ReduceM: Interactive and Memory Efficient Ray Tracing of Large Models
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a novel representation and algorithm, ReduceM, for memory efficient ray tracing of large scenes. ReduceM exploits the connectivity between triangles in a mesh and decomposes the model into triangle strips. We ...
Accelerating Ray Tracing using Constrained Tetrahedralizations
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
In this paper we introduce the constrained tetrahedralization as a new acceleration structure for ray tracing. A constrained tetrahedralization of a scene is a tetrahedralization that respects the faces of the scene geometry. ...
Fast Soft Self-Shadowing on Dynamic Height Fields
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a new, real-time method for rendering soft shadows from large light sources or lighting environments on dynamic height fields. The method first computes a horizon map for a set of azimuthal directions. To reduce ...
Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that typically requires only a single render pass ...
Free Form Incident Light Fields
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
This paper presents methods for photo-realistic rendering using strongly spatially variant illumination captured from real scenes. The illumination is captured along arbitrary paths in space using a high dynamic range, ...
Provably Good 2D Shape Reconstruction from Unorganized Cross-Sections
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
This paper deals with the reconstruction of 2-dimensional geometric shapes from unorganized 1-dimensional cross-sections. We study the problem in its full generality following the approach of Boissonnat and Memari [BM07] ...
Computing Local Signed Distance Fields for Large Polygonal Models
(The Eurographics Association and Blackwell Publishing Ltd., 2008)
The signed distance field for a polygonal model is a useful representation that facilitates efficient computation in many visualization and geometric processing tasks. Often it is more effective to build a local distance ...
Automatic Detection and Visualization of Distinctive Structures in 3D Unsteady Multi-fields
(The Eurographics Association and Blackwell Publishing Ltd., 2008)
Current unsteady multi-field simulation data-sets consist of millions of data-points. To efficiently reduce this enormous amount of information, local statistical complexity was recently introduced as a method that identifies ...
Generating Color Palettes using Intuitive Parameters
(The Eurographics Association and Blackwell Publishing Ltd., 2008)
Color is widely used in data visualization to show data values. The proper selection of colors is critical to convey information correctly. In this paper, we present a technique for generating univariate lightness ordered ...
