==================
ImageVis3D 2.0.1
==================
The ImageVis3D team is proud to announce the release of ImageVis3D
2.0.1!
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.
ImageVis3D 2.0.1 is a minor release, concentrating mostly on bugfixes.
Changes since 2.0 include:
New Features
------------
* Tweaked default lighting parameters to default to more desirable
settings.
* Antialias the 1D histogram.
* Leave a couple pixels unused in the histogram backing the 1D
transfer function editor. This makes it easier to see if the minimum
and/or maximum values in a data set are skewing the vertical scale
significantly.
Bugs fixed in this release
--------------------------
* Do more intelligent quantization when we receive floating point
data which is just a series of flags.
* ImageVis3D will (once again) reuse in-memory data if the same data
set is opened in multiple windows.
* Normals are now read from PLY files.
* Fixed a prompt asking to leave 2x2 mode when enabling stereo.
* Histogram scale parameters are now saved per-dataset
* Clip plane state is now copied when cloning a window.
* 1D Transfer function libraries are now usable on Mac+Linux.
Changes which are only of interest to developers
------------------------------------------------
* Visual Studio 2010 support, if you rebuild Qt with VS2010.
Known issues with this release
------------------------------
* The 'Stack' ("stk"), single-file TIFF volume, and Fraunhofer EZRT
("rek") file formats can only be read, not written.
* The 'Brick Of Values' (BOV) reader does not support BOVs in which
the data are split across multiple files.
* RGB[A] are the only kinds of multicomponent data supported.
* NVIDIA GPUs on Linux expose a driver issue which can hang the
system for prolonged periods of time. To workaround this issue, we
recommend sticking with the slice based volume renderer Linux for
this release.
* Full-color data sets do not display a proper histogram in the
transfer function editors.
* In any mode but MIP, the `Recorder' always uses the highest resolution
data, regardless of any other settings.
* In the "Disable LOD" mode of MIP Recordings, progress information
is not given. Progress is being made; a visibly-correct rendering is
not required to create an on-disk image which is visibly correct.
* All data are linearly interpolated; for data sets consisting solely
of 'flags', this is undesirable.
ImageVis3D 2.0 supports Intel Macs 10.5 and up (10.6.7 highly
recommended), Windows, and Linux. Binaries are available at:

or you can get the source directly from our subversion repository,
using the 'svn' command:
svn co
https://gforge.sci.utah.edu/svn/imagevis3d
or any other subversion client. We look forward to your feedback on
this release. Best,
- The ImageVis3D team.
