about vvis

vvis is designed to render 3D scalar fields, i.e. volume data collected by medical applications. It can handle several file formats like the format of the University of Erlangen (used by OpenQVis) and the format of the University of Heidelberg (used by the non-opensource program Vrend). It can also produce such files from a series of TIFF images. To display the volume different algorithms are available: texture method, texture method using preintegration, raycasting, raycasting using preintegration and shear warp.

demo datasets

For demo datasets look at OpenQVis page. Corresponding transfer functions can be found in the data subdirectory of the source tarball.
