addConvexIntersections

protected boolean addConvexIntersections(double u0,
                                         int f0,
                                         double u1,

                                         int which,
                                         IntersectionList list,
                                         Intersection excludeStart,
                                         Intersection excludeEnd)

getId

public int getId()

Description copied from interface: Volume

Returns the id which has been set by Volume.setId(int). Identifiers are non-negative and should be consecutive starting at zero, so that they can be used as indices into arrays which associate additional information with the volumes. Small gaps in the set of used identifiers are tolerable.

Specified by:

getId in interface Volume

Returns:

id of this volume

operator$and

public Volume operator$and(Volume v)

Description copied from interface: Volume

This operator method creates the intersection of this volume and v.

Specified by:

operator$and in interface Volume

Parameters:

v - a volume

Returns:

the intersection of a and b

See Also:

CSGIntersection

operator$com

public Volume operator$com()

Description copied from interface: Volume

This operator method creates the complement of this volume.

Specified by:

operator$com in interface Volume

Returns:

the complement of this volume

See Also:

CSGComplement

operator$or

public Volume operator$or(Volume v)

Description copied from interface: Volume

This operator method creates the union of this volume and v.

Specified by:

operator$or in interface Volume

Parameters:

v - a volume

Returns:

the union of this volume and v

See Also:

CSGUnion

operator$sub

public Volume operator$sub(Volume v)

Description copied from interface: Volume

This operator method creates the difference between a and b.

Specified by:

operator$sub in interface Volume

Parameters:

v - the volume to be subtracted

Returns:

the difference between this volume and b

See Also:

CSGDifference

setId

public void setId(int id)

Description copied from interface: Volume

Sets a unique identifier for this volume. id has to be non-negative, the ids of all coexisting volumes should be consecutive numbers starting at zero.

Specified by:

setId in interface Volume

Parameters:

id - id for this volume

See Also:

Volume.getId()
