Method Detail

parameterChanged

public void parameterChanged(Parameter param,
                             java.lang.Object oldValue,
                             java.lang.Object newValue)

Description copied from class: Exhibit

This method will be called automatically when a parameter that has been added to this Exhibit is changed. It should not ordinarily be called directly. Note that in fact, this method simply calls forceRedraw. This method is defined in the <@link Parameterizable} interface.

Specified by:

parameterChanged in interface Parameterizable

Overrides:

parameterChanged in class Exhibit

Parameters:

param - The Parmeter whose value has been set.

oldValue - The previous value of the parameter.

newValue - The new, current value of the parameter. This is not necessarily guaranteed to be different from the old value (although it is for parameters definedin the VMM core).

kappa

protected double kappa(double t)

tau

protected double tau(double t)

frenetODEstep2

protected Vector3D[] frenetODEstep2(double tInitial,
                                    double tFinal,
                                    Vector3D[] initialVal,
                                    int numSubdivision)

Second order method, "Step to midpoint"

frenetODEstep4

protected Vector3D[] frenetODEstep4(double tInitial,
                                    double tFinal,
                                    Vector3D[] initialVal,
                                    int numSubdivision)

makeRepereMobile

public Vector3D[] makeRepereMobile(double t)

Description copied from class: SpaceCurveParametric

Returns an array of four vectors representing the Repere Mobile to the curve at a specified t value. The array has length 4. The first vector is the point on the curve, and the other three vectors are the unit tangent, unit normal, and unit bi-normal to the curve at that point. The return value can be null, if the curve or its first or second derivative is not defined at the specified point. If the return value is non-null, then all four vectors in the returned array are non-null.

Overrides:

makeRepereMobile in class SpaceCurveParametric

value

protected Vector3D value(double t)

Description copied from class: SpaceCurveParametric

Returns a point (x(t), y(t), z(t)) on the curve, given a value of t. The return value can be null, indicating a break in the curve. Subclasses must define this method to specify a particular curve.

Specified by:

value in class SpaceCurveParametric

getUserExhibitSupport

public UserExhibit.Support getUserExhibitSupport()

Description copied from interface: UserExhibit

This method should return a non-null object that is created and customized in the constructor of the class that implements UserExhbit.

Specified by:

getUserExhibitSupport in interface UserExhibit
