Detailed Description

Make the union of 2 or more regions.

Intended use:

Public interface

Prerequisite

Synopsis

The LCUnion class is a specialization of class LCRegion. It makes it possible to extend a LCRegion along straight lines to other dimensions. E.g. a circle in the xy-plane can be extended to a cylinder in the xyz-space. includes the union border. It can only be used for a lattice of any dimensionality as long as the dimensionality of the (hyper-)union matches the dimensionality of the lattice.

The center of the union must be inside the lattice

const LCRegion region8 = 0,
const LCRegion region9 = 0,
const LCRegion region10 = 0 
)

Construct from multiple regions.

When takeOver is True, the destructor will delete the given regions. Otherwise a copy of the regions is made.
