In our approach to volume modeling, we combine volume representations by voxel data and by continuous real functions. The figures above illustarte:\\
a) sweeping by a volumetric head;\\
b) head cut by a moving cutter;\\
c) hair growth and styling on the voxel head.

One of the main problems is the function-to-voxel and voxel-to-function conversion. The following paper discusses the conversion between two representations and gives several examples of their useful combination:
