|
ijk_to_xyz
|
ijk_to_xyz ( self, ijk )
A matrix ijk corresponds to a point in xyz space.
This function maps the matrix index to the xyz point.

self,
m,
origin,
size,

|
|
xyz_to_ijk
|
xyz_to_ijk ( self, xyz )
A matrix ijk corresponds to a point in xyz space.
This function maps the xyz point to the matrix index.
The returned matrix index need not be integers.

|
|
read_matrix
|
read_matrix (
self,
ijk_origin=None,
ijk_size=None,
ijk_step=None,
progress=None,
)
Must overide this function in derived class to return a 3 dimensional
NumPy matrix. The returned matrix has size ijk_size and
element ijk is accessed as m[k,j,i]. It is an error if the requested
submatrix does not lie completely within the full data matrix. It is
also an error for the size to be <= 0 in any dimension. These invalid
inputs might throw an exception or might return garbage. It is the
callers responsibility to make sure the arguments are valid.
