Date: september 24th, at 2pm Abstract: NURBS (Non-Uniform Rational Basis Spline) is a mathematical model that has become a standard in the modeling community for generating and representing curves and surfaces. For some specific applications such as computational engineering or real-time rendering, the NURBS surfaces must be converted into isotropic…
Seminar by Konrad Schindler on September 30 (Tuesday) at 11am Title:Piecewise rigid 3D scene flow Abstract: I will present recent work on dense 3D scene flow estimation from stereo video of dynamic environments. The proposed method estimates the depth and 3D motion field of a dynamic scene from multiple…
July 16 at 10:30am in room Byron beige Abstract: A NURBS model is usually created by several NURBS patches (trimmed or untrimmed) stitched together. The unavoidable gaps between trimmed patches have long been an issue in industry. Because many applications, such as manufacturing and physical analysis, do not tolerate gaps,…
Abstract: 4D multiview reconstruction of moving actors has many applications in the entertainment industry and although studios providing such services become more accessible, efforts have to be done in order to improve the underlying technology to produce high-quality 4D contents. In this paper, we enable surface matching for an animated…
Abstract: In this talk, I will present a series of recent works (some of them unpublished) that found unexpected applications to power diagrams (and more generally, power duals of triangulations), including image dithering, masonry design, and Lagrangian fluid simulation. Mathieu Desbrun is the John W. & Herberta M. Miles Professor…
Abstract: We present a method for surface approximation that yields closed surfaces within geometric guarantees. Through refinement we construct a piecewise linear function on a 3D triangulation within the tolerance volume, whose isosurface is an intersection-free surface triangle mesh. Further, the algorithm provides strict guarantees over global approximation error of…
Abstract: Polyhedral meshes are defined as general polygonal meshes with planar faces. These meshes have attracted recent attention, mainly due to their benefits in industrial and architectural design. I will present a framework that provides a parametrization of the deformation shape space of polyhedral meshes. Such parametrization allows for efficient…
Abstract By combining geometric considerations with modern optimization methods and computing power, the research area of Architectural Geometry strives to bridge the gap between creative architectural freeform designs and their efficient realization. In this talk, a set of novel optimization approaches for dealing with three different architecturally motivated optimization tasks…
Seminar given by Csaba Benedek on January 23, 2014 (2pm-3pm, Byron Beige) Abstract: In this talk, we introduce a system for generating 4D video flows from large dynamic scenes by integrating two different types of data: outdoor 4D point sequences measured by a rotating LIDAR sensor, and 4D models of…
By David Bommes In the last years the fascinating evolution of our digital age has resulted in the birth of countless applications that require or work on 3D geometric data. With 3D laser scanners, CAD systems and interactive sculpting tools, today the creation of digital geometry has become comparatively simple…
