Reconstruction dynamique de surface par convection géométrique

In this paper, we present a selective and evolutive method for reconstructing a surface from a point cloud that makes it possible to produce a simplified triangulated surface and to update it dynamically in an efficient manner. This method is based on a geometric convection algorithm and extends recent work on dynamic surface reconstruction introduced in (Allègre et al., 2005). We present a new...

Utilização de técnicas de análise estática e dinâmica para otimização de aplicações de propósito geral em GPUs

We have witnessed large advances in the use of devices designed speci cally for running parallel applications. Examples of this class of hardware are graphics processing cards, as those produced by NVIDIA. The use of GPUs to accelerate general purpose applications gave rise to a new line of parallel applications development, popularly known as GPGPU. Although recent, GPGPU applications achieved...

Détection de structure géométrique dans les nuages de points. (Geometric structure detection in point clouds)

In this short chapter, we introduce some of the objects that will be used throughout the thesis: the distance functions, projection functions and medial axes. We survey some known result concerning the local regularity of medial axis (eg. Hausdorff dimension, rectifiability), a few of which come from the semi-concavity of the distance function. The compilation of these results complements the s...
