DLR-SC/tigl 2.0.5

on GitHub

Released: 11/06/2013

• Changed API:
  • Switched to const char ** strings
  • tiglWingGetSegmentIndex returns now also the wing index instead of asking for it
  • Removed TiGL wire algorithms switching functions. Now a Bspline wire is used for each profile.
• General Changes:
  • Symmetry modeling
  • Explicit modeling of the wing leading edge to improve tesselated output (no more leading edge bumps)
  • Explicit modeling of the wing upper and lower shape
  • The fuselage lofting now creates a smooth surface without hard edges (due to fixed OpenCASCADE bug)
  • Completely rewritten VTK export:
    • Full body export including wing segment metadata
    • Fixed lots of errors.
    • Large improvement of calculation times.
    • Provides wing segment metadata in a proper VTK-way, to allow visualization of these data in VTK viewers. Calculation and export of the proper normal vectors.
  • IGES and STEP export with CPACS metadata
  • Collada export for use in 3D rendering programs like Blender
  • MATLAB bindings for TiGL!
  • Completeley rewritten python bindings (e.g. better support for arrays)
  • Added logging framework to write outputs into log files (google-glog)
  • Ported to OpenCASCADE 6.6.0
• New API functions:
  • tiglWingComponentSegmentGetMaterialUIDs, to query materials on component segment
  • tiglWingComponentSegmentGetPoint, to query cartesian point on the wing component segment (on chord surface)
  • tiglWingSegmentPointGetComponentSegmentEtaXsi, to compute segment to component segment coordinates
  • tiglWingComponentSegmentGetSegmentUID, queries the uids of the ith segment of the component segment
  • tiglWingComponentSegmentGetNumberOfSegments, queries the number of segments belonging to a component segment
  • tiglExportFuselageColladaByUID
  • tiglExportWingColladaByUID
  • tiglExportStructuredIGES
  • tiglExportStructuredSTEP
  • tiglConfigurationGetLength, returns the length of the airplane
  • tiglWingGetSpan, returns the wing span
  • tiglComponentIntersectionPoints (convenience function, vectorizes tiglComponentIntersectionPoint to improve speed)
  • tiglExportMeshedGeometryVTKSimple and tiglExportMeshedGeometryVTKSimple (replaced dummy implementation)
• Fixes:
  • Intersection calculation used by tiglComponentIntersectionPoint
  • Fixed incorrectly placed fuselage positionings
  • Fixed tiglWingComponentSegmentFindSegment returning segments that don't belong to the component segment
  • Workaround to buggy OpenCASCADE boolean fuse algorithms (which seems to be non-commutative). As a result, the fusing of the whole plane can be slower than before.
  • Removed warning about missing component segments
• TiGLViewer:
  • Display user defined component segment point
  • Improved speed of intersection calculation
  • Improved speed of shape triangulation
  • Display upper and lower shape of the wing
  • Display of the full model incorporating the symmetry properties of the CPACS components
  • Fixed detection, if CPACS file is changed while displayed in TiGLViewer
  • An optional control file can steer some basic settings like tesselation/triangulation accuracy (e.g. to tune speed of cpacs file opening)
  • STEP export
  • Settings Dialog (tesslation accuracy settings, background...)
  • New icon and color scheme
