af5883c6e8 remove a lot of warnings (more todo in demos and serialization code) 2014-08-22 10:29:05 -07:00

8c56528a79 Avoid using restitution for ccd motion clamping. Restitution for fast moving objects should be handled by btDiscreteDynamicsWorld::createPredictiveContacts 
(make sure to merge islands based on those predictive contacts too, added some check in the solver)
This fixes Issue 356.
Use same solver settings for AllBulletDemos
Make sure to embed the setCcdSweptSphereRadius inside the actual collision shape (for shoot box)

cdddf9d25a add FractureDemo to AllBulletDemos 
improvements in CCD handling
some cleanup of CcdPhysicsDemo and BasicDemo

d4c3633405 Get rid of btSolverBody and use btRigidBody directly. btSolverBody didn't improve performance after all, due to random-access 
Tweak the BenchmarkDemo a bit: 

1) disable deactivation in graphical mode
2) add some settings that increase performance in the BenchmarkDemo2 (1000 stack) from 35ms to 15ms on this quad core (at the cost of a bit of quality)

1cd52f3d11 Removed empty constructors for constraints, I don't recall why we added them (possibly SPU) but if we really need them we have to revert this. 
Moved static fixed body into a static function 'getFixedBody' to avoid issues when embedding Bullet in C#/CLI managed code.

3e2529fcb5 Minor constraint refactoring, to allow SPU-side processing for PLAYSTATION 3 (added non-virtual methods) 
Also comment-out some code for __SPU__ to reduce code size
Added btContactConstraint (only used on PS3 SPU right now, better to use btPersistentManifold directly for contact constraints)
Improved readblend utility library (see also usage in http://gamekit.googlecode.com with Irrlicht)

Fix for btConvexConvexAlgorithm, potential division by zero
Thanks linzner http://code.google.com/p/bullet/issues/detail?id=260

7a2a98078a Fixes for broadphase/paircache determinism. 
Revert definition for ATTRIBUTE_ALIGNED16, and try to force sizeof(btSolverConstraint) by using unions with btScalar, for non-btScalar data types.
Use btAssert and not assert.
Don't access btAlignedObjectArray elements, for zero sets

5383ed4930 + need to reset rigid body using 'setCenterOfMassTransform' to reset world inertia tensor 
+ fixes in compound algorithm -> recompute contact points
+ add debug drawing to some demos.
+ revert btJacobianEntry change
+ replace dCROSSMAT by btVector3::getSkewSymmetricMatrix

82047e601e updated Bullet sequential impulse constraint solver, so it matches 100% ODE PGS quickstep solver innerloop, mainly by renaming variables... 2008-11-26 00:27:35 +00:00

003b6fa669 removed some warnings, as reported here:

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

bc3f9535ad cleaned up, removed warning under MSVC2005 (Level 4) 
Mostly related to alignment and unused variables

4050da0e2f One of the last parts of the refactoring (hopefully), made most members of btCollisionObject protected. 
Also did some work on improving the constraint solver.

3fe3b11924 use Dispatcher in ConcaveConvexCollisionAlgorithm (so it uses the registered collision algorithm, not hardcoded convexconcave) 
improved performance of constraint solver by precalculating the cross product/impulse arm
added collision comparison code: ODE box-box, also sphere-triangle
added safety check into GJK, and an assert for AABB's that are very large
write partid/triangle index outside of GJK

2b1657b1dd Refactoring: another huge number of changes, renamed methods to start with lower-case. 2006-09-28 01:11:16 +00:00

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.

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)
