"patch('Faces',F,'Vertices',V) creates one or more polygons where V specifies vertex values and F defines which vertices to connect. Specifying only unique vertices and their connection matrix can reduce the size of the data when there are many polygons. Specify one vertex per row in V. To create one polygon, specify F as a vector. To create multiple polygons, specify F as a matrix with one row per polygon. Each face does not have to have the same number of vertices. To specify different numbers of vertices, pad F with NaN values."
In my experience, the much harder part is figuring out what to connect between layers. It is not uncommon to have a larger object slice on one layer than on the next, and larger object slices have more points around the perimeter, so you might have more perimeter points on one slice than on the next slice.
