Alternatively, we can split the 3D array into three 2D arrays, one for each colour channel. Note, this is different from above where we kept the entries as RGB vectors, where just two entries were 0.

A set of python programs to make a map (2D or 3D). This repository contains python programs for using simple x, y and z co-ordinates to plot the results in either 2D (only x and y) and in 3D (x, y and ...

This library provides a data structure, Sparse, which represents 3D volumetric data and supports a subset of np.ndarray features.
