Field Detail

x

public double x

The x coordinate

y

public double y

The y coordinate

z

public double z

The z coordinate

re

public double re

The real component.

im

public double im

The imaginary component.

Method Detail

isInvalid

public final boolean isInvalid()

Determines whether this vertex is invalid, i.e has invalid coordinates value.

Returns:

true if this vertex is invalid

projection

public final java.awt.Point projection()

Gets the 2D projection of the vertex.

Returns:

the 2D projection

project

public final void project()

transform

public final void transform()

Transforms coordinate values to fit the scaling factor of the projector. This routine is only used for transforming center of projection in Surface Plotter.
