A Flexible Multi-Volume Shader Framework for Arbitrarily Intersecting Multi-Resolution Datasets
2007
IEEE Transactions on Visualization and Computer Graphics
Preserved Fulltext
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 ...

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 ...
