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.
