Dynamic Modeling With Implicit Surfaces and Polygonal Meshes
"Morse theory reveals the topological structure of a shape based on the critical points of a real function over the shape. This thesis solves a relaxed form of Laplace's equation to find a ""fair"" Morse function with a user-controlled number and configuration of critical points."

System Design and Analysis for Creating a 3D Virtual Street Scene for Autonomous Vehicles Using Geometric Proxies from a Single Video Camera
… to other representations such as lightweight polygonal meshes. In addition, 3D point clouds can be difficult for a human to visually understand as the data points do not always form a naturally coherent object.</p> <p>This paper introduces a system to lower the memory consumption needed for …

Scalable Methods for Processing Massive Geometric Meshes
Polygonal meshes are easily the most common surface representation currently employed in computer graphics, finding application in fields as diverse as the visual arts and scientific computation. Technological advances in the areas of three-dimensional scanning, digital storage, and computer …

Procedural authoring of solid models
… from one or more input surfaces, such as scanned polygonal meshes, CAD models or implicit surfaces. Furthermore, the resulting model can be easily modified using sculpting and simulation tools, such as the Finite Element Method or particle systems, which are embedded as operators in the language. …

Failure processes in soft and quasi-brittle materials with nonhomogeneous microstructures
… mesh induced artifacts, we consider unstructured polygonal finite elements. A randomly-seeded polygonal mesh leads to an isotropic discretization of the problem domain, which does not bias the direction of crack propagation. However, polygonal meshes tend to limit the possible directions a crack …

Accurate geometry reconstruction of vascular structures using implicit splines
… the underlying shape is usually expressed as polygonal meshes or in parametric forms, which is very inconvenient for implementing ramification of branching. As a result, the reconstructed geometries are not suitable for computer aided diagnosis and computer guided minimally invasive vascular …

The polyhedral Gauss map and discrete curvature measures in geometric modelling.
… discrete surfaces in space, represented as polygonal meshes, the TAC is measured by means of the Polyhedral Gauss Map (PGM) of vertices. This is a representation of the curvature of a vertex as an area on the surface of a sphere. Positive and negative components of the curvature of a vertex …
