Variational Volumetric Surface Reconstruction from Unorganized Points
(The Eurographics Association, 2007)Reconstruction of smooth surfaces from point sets is an important problem in many applications since this sort of data often appear in real-life scenarios. This paper presents method for solving this this problem at ... -
Simultaneous GPU-Assisted Raycasting of Unstructured Point Sets and Volumetric Grid Data
(The Eurographics Association, 2007)In the recent years the advent of powerful graphics hardware with programmable pixel shaders enabled interactive raycasting implementations on low-cost commodity desktop computers. Unlike slice-based volume rendering ... -
Applications of Optimal Sampling Lattices for Volume Acquisition via 3D Computed Tomography
(The Eurographics Association, 2007)There has been mounting evidence that the familiar Cartesian lattices, while convenient for signal processing and representation, are sub-optimal when it comes to signal fidelity. More suitable in this respect are optimal ... -
Feature Enhancement using Locally Adaptive Volume Rendering
(The Eurographics Association, 2007)Classical direct volume rendering techniques accumulate color and opacity contributions using the standard volume rendering equation approximated by alpha blending. However, such standard rendering techniques, often also ... -
Palette-Style Volume Visualization
(The Eurographics Association, 2007)In this paper we propose a palette-style volume visualization interface which aims at providing users with an intuitive volume exploration tool. Our system is inspired by the widely used wheel-style color palette. The ... -
Quality Enhancement of Direct Volume Rendered Images
(The Eurographics Association, 2007)In this paper, we propose a new method for enhancing the quality of direct volume rendered images. Unlike the typical image enhancement techniques which perform transformations in the image domain, we take the volume data ... -
3D Reconstruction of Emission and Absorption in Planetary Nebulae
(The Eurographics Association, 2007)This paper addresses the problem of reconstructing the 3D structure of planetary nebulae from 2D observations. Assuming axial symmetry, our method jointly reconstructs the distribution of dust and ionized gas in the nebulae ... -
Accelerated Light Propagation Through Participating Media
(The Eurographics Association, 2007)Monte Carlo path tracing is a simple and effective way to solve the volume rendering equation. However, propagating light paths through participating media can be very costly because of the need to simulate potentially ... -
Efficient Ambient and Emissive Tissue Illumination using Local Occlusion in Multiresolution Volume Rendering
