Geometric Modelling of Hyperpatches

Daniela Velichová ; Mechanical Engineering Faculty, Slovak Technical University, Bratislava, Slovakia

Abstract

The paper deals with the modelling of solids (hyperpatches) on the basis of their creative laws. Creative representation of a solid enables to modell also solids with "curve-like" edges, not only solids with the polyhedral boundary as in the boundary representation method. There is provided also the possibility to control a non-homogeneous distribution of the interior points of a solid created as an interpolated figure. Basic notions such as a solid cell, an isoparametric curve segment and an isoparametric surface patch, or tangent space and density vector in a solid point are described and their relevance to the intrinsic geometric properties of the solid is discussed. Composite solid modelling problems on adjoining of the elementar solid cells are mentioned.
