Method Detail

evaluate

public double evaluate(int frame,
              int valuePart)

This method evaluates the data for the specified frame. The Y value is returned.

Parameters:

frame - the frame for which the value is being calculated

valuePart - this param specifies wheather we should return the X, Y or Z part of the result value; it should have one of the following values: X_VALUE - the X factor of the result Y_VALUE - the Y factor of the result Z_VALUE - the Z factor of the result

Returns:

the value of the curve

getLastFrame

public int getLastFrame()

This method returns the frame where last bezier triple center point of the bezier curve is located.

Returns:

the frame number of the last defined bezier triple point for the curve

getType

public int getType()

This method returns the type of the bezier curve. The type describes the parameter that this curve modifies (ie. LocationX or rotationW of the feature).

Returns:

the type of the bezier curve

getRadius

public double getRadius(int bezierTripleIndex)

The method returns the radius for the required bezier triple.

Parameters:

bezierTripleIndex - index of the bezier triple

Returns:

radius of the required bezier triple

getControlPoints

public java.util.List<com.jme3.math.Vector3f> getControlPoints()

This method returns a list of control points for this curve.

Returns:

a list of control points for this curve.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
