Volume Ray Casting with Peak Finding and Differential Sampling
Found in: IEEE Transactions on Visualization and Computer Graphics
By Aaron Knoll, Younis Hijazi, Rolf Westerteiger, Mathias Schott, Charles Hansen, Hans Hagen
Issue Date:November 2009
pp. 1571-1578
Direct volume rendering and isosurfacing are ubiquitous rendering techniques in scientific visualization, commonly employed in imaging 3D data from simulation and scan sources. Conventionally, these methods have been treated as separate modalities, necessi...
Volume rendering with multidimensional peak finding
Found in: Visualization Symposium, IEEE Pacific
By Natallia Kotava,Aaron Knoll,Mathias Schott,Christoph Garth,Xavier Tricoche,Christoph Kessler,Elaine Cohen,Charles D. Hansen,Michael E. Papka,Hans Hagen
Issue Date:March 2012
pp. 161-168
Peak finding provides more accurate classification for direct volume rendering by sampling directly at local maxima in a transfer function, allowing for better reproduction of high-frequency features. However, the 1D peak finding technique does not extend ...
Combined surface and volumetric occlusion shading
Found in: Visualization Symposium, IEEE Pacific
By Mathias Schott,Tobias Martin,A.V. Pascal Grosset,Carson Brownlee,Thomas Hollt,Benjamin P. Brown,Sean T. Smith,Charles D. Hansen
Issue Date:March 2012
pp. 169-176
In this paper, a method for interactive direct volume rendering is proposed that computes ambient occlusion effects for visualizations that combine both volumetric and geometric primitives, specifically tube shaped geometric objects representing streamline...
