Constructor Details

OrderNQuat4dConverger

public OrderNQuat4dConverger(int pOrder,
 int pConvergenceInterval,
 Solver pSolver)

Constructor.

Parameters:

pOrder - the order of the converger

pConvergenceInterval - the length of the convergence interval, in milliseconds

pSolver - the differential equation solver to use

Method Details

setValueAndDerivatives

public void setValueAndDerivatives(javax.vecmath.Quat4d value,
 javax.vecmath.Vector3d[] derivatives,
 long referenceTime)

Sets the value and derivatives associated with this converger. This method changes the state of the converger immediately, without converging to the new values.

Parameters:

value - the value of the variable

derivatives - an array containing the values of the variable's derivatives; the value at index 0 is the first derivative, the value at index 1 is the second derivative, and so on

referenceTime - the referenceTime at which the values were valid

getValue

public void getValue(long time,
 javax.vecmath.Quat4d result)

Returns the current value of the variable.

Parameters:

time - the current time, in milliseconds since the epoch

result - a Vector3d to hold the result

getDerivatives

public void getDerivatives(long time,
 javax.vecmath.Vector3d[] result)

Fills the given array with the current values of the variable's derivatives. The value at index 0 will be set to the first derivative, the value at index 1 will be set to the second derivative, and so on (up to the size of the array).

Parameters:

time - the current time, in milliseconds since the epoch

result - an array to contain the current values of the variable's derivatives

convergeTo

public void convergeTo(javax.vecmath.Quat4d value,
 javax.vecmath.Vector3d[] derivatives,
 long referenceTime,
 long currentTime)

Smoothly converges to the specified state.

Parameters:

value - the value of the variable

derivatives - an array containing the values of the variable's derivatives; the value at index 0 is the first derivative, the value at index 1 is the second derivative, and so on

referenceTime - the time at which the values were valid

currentTime - the current time, in milliseconds since the epoch
