IsoSurf Revision History

Version 1.5c and d - September 2001

  • (d) fixed a bug when reading input files in Windows, and added a high and a low threshold.
  • (c) fixed a bug in thresholding introduced since version 1.5, leading to the generation of mesh-like surfaces.

    • Version 1.5b - August 2001

  • correct treatment of thresholds which exclude all data from any particular slice of the volume.

    • Version 1.5 - May 2001

  • `-a' option added to centralise the output data around the location (0,0,0).
  • If no morphological filtering is used (i.e. `-m n'), the data values are used to locate the cross-section in each slice more precisely. This can result in smoother surfaces when using high resolutions.

    • Version 1.4 - September 2000

  • Co-ordinates of the vertices in the output surface shifted such that they can be registered with the input data array. (0,0,0) is now at the start of the array.
  • More information provided in the error messages.

    • Version 1.3 - June 2000

  • Can now write the surface triangulation in VRML version 1.0 format as well as OOGL format. Added option '-v' for this purpose.
  • Removed artificial limit on the number of maximal discs that can be extracted from each cross-section.

    • Version 1.2 - April 2000

  • Source only update to allow compilation under Windows 95/98/NT.

    • Version 1.1 - August 1999

  • First public release.

    • Version 1.0

  • Original private version.
