VISTA - Scalable Toolkits Volume Renderer

VISTA is a multithreaded, platform independent, scalable and robust volume renderer. It allows users to perform volume rendering of datasets even those that exceed available memory (using out of core paging). VISTA also interfaces with Mesh Viewer for generating transfer functions and custom cameras which can be used to view (render) a volume from different positions. This provides vista the capability of creating walk-thrus of datasets.

Features

Volume Render volumes of any size using out of core paging. (Vista does direct volume rednering using raycasting)
Custom Transfer Function Support
Vista can be linked as library
Vista could be run as a server and used along with Mesh Viewer
Output zbuffer for compositing
Create walk through around data segments
Large Image resolutions - any resolution possible

Render Options

You can specify multiple camera views with --persp, --front, --left, --right, --top, --back, --bottom
The options are additive, so if you put all the above options on the same command line, you will get seven images.
If you don't specify a camera, the default camera is perspective (--persp).
You can also do --spinx, --spiny, or --spinz to get a sequence of images rotating around the axes.
You can change the resolution with -x width -y height options. Default resolution is 320x240
