Detailed Description

Unstructured grid volume mapper based the ZSweep Algorithm.

This is a volume mapper for unstructured grid implemented with the ZSweep algorithm. This is a software projective method.

Background:

The algorithm is described in the following paper: Ricardo Farias, Joseph S. B. Mitchell and Claudio T. Silva. ZSWEEP: An Efficient and Exact Projection Algorithm for Unstructured Volume Rendering. In 2000 Volume Visualization Symposium, pages 91–99. October 2000. http://www.cse.ogi.edu/~csilva/papers/volvis2000.pdf
