FCRectLat3: Generator of 3D face-centered rectangular lattices as VecLat...
In pgs: Precision of Geometric Sampling

Description Usage Arguments Details Value See Also Examples

Create an object of class "VecLat" representing a 3D face-centered rectangular vector lattice.

1	FCRectLat3(d=1,dx=sqrt(2)*d,dz=d)

`d`	the distance between two neighbour diagonal locations on the horizontal plane. Default: 1.
`dx`	the distance between two neighbour locations along the x-axis on the horizontal plane. Default: sqrt(2)d*.
`dz`	the vertical spacing between two neigbour horizontal planes. Default: d.

Note that the default arguments do not define a face-centered cubic lattice. A face-centered rectangular lattice is considered as a series of horizontal quincunx 2D lattices. The arguments d and dx define the spacings of the horizontal quincunx. The default values of d and dx yields unit horizontal quincunx lattices. A quincunx lying in a given horizontal plane is shifted halfway in a single direction into the next horizontal plane. The argument dz defines the distance separating two consecutive horizontal planes. The unit face-centered cubic lattice is obtained with d=sqrt(2)/2, dx=1 and dz=0.5.
