Scalable Scene Flow From Point Clouds in the Real World

Implicit Scene Modelling from Imprecise Point Clouds

In applying optical methods for automated 3D indoor modelling, the 3D reconstruction of objects and surfaces is very sensitive to both lighting conditions and the observed surface properties, which ultimately compromise the utility of the acquired 3D point clouds. This paper presents a robust scene reconstruction method which is predicated upon the observation that most objects contain only a s...

Manhattan-World Urban Reconstruction from Point Clouds

Real-Time Global Illumination in Point Clouds

In this paper we present a real-time global illumination approach for illuminating scenes containing huge point clouds. Our GI approach is based upon the distribution of Virtual Point Lights (VPLs) in the scene, which are then used for the indirect illumination of the scene geometry, using Imperfect Shadow Maps for visibility calculation of the VPLs. We are able to render multiple indirect ligh...

Modeling and Visualization of Clouds from Real World Data

Visualization of gaseous phenomena, such as smoke, fire or clouds has been a challenging issue in computer graphics due to the complicated geometry of such natural objects. In the early 80's, approaches that faced this problem tried to simplify the representation of such geometry, using simple particles or ellipsoids. During the last decade work was done on rendering fractal volumes and random ...
