Method Detail

isBounded

public boolean isBounded()

Description copied from class: AbstractShape

Returns true if the shape is of limited space

Specified by:

isBounded in class QuadricSurface

Returns:

Boundedness of this shape.

getRasterPoints

public PointND[] getRasterPoints(int number)

Description copied from class: AbstractShape

Rasters the shape with a given number of points or less. If the shape is not bounded null is returned.

Overrides:

getRasterPoints in class QuadricSurface

Parameters:

number - the number of points

Returns:

the raster points

getPrincipalAxis

public Axis getPrincipalAxis()

Specified by:

getPrincipalAxis in class SimpleSurface

applyTransform

public void applyTransform(Transform t)

Description copied from interface: Transformable

Applies the Transform t to the object.

Specified by:

applyTransform in interface Transformable

Overrides:

applyTransform in class SimpleSurface

Parameters:

t - the transform to apply to the object.

tessellate

public AbstractShape tessellate(double accuracy)

Description copied from class: AbstractSurface

Creates a list of connected triangles that can be used to approximate the object. The maximal point to mesh error is given as accuracy.

Specified by:

tessellate in class AbstractSurface

Parameters:

accuracy - the maximal deviation in [mm]

Returns:

the compound shape of triangles.

getRadius

public double getRadius()

getCenter

public PointND getCenter()

getRasterPoints

public float[] getRasterPoints(int elementCountU,
                      int elementCountV)

Overrides:

getRasterPoints in class SimpleSurface
