ImageVis3D 1.3
================
The ImageVis3D team is proud to announce the release of ImageVis3D 1.3!
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 1.3 is a major release, bringing many new features and a
great number of bugfixes. Changes since 1.2 include:
New Features
------------
* Long running operations (such as capturing rotations) can now be
cancelled.
* (Temporarily) allow LoadDataset to be 'interactive' in scripting
mode, which allows conversion of raw data in this mode.
* The maximum brick size used is now a configurable parameter in the
settings. This brings us a step closer to supporting integrated
Intel chipsets.
* "Capture mode", which is enabled when capturing a rotation or
scripting ImageVis3D, will now always render the data at its native
resolution.
* Page up/Page down can be used to move a slice 10% through the
dataset. Use the mouse wheel for fine-scale positioning.
* ImageVis3D can now quantize data down to 8bit when exporting to
ImageVis3D Mobile.
Bugs fixed in this release
--------------------------
* A Mac-only crash which could occur while closing a render window
was fixed.
* Instead of crashing(!), users are warned when their video card
lacks the needed 3D texture size, and asked if they want to proceed
at their own risk.
* A bug was fixed loading some types of embedded JPEGs in DICOMs.
* Clip planes now properly respect relative locking.
* The progress viewer is now kept up to date while capturing a
rotation.
* Mouse wheel rotations were normalized when iterating through slice
views, in particular to ensure that "mighty mouse" Mac mice will not
scroll too quickly.
* Interaction with ImageVis3D Mobile was added to the manual's
documentation.
* Reset ("r") now properly resets window sizes in 2x2 mode.
* ImageVis3D now draws circular control widget for all controllable
points in the "Basic" mode 2D transfer function editor, instead of
just the first few.
* Fixed a bug in the rotation direction when capturing a MIP rotation
for some views.
* A bug was fixed rendering iso-surfaces when in 2x2 mode.
* Capturing a "sequence frame" in previous versions could, in some
circumstances, append an incorrect number. The semantics were
updated slightly to make the "last saved image number" detection
more robust.
* Directories which do not open will not be closed; in rare cases,
this used to cause crashes on Mac systems.
* ImageVis3D is now more forgiving for the case of converting
multiple different files at the same time.
* Fix loading/conversion of unsigned 16bit data (silently/accidently
truncated to 12 bits in 1.2).
* Use the correct dataset scaling factors when exporting to IV3D
Mobile.
* Conversion of RGBA datasets was fixed by updating the calculation
of the size of a UVF data block.
* The Fraunhofer EZRT ("REK") converter was updated to remove
assumptions of machine and data file endianness.
Changes which are only of interest to developers
------------------------------------------------
* The "Upload" button was removed from the debug log UI. The
anonymous error reports it produced were never useful.
* The version of Qt used was upgraded to 4.6.0.
* Some documentation was added to the repository on how to define
your own converter. Users will need to build ImageVis3D from source
for this.
* Many Tuvok classes were (finally) moved into the "tuvok" namespace.
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.
* RGBA is the only kind of multicomponent data supported.
* NVIDIA GPUs on both Linux and Macs 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
on Mac and Linux for this release.
* Full-color datasets 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.
* The ClearView lens does not position itself properly when the
screen is in low-res mode to achieve faster rendering.
* On some systems, making a render window larger does not in and of
itself does not cause the window to update its rendering. As a
workaround, dragging the window or opening a menu forces an update.
ImageVis3D 1.3 supports Intel Macs 10.5 and up (10.5.8 highly
recommended), Windows, and Linux. Binaries are available at:
