Offsetting operations in solid modelling

The range of operations on solids supported by current geometric modelling systems is very limited. Typically, solids represented in a modeller can be transformed by rigid motions and combined by Boolean operations. This paper introduces another family of transformations, called solid offsetting, which map solids into solids. Offset solids are expanded or contracted versions of an original obje...

Solid Modelling in Haskell

We investigate the suitability of the functional model of programming as applied to the solid modelling eld of 3D rendering, with particular reference to expressiveness and e ciency. We nd that functional languages with a good implementation can be more e cient than other languages in certain aspects in the rendering process. Furthermore, recent developments in functional languages allow di cul...

Solid Modelling Techniques

Analytical PDE Solid Modelling

In this paper we study analytical solutions of a fourth order partial differential equation subjected to different boundary conditions of solid modelling, and investigate the effects of various factors in the PDE and boundary conditions on the shape of the generated solids. With the proposed modelling technique, we can easily manipulate and modify the shape of the generated solid by altering a ...

Modelling municipal solid waste generation: a review.

The objective of this paper is to review previously published models of municipal solid waste generation and to propose an implementation guideline which will provide a compromise between information gain and cost-efficient model development. The 45 modelling approaches identified in a systematic literature review aim at explaining or estimating the present or future waste generation using econ...
