High-Quality Surface Splatting on Today s GPUs
(The Eurographics Association, 2005)Because of their conceptual simplicity and superior flexibility, point-based geometries evolved into a valuable alternative to surface representations based on polygonal meshes. Elliptical surface splats were shown to allow ... -
Interactive Ray Tracing of Point-based Models
(The Eurographics Association, 2005)Point-based methods have recently gained significant interest, as their simplicity and independence of connectivity make them a simple and powerful tool in both modelling and rendering. Still, their use for high-quality ... -
Normal Estimation for Point Clouds: A Comparison Study for a Voronoi Based Method
(The Eurographics Association, 2005)Many applications that process a point cloud data benefit from a reliable normal estimation step. Given a point cloud presumably sampled from an unknown surface, the problem is to estimate the normals of the surface at the ... -
Point Sampling with Uniformly Distributed Lines
(The Eurographics Association, 2005)In this paper we address the problem of extracting representative point samples from polygonal models. The goal of such a sampling algorithm is to find points that are evenly distributed. We propose star-discrepancy as a ... -
A Practical Structured Light Acquisition System for Point-Based Geometry and Texture
(The Eurographics Association, 2005)We present a simple and high-quality 3D scanning system based on structured light. It uses the common setup of a video projector, a computer-controlled turntable and a single camera. Geometry is acquired using a combination ... -
Progressive Splatting
(The Eurographics Association, 2005)Surface splatting enables high quality and efficient rendering algorithms for dense point-sampled datasets. However, with increasing data complexity, the need for multiresolution models becomes evident. For triangle meshes, ... -
Robust Filtering of Noisy Scattered Point Data
(The Eurographics Association, 2005)In this paper, we develop a method for robust filtering of a noisy set of points sampled from a smooth surface. The main idea of the method consists of using a kernel density estimation technique for point clustering. ... -
A Sampling Theorem for MLS Surfaces
(The Eurographics Association, 2005)Recently, point set surfaces have been the focus of a large number of research efforts. Several different methods have been proposed to define surfaces from points and have been used in a variety of applications. However, ... -
Surface Reconstruction with Enriched Reproducing Kernel Particle Approximation
(The Eurographics Association, 2005)There are many techniques that reconstruct continuous 3D surfaces from scattered point data coming from laser range scanners. One of the most commonly used representations are Point Set Surfaces (PSS) defined as the set ... -
A Unified Lagrangian Approach to Solid-Fluid Animation
(The Eurographics Association, 2005)We present a framework for physics-based animation of deforming solids and fluids. By merging the equations of solid mechanics with the Navier-Stokes equations using a particle-based Lagrangian approach, we are able to ... -
Voronoi Rasterization of Sparse Point Sets
(The Eurographics Association, 2005)Point-based representations are becoming increasingly common in computer graphics, especially for visualizing data sets where the number of points is large relative to the number of pixels involved in their display. When ...
