BCRectLat3 {pgs} | R Documentation |
Create an object of class "VecLat"
representing a 3D
body-centered rectangular vector lattice.
BCRectLat3(dx=1,dy=dx,dz=dx)
dx |
spacing along the x-axis. Default: 1. |
dy |
spacing along the y-axis. Default: dx. |
dz |
spacing along the z-axis. Default: dy. |
Note that default parameter values do not define a body-centered cubic lattice. A 3D body-centered rectangular lattice is considered as a series of horizontal 2D rectangular vector lattices. The arguments dx and dy define the spacings in the horizontal planes. A 2D rectangular lattice seen in a given horizontal plane is shift halfway (in both horizontal directions) in the next plane. The argument dz defines the distance between consecutive horizontal planes. Therefore in order to define a (unit) body-centered cubic lattice, one should set dz=0.5.
