Constructor and Description
Bezier3D(float[][] points, int nbrPoints, boolean useZ) Create a Bezier object based on points passed as a 2D array.
Bezier3D(processing.core.PVector[] points, boolean useZ) Create a Bezier object based on an array of vectors.

Method Summary

Modifier and Type	Method and Description
void	force2D() Forces the bezier to ignore the z values i.e. makes it become 2D.
processing.core.PVector	point(float t) Calculate the point for a given parametric point 't' on the curve.
processing.core.PVector[]	points(int steps) Calculate the points along the Bezier curve.

Constructor Detail

Bezier3D

public Bezier3D(float[][] points,
                int nbrPoints,
                boolean useZ)

Create a Bezier object based on points passed as a 2D array.

Parameters:

points - 2D array[point no.][x/y]

nbrPoints - number of points to use from array

useZ - true 3D Bezier : false = 2D Bezier

Bezier3D

public Bezier3D(processing.core.PVector[] points,
                boolean useZ)

Create a Bezier object based on an array of vectors.
The bezier curve will use all of the points in the array.

Parameters:

points - array of control points

Method Detail

force2D

public void force2D()

Forces the bezier to ignore the z values i.e. makes it become 2D.

point

public processing.core.PVector point(float t)

Calculate the point for a given parametric point 't' on the curve.

Parameters:

t -

Returns:

points

public processing.core.PVector[] points(int steps)

Calculate the points along the Bezier curve.

Parameters:

steps - the number of points to calculate

Returns:

array of PVector holding points
