NAME

Photonic::Geometry::FromB

VERSION

version 0.021

SYNOPSIS

     use Photonic::Geometry::FromB;
     my $g=Photonic::Geometry::FromB->new(B=>$pdl);
     my $B=$g->B;
     my $G=$g->G;

DESCRIPTION

Creates a geometry object to be used in a Photonic calculation from a characteristic function B. B is a pdl that takes the values 0 for each pixel or voxel within material A and 1 within material B.

Consumes Photonic::Roles::Geometry. Please see it for attributes.

METHODS

• new(B=>$pdl[, L=>$L] [,units=>$units])

  Creates a new Ph::G::FromB object

  $pdl is a boolean array with 1's and 0's representing the characteristic function within the unit cell. Its dimensions must be odd. Its number of dimensions is the dimension of space

  $L is the size of the unit cell along the cartesian axes. By default, it is the number of pixels.

  $units is an ndarray with the directions of the basis vectors of the lattice. $units(i,n) is the i-th coordinate of the n-th basis vector. By default, it is given by the cartesian directions.
