Efficient Visibility Encoding for Dynamic Illumination in Direct Volume Rendering
Found in: IEEE Transactions on Visualization and Computer Graphics
By Joel Kronander,Daniel Jönsson,Joakim Löw,Patric Ljung,Anders Ynnerman,Jonas Unger
Issue Date:March 2012
pp. 447-462
We present an algorithm that enables real-time dynamic shading in direct volume rendering using general lighting, including directional lights, point lights, and environment maps. Real-time performance is achieved by encoding local and global volumetric vi...
 
Boundary Aware Reconstruction of Scalar Fields
Found in: IEEE Transactions on Visualization and Computer Graphics
By Stefan Lindholm,Daniel Jonsson,Charles Hansen,Anders Ynnerman
Issue Date:February 2015
pp. 1
In visualization, the combined role of data reconstruction and its classification plays a crucial role. In this paper we propose a novel approach that improves classification of different materials and their boundaries by combining information from the cla...
 
Verifying Volume Rendering Using Discretization Error Analysis
Found in: IEEE Transactions on Visualization and Computer Graphics
By Tiago Etiene,Daniel Jonsson,Timo Ropinski,Carlos Scheidegger,Joao L. D. Comba,Luis Gustavo Nonato,Robert M. Kirby,Anders Ynnerman,Claudio T. Silva
Issue Date:January 2014
pp. 140-154
We propose an approach for verification of volume rendering correctness based on an analysis of the volume rendering integral, the basis of most DVR algorithms. With respect to the most common discretization of this continuous model (Riemann summation), we...
