FluoRender 2.16

We are excited to announce the 2.16 release of FluoRender. For Microsoft
Windows users, FluoRender 2.16 incorporates minor feature improvements and
issue fixes. However, we have upgraded all graphics functions, conforming to
the OpenGL core profile specifications. It allows us to have continuous
support for future graphics processing units. FluoRender 2.16 requires
graphics cards with a minimum support of OpenGL 3.3. Older graphics hardware
need to be replaced. For Apple Mac OS X users, there is the exciting news that
all features previously exclusive to Windows are now available*. It still
requires relatively recent Apple hardware (2009 and on) and the operating
systems.

These issues were fixed:

1. It sometimes did not read an LZW-compressed, RGB channel TIFF file
   correctly.

These improvements were included:

1. The calculation of the depth attenuation has been improved, which is based
   on the data size from current viewing direction. A higher contrast can be
   achieved by increasing the attenuation factor. The depth attenuation effect
   now also supports mesh data.
2. It allows users to change the text and color of measurement tools,
   including locators and rulers.
3. It supports True-type fonts in the render view. You can change the settings
   for font and size in the setting dialog. You can also copy your own True-type
   font file to the installation directory to let FluoRender use it.
4. OpenGL core profile version and GLSL version can be selected in the
   FluoRender setting file.
5. The documentation of tutorials was updated to include new features as well
   as a chapter on movie export.

• Ten-bit output requires capable hardware and may not be available for Apple
  computers.

Note: FluoRender 2.16 was officially announced on May-26, 2015. We had put a
test version on-line earlier than this date, so that the new functions,
especially on Mac OS X, could be tested. If you happen to download the 2.16
version prior to the official release, please download it again.

Last but not least, we would like to thank Ken Calderone from the University
of Michigan, who suggested the improvements including modifiable text for
measurement tools, font, and text size settings. We appreciate the continuous
support from our users. Please let us know if you have any comments.

FluoRender 2.15.3

We are pleased to announce the release of the version 2.15.3 of FluoRender.
This version fixed several issues from previous releases, most of which were
related to the large data streaming mode.

These issues were fixed:

1. Exporting movies with the large data streaming on may write incomplete
   results;
2. View port capturing and key frame animations may stop working with the
   large data streaming on;
3. Incorrect effect rendering (shading and/or shadowing) may occur with the
   large data streaming on;
4. Multiple channels may be rendered incorrectly with the large data streaming
   on;
5. Paint-selected masks may be rendered incorrectly with the large data
   streaming on;
6. Large data may be clipped at high zoom ratios.

Additionally, we included a new feature in this version:

1. It now allows users to select one GPU for dedicated OpenCL calculations
   when multiple OpenCL-capable GPUs are installed and activated in the system.
   GPU selection is done by typing its ID in the FluoRender setting file.

Please see FluoRender's online manual and tutorials for more details.

We would like to thank Dr. Bindokas from the University of Chicago, who
pointed out most of the issues listed above and helped us test the new
versions. We appreciate any issue report and suggestion from the users. Please
take our online survey, which can be downloaded at the same website as
FluoRender (www.fluorender.org).

Thanks for your continued support of FluoRender!

FluoRender 2.15.2

These issues were fixed:

1. It failed to read a TIFF file with multiple strips when saved with LZW
   compression.
2. Memory leaks when multiple GPUs were installed and an OpenCL kernel was
   used.
3. A volume data set could not be compressed with OpenGL RG texture
   compression.
4. The application icon looked jagged under Windows.
5. Rulers were not saved in a project file.
6. Applying paint brush strokes on a data set larger than 4 GB caused
   FluoRender to crash. After fixing, it performs best on the latest graphics
   cards with 12 GB of memory (Geforce GTX Titan X or Quadro K6000).

These improvements are included:

1. When the keyboard shortcuts for the paint brush tool are used, it allows
   single mouse clicking to select/unselect a circular region.
2. Speed of applying a paint brush stroke is significantly improved,
   especially for large data on slow computers.

These new features are included:

1. A probe tool to create a two-point ruler along the viewing direction. When
   used in combination with the paint brush tool (via key board shortcut), it
   creates a cylindrical selection along the ruler.
2. A profile tool to calculate intensity profiles along rulers. This tool is
   best used along with the probe tool to generate an averaged intensity profile
   within the cylindrical mask region.

YouTube or Vimeo.

Release Notes

New Features

1. OpenCL kernel editor
   New in the 2.15 release of FluoRender, an OpenCL kernel editor is added to the
   tool collection. The editor can be accessed from menu->Tools->OpenCL kernel
   editor. It allows users to create, load, edit, and save an OpenCL kernel for
   3D image processing. Active kernel is applied to selected channel when the
   “Run” button is pressed. A list of built-in kernels are also provided for
   basic 3D filtering operations. See Chapter 19 of the user's manual for more
   details.
2. Automatic threshold estimation for paint brush
   New in the 2.15 release of FluoRender, threshold for paint brush can be
   estimated by applying brush strokes. The estimation is based on the local
   histogram of the data under the first applied stroke. Its calculation is
   performed with an OpenCL kernel. See Chapter 14 of the user's manual for more
   details.

Improvements include UI updates and bug fixes. More importantly, we edited a
user's manual that covers all the latest features of FluoRender in great
detail.

FluoRender

This is the Initial release of FluoRender v2.14. The source files are more recent than the binaries, due to delayed release here on Git.
