Abstract

We present our approach to volume modelling which combines volume representations by voxel data and by continuous real functions. We discuss the main differences between direct volume visualization and modelling with voxel data, questions of conversion between two representations including volume reconstruction from contour data. We illustrate the approach by several advanced operations on a volumetric object: set-theoretic operations, sweeping, hypertexturing, feature-based sculpting, splitting, spatial and temporal transformations
