Class BezierCurve3D

java.lang.Object

toxi.geom.BezierCurve3D

public class BezierCurve3D
extends Object

Standard multi-segment bezier curve implementation with optional automatic handle alignment between segments. Also provides curve tangent calculation feature. Can be used to create closed curves. Usage of this class is very similar to Spline3D.

add

public BezierCurve3D add(Vec3D p)

alignAllHandles

public void alignAllHandles()

alignHandlesForPoint

public void alignHandlesForPoint(int id)

isClosed

public boolean isClosed()

Returns:

true, if the curve is closed. I.e. the first and last control point coincide.

toLineStrip3D

public LineStrip3D toLineStrip3D(int res)

Computes a list of intermediate curve points for all segments. For each curve segment the given number of points will be produced.

Parameters:

res - number of points per segment

Returns:

list of Vec3Ds
