示例1: hapticsLoop
void hapticsLoop(void* a_pUserData)
{
// read the position of the haptic device
cursor->updatePose();
// compute forces between the cursor and the environment
cursor->computeForces();
// stop the simulation clock
g_clock.stop();
// read the time increment in seconds
double increment = g_clock.getCurrentTime() / 1000000.0;
// restart the simulation clock
g_clock.initialize();
g_clock.start();
// get position of cursor in global coordinates
cVector3d cursorPos = cursor->m_deviceGlobalPos;
// compute velocity of cursor;
timeCounter = timeCounter + increment;
if (timeCounter > 0.01)
{
cursorVel = (cursorPos - lastCursorPos) / timeCounter;
lastCursorPos = cursorPos;
timeCounter = 0;
}
// get position of torus in global coordinates
cVector3d objectPos = object->getGlobalPos();
// compute the velocity of the sphere at the contact point
cVector3d contactVel = cVector3d(0.0, 0.0, 0.0);
if (rotVelocity.length() > CHAI_SMALL)
{
cVector3d projection = cProjectPointOnLine(cursorPos, objectPos, rotVelocity);
cVector3d vpc = cursorPos - projection;
if (vpc.length() > CHAI_SMALL)

}
}
// get the last force applied to the cursor in global coordinates
cVector3d cursorForce = cursor->m_lastComputedGlobalForce;
// compute friction force
cVector3d friction = -40.0 * cursorForce.length() * cProjectPointOnPlane((cursorVel - contactVel), cVector3d(0.0, 0.0, 0.0), (cursorPos - objectPos));
// add friction force to cursor
cursor->m_lastComputedGlobalForce.add(friction);
// update rotational velocity
if (friction.length() > CHAI_SMALL)
{
rotVelocity.add( cMul(-10.0 * increment, cCross(cSub(cursorPos, objectPos), friction)));

// add some damping...
//rotVelocity.mul(1.0 - increment);
// compute the next rotation of the torus

// send forces to haptic device
