Lay summary
The interdisciplinary research area of Geometry Processing
combines concepts from computer science, applied mathematics,
and engineering for the efficient acquisition, reconstruction,
optimization, editing, and simulation of geometric objects.
Applications of geometry processing algorithms can be found
in a wide range of areas, including computer graphics, computer
aided design, geography, and scientific computing. Moreover,
this research field enjoys a significant economic impact as
it delivers essential ingredients for the production of cars,
airplanes, movies, and computer games, for example.

Most of the research so far has concentrated on the efficient
processing of static 3D surfaces (in particular, triangle meshes),
and a number of well-established algorithms exist for interactively
editing, compressing, smoothing, or subdividing this kind of data.
However, some applications (e.g., animation or simulation) are
intrinsically based on the concept of dynamic 3D surfaces, that
is, surfaces with a time-varying geometry or even topology.
Currently, such surfaces are often treated in a discrete way,
as a finite set of static 3D surfaces, and hence they are usually
processed independently of each other with any of the aforementioned
algorithms.

The main idea of this project is to rather consider dynamic 3D
surfaces as an entire and continuous 4D object and to gain advantages
from this point of view. Hence, the goal of the project is to develop
effective strategies and efficient algorithms for processing this
kind of data. In particular, we are interested in methods for
interactively modelling and editing dynamic 3D surfaces. This
poses a number of interesting problems that need to be addressed
and solved, ranging from the reconstruction of dynamic 3D surfaces
from a discrete set of static surfaces, the design of novel data
structures for representing and storing them, to the efficient
visualization of this kind of data.

Abstract

The interdisciplinary research area of Geometry Processing combines concepts from computer science, applied mathematics, and engineering for the efficient acquisition, reconstruction, optimization, editing, and simulation of geometric objects. Applications of geometry processing algorithms can be found in a wide range of areas, including computer graphics, computer aided design, geography, and scientific computing. Moreover, this research field enjoys a significant economic impact as it delivers essential ingredients for the production of cars, airplanes, movies, and computer games, for example. Most of the research so far has concentrated on the efficient processing of static 3D surfaces (in particular, triangle meshes), and a number of well-established algorithms exist for interactively editing, compressing, smoothing, or subdividing this kind of data. However, some applications (e.g., animation or simulation) are intrinsically based on the concept of dynamic 3D surfaces, that is, surfaces with a time-varying geometry or even topology. Currently, such surfaces are often treated in a discrete way, as a finite set of static 3D surfaces, and hence they are usually processed independently of each other with any of the aforementioned algorithms. The main idea of this project is to rather consider dynamic 3D surfaces as an entire and continuous 4D object and to gain advantages from this point of view. Hence, the goal of the project is to develop effective strategies and efficient algorithms for processing this kind of data. In particular, we are interested in methods for interactively modelling and editing dynamic 3D surfaces. This poses a number of interesting problems that need to be addressed and solved, ranging from the reconstruction of dynamic 3D surfaces from a discrete set of static surfaces, the design of novel data structures for representing and storing them, to the efficient visualization of this kind of data. The project is a continuation of the project “InteraktiveModellierung dynamischer 3D-Flächen” under DFG grant HO 2457/2-1, which was granted by the DFG (German Research Foundation) for three years, but then funded for one year only, due to the applicant moving from Clausthal University of Technology to the Università della Svizzera italiana in Lugano.
