Automatic Stream Surface Seeding
(The Eurographics Association, 2011)
The visualisation of 3D flow poses many challenges. Difficulties can stem from attempting to capture all flow features, the speed of computation, and spatial perception. Streamlines and stream surfaces are standard tools ...
Collision-Driven Volumetric Deformation on the GPU
(The Eurographics Association, 2011)
We present a novel parallel algorithm to animate the deformation of a soft body in response to collision. Our algorithm incorporates elements of physically-based methods, and at the same time, it allows artistic control ...
Crystal Scattering Simulation for PET on the GPU
(The Eurographics Association, 2011)
This paper presents a fast algorithm to simulate inter-crystal scattering to increase the accuracy of Positron Emission Tomography (PET). Theoretically, inter-crystal scattering computation would require the solution of a ...
Feature-Based Mesh Editing
(The Eurographics Association, 2011)
Editing and deformation of irregular meshes have become standard tools in geometric modeling. Most approaches try to preserve low-level differential properties of the surface during editing, whereas the global structure ...
Reconstructing Buildings as Textured Low Poly Meshes from Point Clouds and Images
(The Eurographics Association, 2011)
Current urban building reconstruction techniques rely mainly on data gathered from either laser scans or image- based approaches, and do usually require a large amount of manual post-processing and modeling. Difficulties ...
Separable Approximation of Ambient Occlusion
(The Eurographics Association, 2011)
Ambient occlusion (AO) provides an effective approximation to global illumination that enjoys widespread use amongst practitioners. In this paper, we present a fast easy-to-implement separable approximation to screen space ...
Motion Capture Data Completion and Denoising by Singular Value Thresholding
(The Eurographics Association, 2011)
Human motion is of high articulation and correlation.When a human motion sequence is represented by a matrix, the matrix will be approximately low-rank. This low-rank property has been used by previous manifold-based ...
Efficient Feature-preserving Local Projection Operator for Geometry Reconstruction
(The Eurographics Association, 2011)
This paper proposes an efficient and feature-preserving locally optimal projection operator (FLOP) for geometry reconstruction. We first develop a bilateral weighted local optimal projection operator. We then present a ...
