22fb7d5c1e improve rolling friction using anisotropic direction, to avoid resting in an instable position 
(for implicit capsule, cylinder and cone shape)
See Bullet/Demos/RollingFrictionDemo for an example

7eebb79ced implemented rolling friction, using a contact constraint. Useful to get rolling spheres to rest, even on a slightly sloped plane. 
See http://www.youtube.com/watch?v=RV7sBAsKu4M and Bullet/Demos/RollingFrictionDemo
Fixes in FractureDemo (mouse picking constraint needs to be removed, otherwise constraint solver crashes/asserts)

54744b6ab9 added gyroscopic force option for btRigidBody, body->setFlags(BT_ENABLE_GYROPSCOPIC_FORCE); 
Note that it can easily introduce instability at regular (60Hertz) simulation steps so it is generally best to not use the option.
If needed, use a very small internal step, such as 1000 Hertz (world->stepSimulation(dt,100,1./1000.f); or stepSimulation(1./1000.,0);

8c56528a79 Avoid using restitution for ccd motion clamping. Restitution for fast moving objects should be handled by btDiscreteDynamicsWorld::createPredictiveContacts 
(make sure to merge islands based on those predictive contacts too, added some check in the solver)
This fixes Issue 356.
Use same solver settings for AllBulletDemos
Make sure to embed the setCcdSweptSphereRadius inside the actual collision shape (for shoot box)
 2012-09-11 03:12:32 +00:00
erwin.coumans
9612561113 add btDiscreteDynamicsWorld::createPredictiveContacts after discrete collision detection and add temporary contact manifolds, for the constraint solver. 
This should improve 'ccd' handling when using world->getDispatchInfo().m_useContinuous = true;body->setCcdSquareMotionThreshold(...); body->setCcdSquareMotionThreshold(...)
shoot smaller boxes (test)
use yellow instead of orange for contact point normals
tweak default erp and erp2 values, now split impulse is on by default (need to check it)

196aa20329 add m_splitImpulseTurnErp solver setting, initialized to 0.1: more stable recovery from deeper penetrations by reducing the angular effect (if split impulse is enabled) 
Set it to 1.0 to disable the effect.

73b217fb07 Apple contribution for OSX SSE and iOS NEON optimizations unit tests, thanks to Jordan Hubbard, Ian Ollmann and Hristo Hristov. 
For OSX:
cd build
./premake_osx xcode4
for iOS:
cd build
./ios_build.sh
./ios_run.sh

Also integrated the branches/StackAllocation to make it easier to multi-thread collision detection in the near future. It avoids changing the btCollisionObject while performing collision detection.

As this is a large patch, some stuff might be temporarily broken, I'll keep an eye out on issues.

fix in infinite recursion in quickSort, exclude the pivot in each sub partition
disabled constraints don't merge simulation islands, and they don't disable collision between linked rigid bodies either.

0daf69afb6 Add an improved way to approximate the area of the contact manifold, using 4 points instead of 3. It is switched off by default (need to check performance first), use gContactCalcArea3Points = false to enable it. Thanks to Hiroshi Matsuike for the improvement!
