642a6821a5 remove speculative contacts, they break restitution and cause other artifacts
use btConvexPolyhedron for debug rendering, if available
fixes in btConvexConvexAlgorithm for polyhedral contact clipping, if GJK separating normal is zero
don't shift vertices in btPolyhedralConvexShape

563654fb6e Add soft body anchor 'm_influence' to control the solver.
Thanks to Gregory Jaegy, see Issue 502
Avoid using btTransform to update btSoftBody (bounds are already in worldspace)
Use btConvexHullComputer for soft body cluster debug rendering
Fix soft body demo issue of invisible soft bodies (rendering was not enabled properly)

844a54a409 Fix broken CDTestFramework
Avoid crash in BulletWorldImporter, ignoring 'invalid' constraints between two static bodies
Use a bitfield for btCollisionObject::CollisionObjectTypes (to allow custom types that are derived from build-in types such as btRigidBody)
Revert/improve softbody debug rendering

d7a07e9745 Make 'randomizeConstraints' optional, switched on by default (to keep existing behaviour)
Thanks Benoit for the report: http://code.google.com/p/bullet/issues/detail?id=315

2ef7c1a457 Fixes / improvements in soft body:
avoid blow-up due to improper mass calculation for fixed nodes (happened when using clusters)
allow to create collision clusters for each tetrahedron or triangle, when using btSoftBody::generateClusters(0)
tweak soft body demos a bit, only draw debug wireframe if necessary

f492899499 Added example of tetrahedral (volumetric) softbodies
Keep camera distance positive when using mouse zoom
Updated autogenerated msvc projectfiles
Added glut 64 bit support

40c73f327c + CMake build system fix under Windows: don't define _WINDOWS to allow Glut console demo to build properly
+ 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

5feea39803 Fix compilation for MSVC 6.0 for Bullet and COLLADA DOM.
Fix issues with btDbvt: use ATTRIBUTE_ALIGNED16
Removed several places where variable was declared within for statement: for (int i=0; should be int i; for (i=0

07b577fd86 make debugDrawWorld virtual for btSoftRigidDynamicsWorld
Move btSoftBodyWorldInfo to public, instead of nested, so it can be easier forward declared.
See http://code.google.com/p/bullet/issues/detail?id=78

Add get methods for damping/thresholds, see http://code.google.com/p/bullet/issues/detail?id=77

d71f8d6623 Added several updates for btSoftBody: convex cluster collision detection, new constraints, new demos (only enabled in SoftBodyDemo, todo for AllBulletDemos) etc.
Thanks a lot to Nathanael Presson for this update.

884a494412 make the source code compile with older compilers again (Visual Studio 2006 in particular)
renamed btDbvt::Volume to btDbvtVolume and btDbvt::Node to btDbvtNode to distinguish from btSoftBody::Node

bd97c5e569 Fixed warnings in Bullet/src core library
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

6989ea8908 upgrade version to 2.69
moved btDbvt/btDbvtBroadphase to BulletCollision/BroadphaseCollision
applied code-layout to btSoftBodyHelpers.*

25c5d0d57a +Added btDbvtBroadphase, this very fast/efficient broadphase is based on Dynamic AABB tree (btDbvt).
+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

be2490e4fb Final 2.68 from Nathanael Presson, mainly soft body related. Added raycast support for soft bodies (press comma-key in the soft body demos to toggle ray cast tests) 2008-04-14 06:24:56 +00:00
