In spite of the widespread use of CAD systems for design and CAE systems for analysis, the
two processes are not well integrated because CAD and CAE models inherently use …

Solid modeling is a consistent set of principles for mathematical and computer modeling of
three-dimensional solids. The collection evolved over the last thirty years, and is now mature …

Non-manifold boundary representations have gained a great deal of popularity in recent
years and various representation schemes have been proposed because they allow an …

Recently, three-dimensional CAD systems based on feature-based solid modeling
techniques have been widely used for product design. However, when part models …

While CityGML permits us to represent 3D city models, its use for applications where spatial
analysis and/or real-time modifications are required is limited since at this moment the …

We address the problem of representing and processing non-regular, non-manifold two-
dimensional simplicial meshes, that we call triangle-segment meshes, at different levels of …

In this work, it is presented a complete set of operators, called Morse operators, to build and
unbuild any combinatorial orientable &dimensional manifolds embedded in R”(n 3 3). Also …

While many systems and standards like CAD systems or CityGML permit the user to
represent the geometry and the semantics of building interior models, their use for …

This paper presents a new approach to model complex heterogeneous objects with
simultaneous geometry intricacies as well as complex material distributions. Different from …

The aim of this paper is to provide a review of the characteristics of 3D solid modeling
software libraries–otherwise known as' geometric modeling kernels' in non-manifold …
