aafbf48130 Fix linux|mingw shared|static build 2014-04-09 10:33:22 +00:00
erwincoumans
aa76b88936 Added btSoftBodyHelpers::ReoptimizeLinkOrder(btSoftBody* softBody) method, to help improve performance for modern out-of-core CPUs. 
It is tested in Aero2 demo (13) of AppSoftBodyDemo. Note that the cloth in Areo2 is not expensive enough to see benefits. Increase segments to see benefits.
Thanks a lot for the contribution.

c782f4976c Various minor PLBVH related changes. 
-Use most significant bit instead of negative for internal nodes.
-Explicitly store root node index, so that it does not have to be 0.
-Check the root node first in PLBVH traversal.
-Fix rigid body clipping in RaytracedShadowDemo.

d485f2b272 btMultiBodyConstraintSolver writes back the applied impulse for contact points 
(added some debugging output for this in the demos, commented-out by default)

dfa738c13a Properly propagate the applied impulse for the MLCP solvers, so it will be available for contact and non-contact constraints. 
Use real-time clock in AllBullet2Demos, rather than hard-coded 1./60.
