Constructor Detail

SurfaceVertex

public SurfaceVertex(float ix,
                     float iy,
                     float iz)

The constructor of SurfaceVertex. The x and y coordinated must be in normalized form, i.e: in the range -10 .. +10.

Parameters:

ix - the x coordinate

iy - the y coordinate

iz - the z coordinate

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 Point projection(Projector projector)

Gets the 2D projection of the vertex.

Returns:

the 2D projection

transform

public final void transform(Projector projector)

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

invalidate

public static void invalidate()

Invalidates all vertices. This will force the projector to recalculate vertex projection.

setProjector

public void setProjector(Projector projector)

Sets the projector to project this vertex.

Parameters:

projector - the projector

getProjector

public Projector getProjector()
