This TiGL Release was published on 17/04/2014.

  • Changed API:
    • The returned UID strings of the following functions must not be freed by the user anymore:
      • tiglWingGetOuterSectionAndElementIndex
      • tiglWingGetInnerSectionAndElementUID
      • tiglFuselageGetStartSectionAndElementUID
      • tiglFuselageGetEndSectionAndElementUID
      • tiglWingComponentSegmentPointGetSegmentEtaXsi
      • tiglWingComponentSegmentFindSegment
    • Changed behavior of tiglWingComponentSegmentFindSegment. In case the specified point does not lie within 1 cm of any segment, TIGL_NOT_FOUND is returned.
    • Changed behavior of tiglWingComponentSegmentPointGetSegmentEtaXsi. If the specified point lies outside any segment so that the transformation can not be executed, TIGL_MATH_ERROR is returned.
    • The following API functions tiglComponentIntersectionPoint, tiglComponentIntersectionPoints and tiglComponentIntersectionLineCount are deprecated and will be removed in future releases. These functions are replaced by new intersection routines.
    • Removed functions tiglExportStructuredIGES and tiglExportStructuredSTEP
  • General changes:
    • Completely reworked boolean operations with the following effects:
      • Fusing the whole plane is faster in many cases and more reliable
      • We keep track of the origins of each trimmed face which helps for the IGES and STEP exports
      • The boolean operations can be debugged now by setting the environment variable TIGL_DEBUG_BOP
    • Completely rewritten STEP and IGES exports:
      • Each face has now an identifier name
      • Inclusion of intersection curves
      • Inclusion of far fields into exports
      • IGES export in non-BREP mode since it is not supported by CATIA
    • Added new demos for C, Python and MATLAB. Please look into the documentation how to run them.
    • Added function for the intersection computation of a geometrical shape with a plane
    • Experimental implementation of wing and fuselage guide curves
    • The mathematical orientation of wing profiles is checked for correctness
    • TiGL requires now at least OpenCASCADE 6.6.0
    • Ported to OpenCASCADE 6.7.0
  • New API functions:
    • Added new API functions for shape/shape and shape/plane intersections:
      • tiglIntersectComponents
      • tiglIntersectWithPlane
      • tiglIntersectGetLineCount
      • tiglIntersectGetPoint
  • Fixes:
    • Fixed a bug in tiglWingComponentSegmentFindSegment
    • Fixed numerical inaccuracy in the projection of points to a wing segment
    • Fixed crash in case of too long UIDs
    • Fixed some memory leaks
  • TiGLViewer:
    • Improved IGES import:
      • Multiple shapes are now imported as separate shapes from IGES files.
      • Fixed wrong scaling when importing IGES files.
    • Improved STEP export:
      • Files are now exported in units of meters instead of millimeters.
    • Improved BREP export and import: compound objects are now decomposed to separate objects.
    • Added method to export fused aircraft to BREP
    • Added method to export wing and fuselage profiles and guide curves to BREP
    • Fixed incorrect units in IGES and STEP export from save-as dialog.
    • General save-as dialog: All visible objects are saved to the file, if no shape is selected. Otherwise, only the selected objects are exported.
    • Added debugging parameters to settings dialog. This includes:
      • Adapting number of displayed iso lines per face
      • Display face numbers
      • Debug boolean operations (if enabled, debugging shapes in BRep format are stored to the current working directory)
    • Added new dialog for shape/shape and shape/plane intersections.
    • Added drag and drop support to TiGLViewer. Files (CPACS, IGES, STEP, BREP) are opened when they are dragged into TiGLViewer.
    • TiGLViewer displays far field after calculating the trimmed aircraft
    • Iso U/V lines are no longer displayed by default. This can be changed in the settings dialog.
    • The fused/trimmed aircraft geometry is displayed using a different color for each component.
    • Added visualization of wing and fuselage guide curves.
    • Fix: Only the first intersection curve was displayed. This is fixed now.
    • New icons
