A Hybrid GPU Rendering Pipeline for Alias-Free Hard Shadows
(The Eurographics Association, 2009)We present a new GPU pipeline for rendering per-pixel exact shadows that are cast by point lights and parallel lights. Our approach is hybrid in that it uses kD-tree accelerated ray-tracing to determine shadow-ray ... -
Hybrid Ambient Occlusion
(The Eurographics Association, 2009)Ambient occlusion captures a subset of global illumination effects, by computing for each point of the surface the amount of incoming light from all directions and considering potential occlusion by neighboring geometry. ... -
GPU Ray-Casting for Scalable Terrain Rendering
(The Eurographics Association, 2009)With the ever increasing resolution of scanned elevation models, geometry throughput on the GPU is becoming a severe performance limitation in 3D terrain rendering. In this paper, we investigate GPU ray-casting as an ... -
RASTeR: Simple and Efficient Terrain Rendering on the GPU
(The Eurographics Association, 2009)This paper introduces RASTeR, a GPU based LOD technique for interactive rendering of large terrains based on a paired multi-resolution tree structure. Our approach uses regular height-data blocks and terrain independent ... -
Visualization Framework for the Integration and Exploration of Heterogeneous Geospatial Data
(The Eurographics Association, 2009)This paper presents an interactive visualization framework for heterogeneous geospatial data developed in context of an interdisciplinary research project that aims at the risk analysis of sea-dumped chemical weapons in ... -
A web-enabled Geovisual Analytics tool applied to OECD Regional Data
(The Eurographics Association, 2009)Recent advances in web-enabled graphics technologies have the potential to make a dramatic impact on developing highly interactive Geovisual Analytics applications for the Internet. An emerging and challenging application ... -
Supporting Interactive Haptic Shaping of 3D Geologic Surfaces with Deformation Property Painting
(The Eurographics Association, 2009)Meshes made from 3D points are used to represent many important geoscience concepts such as the surface of the earth (topography), rock strata (horizons) and faults. When creating a complex computer model, a geoscientist ... -
Geo-Spatial Context-Aware Visualization
(The Eurographics Association, 2009)Mobile computer systems equipped with wireless communication and sensor technology-such as mobile phones with cameras-have become widely available. Context information, for example the user's current location or their ... -
Visualizing Heterogeneous Utility Data: A Case for Aesthetic Design
(The Eurographics Association, 2009)A map visually enfolds selected messages to a target audience. To achieve this effectively, a clear understanding of 'the message, the user and the purpose' of the map needs to be translated into successful design choices ...
