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


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.


  • new(B=>$pdl[, L=>$L])

    Creates a new Ph::G::FromB object

    $pdl is a boolean array with 1's and 0's representing the characteriztic 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.

ACCESORS (read only)

  • B

    The characteristic function as PDL

  • L

    Unit cell sizes as a B->ndims pdl.
