7ae29bd13e add plSetOpenGLMatrix to Bullet-C-API 2009-03-10 00:13:18 +00:00
erwin.coumans
700db838b1 Add 1D and 2D support for Bullet: using rigidbody->angularFactor(const btVector3& factor) and body->setLinearFactor(const btVector3& linearFactor); 
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
	body->setLinearFactor(btVector3(1,0,1));
	body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
${OPENGL_glU_LIBRARY} should be ${OPENGL_glu_LIBRARY}
Fix build issue with CodeBlocks, comment out xmlfree in Extras/COLLADA_DOM/src/modules/LIBXMLPlugin/daeLIBXMLPlugin.cpp (will leak memory)

90f96aec27 Introduced btActionInterface. This makes it easier to extend user-defined actions, such as vehicles and characters. 
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.

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

0754876d77 Calculate multiple contact points (for convex-convex and convex-plane) when less then 3 points exist in the persistent manifold.

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
