b8d293c1fe Fixes for double precision compilation 
Thanks to Dennis Cappendijk for the report and fix
See Issue 575

3035ee69c4 Fix for btCapsuleShape, m_localScaling is already applied to the radius/halfExtents so don't apply it again in the localGetSupportVertex(NonVirtual) 
Make sure SerializeDemo compiles fine without DESERIALIZE_SOFT_BODIES defined

1b305562be Added Pierre Terdiman's 'internal object' optimization to improve performance for separating axis tests. 
Make the winding consistent in btConvexHullComputer (and related fixes in btPolyhedralConvexShape), thanks to Ole!
Some fixes in the btPolyhedralContactClipping implementation (never report a penetration deeper than GJK/EPA found, to avoid issues due to its approximate contact normal directions)
Properly visualize btPolyhedralConvexHullShape that have a  btConvexPolyhedron (by calling initializePolyhedralFeatures() method)

d67aa861f2 Add support for childshape index for btCompoundShape during ContactAddedCallback, 
see example in Bullet/Demos/ConvexDecompositionDemo
Removed some warnings

aef97d6015 Share btGjkPairDetector, btGjkEpa2, btVoronoiSimplexSolver with SPU/Multithreaded implementation (remove duplicate code) 
Make btTypedConstraint and btPersistentManifold both derive from btTypedObject to make SPU-side generic constraint solver easier.

Note: all build systems need to be updated: remove SpuVoronoiSimplexSolver.cpp, SpuGjkPairDetector.cpp, SpuEpaPenetrationDepthSolver.cpp, SpuGjkEpa2.cpp

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

2f1014268b + Internal improvements for collision shapes 
1) add AabbCaching versions of btPolyhedralConvexShape and btMultiSphereShape (this speeds up btMultiSphereShape 'getAabb', and reduces size of btBoxShape)
2) btCylinderShape doesn't derive from btBoxShape anymore
+ Minor fixes in drawing for btMultiSphereShape, btBoxShape.
+ Don't re-generate btDebugFont every frame
+ Disabled velocity prediction for btDbvtBroadphase. Previous default can be restored using btDbvtBroadphase->setVelocityPrediction(1./2.);

cef40e5cce no 'const int' but inline for a few methods 
remove redundant/unreachable 'breaks'

a4c205afc0 enable convex separation util, potentially improves performance. set threshold to zero (docs follow) 
fix scaling issue with btConvexHullShape
use virtual getSupportingVertex on non-SPU platform

0ff15db3f3 + capsule should subtract margin, and take local scaling into account. 
+ boxshape uses btFsels
+ add assert in btGjkPairDetector that the new non-virtual method produces the same result as old non-virtual

2b71784c86 Make getShapeType() a non virtual function. 
Add localGetSupportVertexNonVirtual, localGetSupportVertexWithoutMarginNonVirtual, getAabbNonVirtual and getMarginNonVirtual methods to convex shape classes

38b7f474c3 Added better support for btUniformScalingShape, by moving some data that is not shared from btConvexShape to btConvexInternalShape. This reduces the sizeof btUniformScalingShape to 16 bytes (from 64). 
This is good when having lots of re-used shapes with different sizes.

Convex shapes will need to derive from btConvexInternalShape (which is a subclass of btConvexShape). We could have renamed btConvexShape to 'btConvexShapeInterface' (can still do that later)

df9230327c Contribution to add optional double precision floating point support. Define BT_USE_DOUBLE_PRECISION for all involved libraries/apps. 2006-12-16 05:51:30 +00:00

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

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)
