TiGL-2.1.2

on GitHub

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
