dims: tuple representing z,y,x dimensions of the desired labelled output
points: 3 x number of points array of floats
points: number of points x 3 array of floats
List of points that define the vertices of the tetrahedra in Z,Y,X format.
These points are referred to by line number in the connectivity array
connectivity: 4 x number of tetrahedra array of integers
connectivity: number of tetrahedra x 4 array of integers
Connectivity matrix between points that define tetrahedra.
Each line defines a tetrahedron whose number is the line number + 1.
Each line contains 4 integers that indicate the 4 points in the nodePos array.
