Real Flow/Houdini Extensions-Change Log

• January, 8, 2006
  *** Official release of the Real Flow SOPs on sourceforge. ***
  1) Cleaned up error handling in the RF Export and Import SOP
  2) BUG FIX: Sometimes when exporting an SD or particle files, the first time
  the "Write RF Particles" button is pressed, the file is corrupt.
  When pressing the button again, all is good even though nothing has
  been changed in the Houdini setup.
  3) The texture attributes for particles and meshes are now "uv" only.
  4) The velocity attribute for partcles and meshes are now "v" only.
  5) ROP temporarily unavailble, needs more Houdini 8 related changes.
• March 20, 2005: v0.98.5.3
  SOP_RF_Export:
  1) Fixed file name problem when exporting BIN2 particle files.
  2) All SD files will have a 0-(nframes-1) frame range.
  SOP_RF_Import:
  ROP_RealFlow:
  1) All SD files will have a 0-(nframes-1) frame range.
• February 17, 2005: v0.98.5.2
  SOP_RF_Export:
  1) Added support for texture maps in SD files. Set the detail string attribute "sd_obj_tex_fname" to the absolute
  path to the texture file for RF to read (the texture file name field in the GUI has been removed).
  UV coordinates are exported to the SSD file as well.
  SOP_RF_Import:
  ROP_RealFlow:
  1) Added support for texture maps in SD files. Set the detail string attribute "sd_obj_tex_fname" to the absolute
  path to the texture file for RF to read (the texture file name field in the GUI has been removed).
  UV coordinates are exported to the SSD file as well.
  2) Fixed bug related to deforming geomtetry disappearing in Real Flow.
  3) Better error checking for non triangular polygons.
• January 2, 2005: v0.98.4 -
  SOP_RF_Export:
  1) Changed the zero based SD file export rule to accommodate start frames
  greater than 0 (start frames can not be less than zero).
  2) Added HTML help pages (still needs more editing).
• December 26, 2004: v0.98.3 -
  SOP_RF_Export:
  1) Now exports SD file format for Real Flow 3
  2) Particle files are now version 8 (Real Flow 3)
  3) Particle file now use Real Flow 3 fluid types
  4) There is now a menu to select matrix or vertex mode when exporting a SD file
  SOP_RF_Import:
  1) Mesh velocity and attributes are now vectors (instead odf 3 floats )
  2) Particle velocity, Norman and force attributes are now vectors (instead of 3 floats )
  3) Speed improvements
  4) Particle and mesh velocity, texture and normals attributes have corresponding Houdini
  attributes (v, uv, N).
  RF_ROP:
  1) Now exports SD file format for Real Flow 3 (vertex mode disabled until Real Flow 3
  conversion complete ).
  2) Bug fixed in the way the vertex count was calculated when more than one object is exported,
• December, 5, 2004
  Fixed frame range problem in GUI of SOP_RF_Export and set beginning frame in the Real Flow
  ROP to start at frame 0 to match Real Flow's starting frame.
• November 25, 2004 -
  SOP_RF_Export: New "Apply Object Transformations" switch;
  when checked the transformations made at the OBJ level for the SOP is used to
  transform the geometry to the Real Flow SD file. XformOrder fixed too.
  SOP_RF_Import: Now supports multiple objects (up to 255) in a Real Flow SD
  file. There are 2 new toggles, "Apply Object Transformations" which will
  apply the SD files object t/r/s vectors to the geometry and "Apply CG
  Transformations" which will apply the SD file's CG t/r vectors to the geometry.
• Sept, 12, 2004 - Fixed matrix transformations for exported SD files. Now
  supports Red Hat 9, Fedora Core 2 and Houdini 7.
• July 31, 2004-Added multiple inputs to the SOP_RF_Export SOP.
• June 28, 2004 - Added Real Flow particle BIN file export to the RF_Export_SOP

• May 4, 2004 - Compiled with HDK 6.5 (except IRIX)
• April 24, 2004 - Completed SD file import (for Real Wave surfaces and dynamics)
• November 4, 2003 - Incorporated new file format changes for Real Flow 2.5
• October 10, 2003 - Created version for Houdini 6.1
