  1. fix - Circular Tour was missing from Tour menu. Fix by adding Show Tours menu when there is only one Tour. (Issue 412).

• 5.2 (build 2039) - July 17, 2008
  1. enhancement - Add an option to speed up smoke visualization by using the graphics programming unit (GPU) to perform some of the needed computations. This option is not supported on Linux or Mac OSX releases of Smokeview. The option is turned off by default and may be toggled on and off by pressing the 'G' key.
  2. enhancement - add the ability to run Smokeview in a batch or unattended mode. This mode may be used to automatically load a data file, view it from a prescribed direction and render the resulting image. This may be repeated for other views and/or other data files. A script named casename.ssf may be executed by typing

     smokeview -runscript casename

     at a command line or from the Load/Unload>Script Options menu. Scripts are created by adding desired commands to a text file named casename.ssf or by turning on the script recorder found in the Load/Unload>Script Options menu.

  3. enhancment - internal change in smokeview resulting in reduced memory requirements when loading large cases.
  4. enhancement - When performing WUI computations, allow slice and vector slice files to conform to a specified distance above the ground or terrain.

• 5.1.4 (build 1635) - May 5, 2008
  1. enhancement - save smooth blockages to a file so that their definition may be read in rather than re-calculated.
  2. enhancement - add an option to simplify file compression by compressing only files that were selected for auto-loading.
  3. enhancement - save the size preserving or perspective projection state in the .ini file (Issue 331).
  4. enhancement - implement the "AUTOTERRAIN" keyword for WUI applications of FDS. If all blockages are used to implement terrain (ie no blockages are used to represent buildings on the terrain), then AUTOTERRAIN is used to signal Smokeview to draw a smooth surface representing the terrain.
  5. enhancement - add option to toggle slice file offset - (Issue 348).
  6. enhancement - add support for skipping particle frames created by FDS 5 or later. (Issue 350).
  7. fix - For particle files created by FDS 5, remove the particle skip option as it is no longer supported. (Issue 350).
  8. fix - change a conversion factor from 256*128 to 256*128-1 to avoid a "short int" overflow. Otherwise, some particles may be drawn outside the solution domain. (Issue 323).
  9. fix - fix the 't' toggle when the grid is turned on. (Issue 334).
  10. fix - force smooth blockages to be drawn opaquely to prevent drawing artifact errors when drawn with smoke. (Issue 329).
  11. fix - Fix drawing when smoke, iso and slice routines have non-increasing time steps. This could occur when FDS is restarted to an earlier time than was saved in these data files. (Issue 317).
  12. fix - fix drawing of text on the colorbar (Issue 325).

• 5.1.3 (build 1501) - March 26, 2008

  5. fix - fix problem with running smokezip (caused by imbedded blanks in the path name) from Smokeview (issue 283)
  6. fix - fix problem with menu disconnects (issues 263).
