The ImageVis3D team is proud to announce the release of ImageVis3D 1.1!

ImageVis3D is a desktop volume rendering application which was designed to visualize large data. Support is available for multiple rendering modes, such as 1D and 2D transfer functions, isosurface rendering, as well as specialized modes such as MIP and slice views. On modern systems, ImageVis3D's GPU-accelerated rendering delivers incredible performance, while compatibility options exist to allow ImageVis3D to perform adequately on older systems.

While ImageVis3D 1.1 is primarily a feature release, important bugs were fixed. Changes since 1.0 include:

New Features

  • A converter for Fraunhofer EZRT data was contributed by AndrĂ© Liebscher. Thanks, AndrĂ©!
  • The 'minimum framerate' setting is now honored; ImageVis3D will now render higher-resolution data if they exist in cache and your system can render the data at the desired framerate.
  • The 'a' key now changes rotation modes; see the manual for details.
  • 'pageup' and 'pagedown' now provide fine-grained control over the zoom factor.
  • One can now zoom in the 2D transfer function editor.

Bugs fixed in this release

  • Full-color datasets with multiple bricks would render incorrectly with the slice-based renderer.
  • A bug was fixed which caused the crash detection feature not to disable itself once enabled.
  • Built-in URLs for help/other resources were updated to account for the new SCI website.

Changes which are only of interest to developers

  • The windows project file now disables many of the warnings in the included third party libraries.
  • Tuvok's IO has been separated into a separate repository and linked via a subversion external.

Known issues with this release

  • The 'Stack' ("stk"), single-file TIFF volume, Fraunhofer EZRT ("rek") and Brick-of-values ("BOV") file formats can only be read, not written.
  • RGBA is the only kind of multicomponent data supported.
  • For some Linux systems with nvidia GPUs, the raycaster can expose a driver issue which causes system lockups. We recommend sticking with the slice based volume renderer on Linux for this release.
  • Full-color datasets do not display a proper histogram in the transfer function editors.


ImageVis3D 1.1 supports Intel Macs 10.4 and up (10.5.7 highly recommended), Windows, and Linux. Binaries are available at:
