The process of building a volumetric model of a single pyramidal neuron from its polygonal mesh. The polygonal mesh model in (a) is converted to a volumetric shell with surface voxelization in (b) and a filled volume with solid voxelization in (c). In (d), the spines are integrated to the volume. The images in (e), (f), (g) and (h) are close ups for the renderings in (a), (b), (c) and (d) respectively. Notice the overlapping shells of the different branches and the soma that result due to the surface voxelization step in (f). In (g), the volume created with solid voxelization reflects a continuous, smooth and high fidelity representation of the entire neuron
