A Flexible Multi-Volume Shader Framework for Arbitrarily Intersecting Multi-Resolution Datasets

J. Plate, T. Holtkaemper, B. Froehlich
2007 IEEE Transactions on Visualization and Computer Graphics  
We present a powerful framework for 3D-texture-based rendering of multiple arbitrarily intersecting volumetric datasets.  ...  Each volume is represented by a multi-resolution octree-based structure and we use out-of-core techniques to support extremely large volumes.  ...  The two main contributions of our work are an approach for multi-volume rendering for arbitrarily intersecting multi-resolution datasets and a flexible shader framework for specifying the rendering behavior  ...

Interactive volume illumination of slice-based ray casting [article]

Dening Luo
2020 arXiv   pre-print
In this paper, a novel and flexible performance method of slice-based ray casting is proposed to implement the volume illumination effects, such as volume shadow and other scattering effects.  ...  In recent years, the realistic and interactive volume rendering of the global illumination can improve the perception of shape and depth of volumetric datasets.  ...  Meanwhile, combined multi-slice per pass, which reduces the performance overhead of building illumination attenuation buffer, provides a more flexible and scalable framework of volume illumination rendering  ...

Faster Isosurface Ray Tracing Using Implicit KD-Trees

I. Wald, H. Friedrich, G. Marmitt, P. Slusallek, H.-P. Seidel
2005 IEEE Transactions on Visualization and Computer Graphics  
Today, isosurfaces are most often visualized by extracting a polygonal approximation that is then rendered via graphics hardware, or by using a special variant of pre-integrated volume rendering.  ...  However, these approaches have a number of limitations in terms of quality of the isosurface, lack of performance for complex data sets, or supported shading models.  ...  ACKNOWLEDGMENTS We want to thank Ken Moreland and Randy Frank for providing access to the LLNL's Richtmyer-Meshkov data set, and the Visible Human Project for the Visible Female data.  ...
