Generalized solids of revolution introduce new possibilities to modeling. Although the process of generalization brings some difficulties, most of them can be avoided by carefully chosen parameters (including proper division into segments). Special variants, in contrast to general form, suffer less from modeling problems. They offer some additional functionality in exchange of some modeling possibilities.
Generalized solids of revolution bring new ways of modeling. It offers wide range of possibilities in copying of reality and also in computer arts. In fact, our new method combines - as the shell example shows - the desirable properties of modeling, special (procedural) modeling and functional representation (F-rep).
There are still open ways of research (for example using axes with negative weights).
