  • For Linear limits, use b3Generic6DofConstraint.setLinearUpperLimit, b3Generic6DofConstraint.setLinearLowerLimit.

    • + +
  • For Angular limits, use the b3RotationalLimitMotor structure for configuring the limit. +This is accessible through b3Generic6DofConstraint.getLimitMotor method, +This brings support for limit parameters and motors.

The Library is Open Source and free for commercial use, under the ZLib license ( http://opensource.org/licenses/zlib-license.php ). + * + * The main documentation is Bullet_User_Manual.pdf, included in the source code distribution. + * There is the Physics Forum for feedback and general Collision Detection and Physics discussions. + * Please visit http://www.bulletphysics.org + * + * @section install_sec Installation + * + * @subsection step1 Step 1: Download + * You can download the Bullet Physics Library from the Google Code repository: http://code.google.com/p/bullet/downloads/list + * + * @subsection step2 Step 2: Building + * Bullet has multiple build systems, including premake, cmake and autotools. Premake and cmake support all platforms. + * Premake is included in the Bullet/build folder for Windows, Mac OSX and Linux. + * Under Windows you can click on Bullet/build/vs2010.bat to create Microsoft Visual Studio projects. + * On Mac OSX and Linux you can open a terminal and generate Makefile, codeblocks or Xcode4 projects: + * cd Bullet/build + * ./premake4_osx gmake or ./premake4_linux gmake or ./premake4_linux64 gmake or (for Mac) ./premake4_osx xcode4 + * cd Bullet/build/gmake + * make + * + * An alternative to premake is cmake. You can download cmake from http://www.cmake.org + * cmake can autogenerate projectfiles for Microsoft Visual Studio, Apple Xcode, KDevelop and Unix Makefiles. + * The easiest is to run the CMake cmake-gui graphical user interface and choose the options and generate projectfiles. + * You can also use cmake in the command-line. Here are some examples for various platforms: + * cmake . -G "Visual Studio 9 2008" + * cmake . -G Xcode + * cmake . -G "Unix Makefiles" + * Although cmake is recommended, you can also use autotools for UNIX: ./autogen.sh ./configure to create a Makefile and then run make. + * + * @subsection step3 Step 3: Testing demos + * Try to run and experiment with BasicDemo executable as a starting point. + * Bullet can be used in several ways, as Full Rigid Body simulation, as Collision Detector Library or Low Level / Snippets like the GJK Closest Point calculation. + * The Dependencies can be seen in this documentation under Directories + * + * @subsection step4 Step 4: Integrating in your application, full Rigid Body and Soft Body simulation + * Check out BasicDemo how to create a btDynamicsWorld, btRigidBody and btCollisionShape, Stepping the simulation and synchronizing your graphics object transform. + * Check out SoftDemo how to use soft body dynamics, using btSoftRigidDynamicsWorld. + * @subsection step5 Step 5 : Integrate the Collision Detection Library (without Dynamics and other Extras) + * Bullet Collision Detection can also be used without the Dynamics/Extras. + * Check out btCollisionWorld and btCollisionObject, and the CollisionInterfaceDemo. + * @subsection step6 Step 6 : Use Snippets like the GJK Closest Point calculation. + * Bullet has been designed in a modular way keeping dependencies to a minimum.

    • For Angular limits, use the btRotationalLimitMotor structure for configuring the limit. +This is accessible through btGeneric6DofConstraint.getLimitMotor method, +This brings support for limit parameters and motors.

