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)

177b6f5ce2 Added btUniformScalingShape (including support for debug rendering etc) 
This allows to re-use a convex shape, while each instance can re-scale it (with a uniform scalar factor)

0df4cedc3e added 'getConstraintSolver' and ability to 'reset' (set randseeds back to zero, and clear internal caches) 2007-07-27 23:54:22 +00:00

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.

685138d033 include paths should not be relative starting with "../ 
It leads to problems with certain compilers, when Bullet/src is located in a long pathname.
Keep include path starting with "LinearMath/, "BulletCollision/, or "BulletDynamics/

114bfad68f made some improvements based on feedback. 
- made getHeightFieldValue virtual (allows custom heightfield formats)
- don't use shorts, just full integers (no reason to limit the terrain size to 65536)

769809e3a7 disabled memcpy by default, it seems to be opening a can of worms, some platforms/compilers have it defined in <memory.h>, others in <string.h> etc 
also for placement new, include <new> rather then <memory.h>
Thanks Marten Svanfeldt for the help

65d10d7b12 Fixes in aligned object array, to call copy constructor, and not the assignment operator, operator= 
Also allows to use the array for classes with virtual methods.

c1250cd26a Planar triangle meshes with zero extends (in any direction) could cause quantization failures (division by zero). 
Added a positive value to quantization AABB (doesn't affect performance).

cf2337ed7b - Fixed a bug in btAxisSweep3 (sweep and prune) related to object removal. Only showed up when at least one btStaticPlaneShape was inserted. 
Thanks tbp for more details on reproducing case.
- Fixed issue with full 32bit integers in btAxisSweep3 (define BP_USE_FIXEDPOINT_INT_32), it used only 65536 for quantization, it should use full integer space (0xffffffff)
- Added 'getForwardVector' and getCurrentSpeedKmHour utility functions to btRaycastVehicle
- Fixed local scaling issues (btConvexTriangleMeshShape, btBvhTriangleMeshShape, removed scaling from btMatrix3x3). Thanks Volker for reporting!
- Added second filename search, so that starting BspDemo and ConvexDecompositionDemo from within Visual Studio (without setting the starting path) still works

3ad4316622 the relative path #include gives troubles in some cases. 
I need to revert all those back (after Steve Bakers changes a while back).
All includes should really be relative to the 'src' folder, or wherever the developer copies all the headerfiles.

2db8bfa3d6 Fix (needs more testing) in btRigidBody::setCenterOfMassTransform, assign m_interpolationWorldTransform = xform; instead of m_worldTransform; 
Thanks Jay for reporting
Added braking capability to btRaycastVehicle, see Bullet/Demos/VehicleDemo/VehicleDemo.cpp
Added glutKeyboardUpFunc, for vehicle demo (keep accelerating/breaking, until key released/UP). Hope this is compatible with most GLUT implementations.

9546633ade Added 'cache friendly' tree traversal format, and traversal. Array of subtrees with specified maximum size. This is useful to fit tree traversals on SPU. 2007-03-27 21:02:45 +00:00

7adc0742e3 Added demo code that show recursive traversal on tree data that doesn't have explicit left/right child pointers. 
Can also be used as starting point for tree versus tree.
