson:
+Add tetrahedralization
+Add support for tearing/slicing cloth and deformable volumes. Uncomment the line in Bullet/src/BulletSoftBody/btSoftBodyHelpers.h: //#define BT_SOFTBODY_USE_STL 1