(Especially when a sleeping chain of RBs connected with 6dof2 is pulled) +- Stable and accurate spring with minimal energy loss that works with all of the solvers. (latter is not true for the original 6dof spring) +- Servo motor functionality +- Much more accurate bouncing. 0 really means zero bouncing (not true for the original 6odf) and there is only a minimal energy loss when the value is 1 (because of the solvers' precision) +- Rotation order for the Euler system can be set. (One axis' freedom is still limited to pi/2) + +Cons: +- It is slower than the original 6dof. There is no exact ratio, but half speed is a good estimation. (with PGS) +- At bouncing the correct velocity is calculated, but not the correct position. (it is because of the solver can correct position or velocity, but not both.) +*/ + +/// 2009 March: btGeneric6DofConstraint refactored by Roman Ponomarev +/// Added support for generic constraint solver through getInfo1/getInfo2 methods + +/* +2007-09-09 +btGeneric6DofConstraint Refactored by Francisco Le?n +email: projectileman@yahoo.com +http://gimpact.sf.net +*/ + + + +#include "btGeneric6DofSpring2Constraint.h" +#include "BulletDynamics/Dynamics/btRigidBody.h" +#include "LinearMath/btTransformUtil.h" +#include + + + +btGeneric6DofSpring2Constraint::btGeneric6DofSpring2Constraint(btRigidBody& rbA, btRigidBody& rbB, const btTransform& frameInA, const btTransform& frameInB, RotateOrder rotOrder) + : btTypedConstraint(D6_SPRING_2_CONSTRAINT_TYPE, rbA, rbB) + , m_frameInA(frameInA) + , m_frameInB(frameInB) + , m_rotateOrder(rotOrder) + , m_flags(0) +{ + calculateTransforms(); +} + + +btGeneric6DofSpring2Constraint::btGeneric6DofSpring2Constraint(btRigidBody& rbB, const btTransform& frameInB, RotateOrder rotOrder) + : btTypedConstraint(D6_SPRING_2_CONSTRAINT_TYPE, getFixedBody(), rbB) + , m_frameInB(frameInB) + , m_rotateOrder(rotOrder) + , m_flags(0) +{ + ///not providing rigidbody A means implicitly using worldspace for body A + m_frameInA = rbB.getCenterOfMassTransform() * m_frameInB; + calculateTransforms(); +} + + +btScalar btGeneric6DofSpring2Constraint::btGetMatrixElem(const btMatrix3x3& mat, int index) +{ + int i = index%3; + int j = index/3; + return mat[i][j]; +} + +// MatrixToEulerXYZ from http://www.geometrictools.com/LibFoundation/Mathematics/Wm4Matrix3.inl.html + +bool btGeneric6DofSpring2Constraint::matrixToEulerXYZ(const btMatrix3x3& mat,btVector3& xyz) +{ + // rot = cy*cz -cy*sz sy + // cz*sx*sy+cx*sz cx*cz-sx*sy*sz -cy*sx + // -cx*cz*sy+sx*sz cz*sx+cx*sy*sz cx*cy + + btScalar fi = btGetMatrixElem(mat,2); + if (fi < btScalar(1.0f)) + { + if (fi > btScalar(-1.0f)) + { + xyz[0] = btAtan2(-btGetMatrixElem(mat,5),btGetMatrixElem(mat,8)); + xyz[1] = btAsin(btGetMatrixElem(mat,2)); + xyz[2] = btAtan2(-btGetMatrixElem(mat,1),btGetMatrixElem(mat,0)); + return true; + } + else + { + // WARNING.

(Especially when a sleeping chain of RBs connected with 6dof2 is pulled) +- Stable and accurate spring with minimal energy loss that works with all of the solvers. (latter is not true for the original 6dof spring) +- Servo motor functionality +- Much more accurate bouncing. 0 really means zero bouncing (not true for the original 6odf) and there is only a minimal energy loss when the value is 1 (because of the solvers' precision) +- Rotation order for the Euler system can be set. (One axis' freedom is still limited to pi/2) + +Cons: +- It is slower than the original 6dof. There is no exact ratio, but half speed is a good estimation. +- At bouncing the correct velocity is calculated, but not the correct position. (it is because of the solver can correct position or velocity, but not both.) +*/ + +/// 2009 March: btGeneric6DofConstraint refactored by Roman Ponomarev +/// Added support for generic constraint solver through getInfo1/getInfo2 methods + +/* +2007-09-09 +btGeneric6DofConstraint Refactored by Francisco Le?n +email: projectileman@yahoo.com +http://gimpact.sf.net +*/ + + +#ifndef BT_GENERIC_6DOF_CONSTRAINT2_H +#define BT_GENERIC_6DOF_CONSTRAINT2_H + +#include "LinearMath/btVector3.h" +#include "btJacobianEntry.h" +#include "btTypedConstraint.h" + +class btRigidBody;
