  9. fix: code change to fix default cad color drawing (Issue 547).
  10. usability: add key code definitions to the help menu and Appendix C of the User's guide.

• 5.3 (build 2720) - November 23, 2008
  1. enhancement: Add option to draw cell centered slice data. Cell centered data is created by adding the string, CELL_CENTERED=.TRUE. on a &SLCF line in an FDS input file (requires FDS built with svn revision 2690 or later).
  2. enhancement: Optionally hide slice data residing on the coarse mesh portion of a region refined by an imbedded mesh - so that data from both meshes are not displayed simultaneously. (Issue 531).
  3. enhancement - Add option to control placement of scaling ticks (through the Display dialog box) used to document cases.
  4. enhancement - Add menu item and command key equivalent (%) for toggling the projection type. Pressing '%' toggles between perspective and size preserving projection methods for displaying the scene.

The dialog box includes several items such as specifying a custom configuration/.ini file name for later loading by the script, specifying custom render images file names, specifying the render directory. As a result, the edits required to finalize the auto-generated script are minimal.
  6. enhancement: Improve the layout and functionality of the motion dialog box. (Issue 534).
  7. enhancement: Add window size option (1920x1080) to Motion dialog box
  8. fix: hrrpuvcutoff values now clamped down to 1199.99 since hrrpuv 3D file data can ONLY contain hrrpuv's between 0 and 1200. A hrrpuvcutoff value greater than 1200.0 would result in hiding of ALL hrrpuv data. (Issue 524).
  9. fix: fix clipping when displaying cad textures (and devices) - (Issue 536).
  10. fix - fixed the cad texture display and texture file flipping issue by adding the texture origin to the .ge1 file (Issue 522).

• 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.

  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).

  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).
