1c218bffed Add an 'extension' pointer to btCollisionObject for some of our Bullet extentions (a custom constraint solver that needs a back-pointer) 2010-04-13 21:43:34 +00:00

1f38568f14 Fixing serialization issues introduced in previous commits:
0 maps to 0 (for getUniquePointer)
use getUniquePointer for names too

9acb3d1805 Added some improvements on Bullet serialization:
Introduced generated unique id's, instead of the pointer address to avoid 64bit->32bit truncation issues
Use serializer->getUniquePointer instead of directly using a pointer

moved  ChunkUtils::getNextBlock to bFile::getNextBlock.
Moved 'TEST_BACKWARD_FORWARD_COMPATIBILITY' to bDNA.cpp. Enable the define for further testing of .bullet format
Removed duplicate definitions and use the one in LinearMath/btSerialization.h

40dc18f604 remove Extras/obsolete/quickstep
improve serialization based on feedback: make it easier to serialize a single object, or single shape, or single bvh.
Modified Bullet/Demos/ConcaveDemo to use btSerializer to serialize the btOptimizedBvh (or optionally the trimesh+bvh)

You can also serialize trimesh without BVH, use:
serializer->setSerializationFlags(BT_SERIALIZE_NO_BVH);//	or BT_SERIALIZE_NO_TRIANGLEINFOMAP

3da9c832ae Initialize the world transform to identity for btCollisionObject/btRigidBody.
Some developers only initialize the world position, and not the orientation -> uninitialized data. 

We should probably add some warning in btTransform, in debug mode. Note we don't initialize btTransform/btQuaternion/btVector3/btMatrix3x3 default constructor, for performance reasons.

badf723257 Replace all hardcoded 1e30(f) by BT_LARGE_FLOAT, defined in btScalar.h as 1e18(f) so that its square still fits in FLT_MAX
Thanks to Ole K. for reporting! http://code.google.com/p/bullet/issues/detail?id=206

459c22e7cb Synchronized changes of Bullet, from Blender.
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)

1c0fa00bc7 + provide access to 'root' collision shape, in case the original collision shape is temporarily replaced by a child collision shape.
+ added MultiMaterialDemo showing how to use the new btTriangleIndexVertexMaterialArray.
Thanks to Alex Silverman for this contribution!

1139c06a4d more soft body preparations, moved some parts from Demo/SoftBody to src/BulletDynamics/SoftBody
moved Extras/ConvexHull/btConvexHull.* to src/LinearMath/btConvexHull.*
removed btCollisionObject::m_internalOwner, replaced it by m_internalType. This should not affect external API (it was clearly marked as internal)

e252f5cadd Bugfix: allow btCollisionObjects (non-btRigidBody) to interact properly with btRigidBody for cache-friendly btSequentialImpulseConstraintSolver.
Thanks Andy O'Neil for pointing this out.

ea3dfb4ca3 made 'calculateLocalInertia' const, thanks to cgripeos, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1514
- applied a large patch to remove warnings
Thanks to Enrico, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1568
- removed SSE includes, added #incude <string.h> for memset in Extras/quickstep, thanks Eternl Knight
- disabled 16-byte alignement on btQuadWord class, it causes problems under PS3 Linux. Need to check out why.

bf967a458a applied patches from Marten (Starbreeze) for per-rigidbody sleeping thresholds, access to constraint references.
Also added assert, to make sure users don't delete rigidbodies while constraints point to them.

ced94d63bf Thanks to Mårten Svanfeldt for the contribution:

- improved debug rendering with support for compounds, spheres, capsules

0757f1fe9e add 'force activate', for static/kinematic objects that get moved.
fixed some activation issues with kinematic objects

07873854a4 more small refactoring: some methods were still upper-case. 2006-11-03 04:32:48 +00:00

b14ccdaa57 rename treshold into thresold (spelling mistake)
added cr/linefeed at end of btDefaultMotionState.h

3a6942fb91 processed a lot of feedback: added 'realtime' simulation with fixed substeps (and clamping maximum number of substeps), this means that when stepSimulation is called with smaller timesteps then 'fixed substep' the motionstate is interpolated.
renamed m_ccdSweptSphereRadius,
enabled wireframe debugDrawObject (using debugDrawer)

bf847b839a another large series of changes, related to the refactoring.
CompoundShapes are tricky to manage with respect to persistent contact points and swapped order of btCollisionObjects,
During dispatch, finding an algorith etc. order can be swapped.
fixed several other issues, related to SimpleBroadphase (removing a proxy was not working)

2aaab1ab1a Assorted cleanup of compilation warnings. Also fixed some actual errors:
#include "renderTexture.h"...when the file is actually called 'RenderTexture.h'.

d38549aa54 more refactoring, removed PhysicsInterface, cleaned up demos to make use of btDynamicsWorld derived classes.
removed two cached optimizations, type in btTransform and cached inverse transform (todo: test performance impact)
committed fixes that make the code adhere to 'who creates it, also destroys it'

eb23bb5c0c merged most of the changes from the branch into trunk, except for COLLADA, libxml and glut glitches.
Still need to verify to make sure no unwanted renaming is introduced.

37a53ee7d9 small cleanup in the DemoApplication, removed references to obsolete PHY_ShapeProps/PHY_MaterialProps
removed deletion of motionstate in CcdPhysics/CcdPhysicsController destructor
disabled m_type optimization in SimdTransform (making the memory size 64 byte, potentially more cache friendly)
fixed a bug in island generation, causing the activation not propagating in one frame, but one 'layer' of rigidbodies at a time

0e04cfc806 First stage in refactoring Bullet: moved Bullet Collision and Dynamics and LinearMath into src folder, and all files in Collision Detection and Dynamics have bt prefix.
Made all buildsystems to work again (jam, msvc, cmake)
