public SpaceCurve()

Method Detail

getDefaultView

public View getDefaultView()

Returns a SpaceCurveView with antialiasing turned on.

Overrides:

getDefaultView in class Exhibit3D

getPointCount

public int getPointCount()

Get the size of the array of points that define this curve. If the array has not yet been computed, because the curve has not yet been drawn, then the return value will be 0.

getPoint

public Vector3D getPoint(int i)

Get one of the points from the array that defines the curve.

Parameters:

i - The index of the point in the array. This must be in the range 0 to getPointCount()-1, or an error will occur.

Returns:

The i-th point from the array. This can be null, indicating a break in the curve.
