0656de3057 premake4 compile/link fixes 2011-09-16 19:56:14 +00:00
erwin.coumans
bb29d15058 create premake4 solutions for the various OpenCL configurations (AMD, NVIDIA, Intel OpenCL SDKs for Windows) 
primarily to distribute project files that work.
CMake is still better supported in general (not all demos/libs have been ported)

Revert a recent change about warnings: %zu doesn't work in printf, %d does

144d24009a CcdPhysicsDemo: fixed the setCcdMotionThreshold value, it was wrong (way too small 2011-09-15 23:24:42 +00:00
erwin.coumans
654fe7872a remove btContinuousDynamicsWorld, it is obsolete and was never completed. 
If you need tunneling prevention, one option is to use the CCD motion clamping in btDiscreteDynamicsWorld. See also Bullet/Demos/CcdPhysicsDemo.
You can use an embedded sphere that prevents tunneling, using the following settings:

		body->setCcdMotionThreshold(0.5);
		body->setCcdSweptSphereRadius(0.9f);


Add a camera zoom setting for the demos, thanks to ejtttje, fixes Issue 543

b68c64f2db Disable DX11 cloth bounds update, it is too slow by default. 
Use g_dx11Solver->setEnableUpdateBounds(true); to re-enable it (it enables GPU collision of cloth versus capsule)

fixes in SAT/polyhedral contact clipping, avoid adding GJK contacts (the contact margin causes different contact depths)

b16b61d9d6 disable constraints when they exceed a breaking threshold, control it with new methods in btTypedConstraint: get/setBreakingImpulseThreshold and get/setEnabled 
Disabled constraints are not removed from the world and they use negligible CPU cycles

a522cb98d9 Added a first version of FractureDemo, showing basic fracture and glue of rigid bodies. 
It assumes a btCompoundShaps (where the childshapes are the pre-fractured pieces)
The btFractureBody is a class derived from btRigidBody, dealing with the collision impacts and connectivity/propagating the fracture.
Press the F key to toggle between fracture and glue mode
This is preliminary work, can be used as a starting point to implement your own fracture.
