DUODECIM - A Structure for Point Scan Compression and Rendering
(The Eurographics Association, 2005)
In this paper we present a compression scheme for large point scans including per-point normals. For the encoding of such scans we introduce a particular type of closest sphere packing grids, the hexagonal close packing ...
Point-based Surface Rendering with Motion Blur
(The Eurographics Association, 2004)
In this paper we show how to extend point-based surface rendering to illustrate object motion. We do this by first extruding the circular points into ellipsoids, which fill the space traced out by the points in motion. ...
A Dynamic Surface Reconstruction Framework for Large Unstructured Point Sets
(The Eurographics Association, 2006)
We present a method to reconstruct simplified mesh surfaces from large unstructured point sets, extending recent work on dynamic surface reconstruction. The method consists of two core components: an efficient selective ...
Interactive Editing of Large Point Clouds
(The Eurographics Association, 2007)
This paper describes a new out-of-core multi-resolution data structure for real-time visualization and interactive editing of large point clouds. In addition, an editing system is discussed that makes use of the novel data ...
Interactive Global Light Propagation in Direct Volume Rendering using Local Piecewise Integration
(The Eurographics Association, 2008)
A novel technique for efficient computation of global light propagation in interactive DVR is presented in this paper. The approach is based on a combination of local shadows from the vicinity of each voxel with global ...
Interactive 3D Painting on Point-Sampled Objects
(The Eurographics Association, 2004)
We present a novel painting system for 3D objects. In order to overcome parameterization problems of existing applications, we propose a unified sample-based approach to represent geometry and appearance of the 3D object ...
Multi-Resolution Sound Rendering
(The Eurographics Association, 2004)
Point-based multi-resolution representations have been used successfully for rendering highly complex three dimensional scenes in real-time. In this paper, we apply this paradigm to sound rendering: A hierarchy of stochastic ...
Topological estimation using witness complexes
(The Eurographics Association, 2004)
This paper tackles the problem of computing topological invariants of geometric objects in a robust manner, using only point cloud data sampled from the object. It is now widely recognised that this kind of topological ...
Perceptually Guided Rendering of Textured Point-based Models
(The Eurographics Association, 2006)
In this paper, we present a textured point-based rendering scheme that takes into account the masking properties of the human visual system. In our system high quality textures are mapped to point-based models. Given one ...
Octree-Based Progressive Geometry Coding of Point Clouds
(The Eurographics Association, 2006)
We propose a generic point cloud encoder that compresses geometry data including positions and normals of point samples corresponding to 3D objects with arbitrary topology. In this work, the coding process is led by an ...
