btConeTwistConstraint.cpp

Avoid a potential division by zero.

11 лет назад

btConeTwistConstraint.h

use the old data structures for single precision serialization, to make it backwards compatible So files created by the new double precision serialization of Bullet 2.82 cannot be read by old Bullet versions, but double precision serialized file generated by older Bullet versions can be read by Bullet 2.82 or newer.

btConstraintSolver.h

added the btNNCGConstraintSolver, based on the paper "Nonsmooth Nonlinear Conjugate Gradient Method for interactive contact force problems". The solver needs a lot of iterations, before the quality goes up (~ 1000) Thanks to Gabor PUHR for the contribution! Improved the btLemkeSolver. Remove the sparse optimizations from the btMatrixX.h, replace it with explicit call to rowComputeNonZeroElements (only used in the btSolveProjectedGaussSeidel), it was likely slowing things down, without being useful. Re-enable SIMD in the solver (was accidently disabled in Bullet 2.82 release)

btContactSolverInfo.h

Added experimental implicit gyroscopic force implementation, one by Michael Ewert, and another by Cooper (from OpenDE) Will also add Erin Catto's local implicit version from the GDC 2015 tutorial Added demo for btGeneric6DofSpring2Constraint, thanks to Gabor Puhr Add gfxBridge.autogenerateGraphicsObjects method for Bullet 2 demos in new framework (need to implement all Bullet 2 collision shape types...) Use 1,1,1 for local scaling in btStaticPlaneShape

btGeneric6DofConstraint.cpp

Usually m_contactNormal2 == -m_contactNormal1, but not always, so use a separate contactNormal1/contactNormal2 for each body in btSolverConstraint.

btHingeConstraint.h

add support to btHingeConstraint to set/get ERP, example use: hinge->setParam(BT_CONSTRAINT_ERP,0.5); btScalar erp = hinge->getParam(BT_CONSTRAINT_ERP); Also, preliminary support for status bar messages in demo framework.

btJacobianEntry.h

improve handling of restitution by using the velocity (linear/angular) before applying forces: this is done by re-introducing the btSolverBody and only apply the forces to solver body, and use the original rigid body velocity for restitution computation. warmstarting for contact points was broken, fix in btPersistentManifold enable split impulse by default (at the cost of some performance) add the option for zero-length friction (instead of recomputing friction directions using btPlaneSpace), use the solver mode flag SOLVER_ALLOW_ZERO_LENGTH_FRICTION_DIRECTIONS precompute lateral friction directions (in btManifoldResult) remove the mConstraintRow[3] from btManifoldPoint, it just took a lot of memory with no benefits: fixed it in btParallelConstraintSolver

btSolve2LinearConstraint.h

add the BT_ prefix for all #ifdef guards, to avoid conflicts with developers own header defines. Fixes Issue 497

Attempt to fix "Regression in friction and damping behaviour" , see issue 752 Thanks to Sergej Reich for the report and narrowing down the breaking revision!

btSolverConstraint.h

Build full A matrix and b vector for a MLCP solver interface, to explore Lemke, Dantzig, Newton and other MLCP solvers. The A matrix contains sparsity information. Added a PGS solver that uses the sparsity of the A matrix, just for testing (the equivalent sequential impulse solver is much faster, not having to allocate the big matrices)
