This paper introduces an extension of a general framework that allows the simulation of various mechanical models (discrete or continuous ones, for different kinds of meshes, in any dimension). This framework relies on a topological model and a rule-based language, that performs sub-gra...

The concept of a visualization pipeline is central to many applications providing scientific visualization. In practical usage scenarios, when the pipelines fuse multiple datasets and combine various visualization methods they can easily evolve into complex visualization networks directing data flow.&...

The recognition of dynamic gestures of hands using pure geometric 3D data in real-time is a challenge. RGBD sensors simplified this task, giving an easy way to acquire 3D points and track them using the depth maps information. But use this collection of raw 3D points ...

Real time ray tracing has been given a lot of attention in recent years in the academic and research community. Several novel algorithms have appeared that parallelize different aspects of the ray tracing algorithm through the use of a GPU. Among these, the creation of Bo...

Glyphs have proven to be a powerful visualization technique for general tensor fields modeling physical phenomena such as diffusion or the derivative of flow fields. Most glyph constructions, however, do not provide a way of considering the temporal derivative, which is generally nonzer...

This paper presents an efficient algorithm for a global parameterization of triangular surface meshes. In contrast to previous techniques which achieve global parameterization through the optimization of non-linear systems of equations, our algorithm is solely based on solving at most two li...

We present a method for generating shell-like objects such as surgical guides and plates from segmented computed tomography (CT) images, using signed distance fields and constructive solid geometry (CSG). We develop a userfriendly modeling tool which allows a user to quickly design such...

Current virtual reality (VR) training simulators of liver punctures often rely on static 3D patient data and use an unrealistic (sinusoidal) periodic animation of the respiratory movement. Existing methods for the animation of breathing motion support simple mathematical or patient-specific, esti...
