VISTA - Scalable Toolkits Volume Renderer

This is the last release; all development has stopped.

VISTA is a multithreaded, platform-independent, scalable and robust volume renderer. It can 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 makes it possible for VISTA to generate dataset walkthroughs.

Features

• Render volumes of any size using out-of-core paging. (VISTA does direct-volume rendering 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 walkthrough 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
