Method Detail

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

deriv1

protected Vector3D deriv1(double t)
Description copied from class: SpaceCurveParametric
Finds the derivative (x'(t),y'(t),z'(t)) at a given point on the curve. This class defines the derivative using an approximation based on nearby points on the curve. While this is probably good enough, subclasses can override this if they want, to provide an exact formula for the derivative. The return value can be null if the curve or its derivative is undefined at the specified value of t.

Overrides:
deriv1 in class SpaceCurveParametric

deriv2

protected Vector3D deriv2(double t)
Description copied from class: SpaceCurveParametric
Finds the second derivative (x''(t),y''(t),z''(t)) at a given point on the curve. This class defines the second derivative using an approximation based on nearby points on the curve. While this is probably good enough, subclasses can override this if they want, to provide an exact formula for the derivative. The return value can be null if the curve or its second derivative is undefined at the specified value of t.

Overrides:
deriv2 in class SpaceCurveParametric
