2a856f8c32 add support for clipFaceAgainstHull, so we can clip convex polyhedra against triangles (without connectivity information)
in addition to the existing clipHullAgainstHull
Fix for debug drawing of contact points
comment-out some debug drawing code for triangle meshes

77b773f470 more improvements, copy testFile.bullet to target binary directory (cmake), fix some warnings 2010-01-30 21:46:50 +00:00

7b41af1765 Don't use GLUT by default under Windows, but a Win32 App instead. All demos have to be fixed (only basic demo works now). Also on Mac OSX, we plan to use cocoa instead of Glut. 2010-01-19 22:59:49 +00:00

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

33029ad996 updated demos -> ALT + mouse uses Maya-style controls, replaced BMF_Fonts by GLDebugFont
fix debug drawing of btMultiSphereShape
added box2d demo
added experimental gpu 2d demo

a8ec916af0 Added Height Field Fluid Demo to Bullet. All code stored in the Demos/HeightFieldFluidDemo directory for now.
Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes.

The implementation is still lacking in my ways:
1) Need to complete more collision algorithms for buoyant collision shapes
2) Support compound buoyant shapes
3) The buoyancy model isn't that great
4) Fluid volume can be lost over time

6f28170422 Removed obsolete btPoint3: use btVector3 instead 2008-10-27 19:56:48 +00:00

4cbb3f2e7b Added btGhostObject and btPairCachingGhostObject functionality.
It is a fast way to keep track of overlapping objects in an area, and doing rayTest and convexSweepTest for overlapping objects, instead of btCollisionWorld::rayTest/convexSweepTest.

Updated KinematicCharacterController to use btPairCachingGhostObject.

f8e5481612 Added method to collect all persistent contact manifolds, given a btBroadphasePair (collision algorithm)
virtual	void	getAllContactManifolds(btManifoldArray&	manifoldArray)
See Demos/CharacterDemo/CharacterDemo.cpp for example usage of getAllContactManifolds
Added btDbvtBroadphase to btBulletCollisionCommon.h headerfile
Enable soft body vs concave (albeit slow)
Improved contact point debug rendering (moved from constraint solver into debugDrawWorld)

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

d4698cb3d5 Added SoftBody demo, contribution by Nathanael Presson. Will integrate into Bullet broadphase.
Added very basic drawTriangle for btIDebugDraw, useful for basic softbody visualization.
Added btGjkEpa2, contribution by Nathanael Presson. Improved version of EPA penetration depth computation, more suitable for multi-core/SPU (less memory usage). Note: btGjkEpa2 is not enabled by default currently.

e7caaa28d3 re-organized memory (stack and pool) allocators. this lets the user pass in their own memory allocators. 2007-10-20 02:23:39 +00:00

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

054d672592 - removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal).
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015

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

50a2694c5b more compounds work, the basics work. now some stackless tree-tree traversal is needed to speedup compound versus compound. 2006-07-24 23:06:59 +00:00
