The ImageVis3D team is proud to announce the release of ImageVis3D 1.1.1!

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 1.1.1 is primarily a bugfix release, some new features were added. Changes since 1.1 include:

New Features

  • A new 'basic' mode was added to the 2D transfer function editor. This mode more closely matches the look and feel of editors from earlier SCI tools. Users may click the 'Expert' button to use the earlier editor.
  • Diffuse lighting was changed to use a two-sided lighting model (the volume is now backlit in addition to front-lit).
  • Added keyboard shortcuts for most operations in ImageVis3D.
  • The mouse wheel can now be inverted in the settings dialog.

Bugs fixed in this release

  • Detection of out of memory conditions was enhanced. ImageVis3D will notice when the rendering library is running out of memory, even if it hasn't hit the user-set limit, and adjust memory usage accordingly.
  • Fixed a bug which prevented the stereo widget from being closed when no dataset was loaded.
  • Another round of updates for URLs as they find more permanent homes on the new SCI website.
  • Workaround for a Qt bug that caused events to be delivered while a window was being destroyed.
  • Scaling issues were fixed in the 2D transfer function editor.

Changes which are only of interest to developers

There were no changes of note for this category.

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