DLR-SC/tigl v2.1.3

TiGL-2.1.3

on GitHub

TiGL 2.1.3 was released on 08/12/2014. Merry Christmas!

• Changed API:
  • Changed functions tiglWingGetSegmentSurfaceArea to exclude side faces and trailing edges
  • Removed functions tiglWingGetUpperPointAtAngle and tiglWingGetLowerPointAtAngle. These functions were replaced by tiglWingGetUpperPointAtDirection and tiglWingGetLowerPointAtDirection.
• General changes:
  • Support for global transformation (translation refType="absGlobal"). Notice: some (incorrect) CPACS models will now look differently.
  • Accurate B-Spline approximation of CST curves using Chebychev approximation.
  • Implemented recursive fusing trimming for the use of e.g. bellyfairings. Added small cpacs example how to model a bellyfairing.
  • Implemented trimming of intersection curves with parent bodies and far fields
  • Improved computation of fuselage positionings. This should improve loading times of configurations with large number of sections, since the algorithmic complexity is reduced.
  • IGES + STEP export: All wing faces are now classified as Top-Wing, Bottom-Wing, or Trailing-Edge.
  • IGES export: Changed units to mm.
  • IGES export: Implemented layers/levels .
  • The OCAF framework is no longer required to build TiGL.
  • The build system now uses the cmake config-style TiXI and OCE search mechanisms.
• New API functions:
  • Added functions to get the B-Spline paramterization of fuselage and wing profiles:
    • tiglProfileGetBSplineCount, returns the of B-Splines a profile is built of.
    • tiglProfileGetBSplineDataSizes, returns the size of the knot vector and the number of control points of one profile B-Spline.
    • tiglProfileGetBSplineData, returns the knot vector and the control points.
  • Added functions tiglWingGetSectionCount and tiglFuselageGetSectionCount
  • Added functions tiglWingGetSegmentUpperSurfaceAreaTrimmed and tiglWingGetSegmentLowerSurfaceAreaTrimmed to e.g. compute the surface area of a control device.
  • Added functions tiglWingGetChordPoint and tiglWingGetChordNormal to query points on the wing chord surface.
  • Added functions tiglWingGetUpperPointAtDirection and tiglWingGetLowerPointAtDirection.
• Fixes:
  • Fixed tiglWingComponentSegmentGetPoint in case of global wing transformations.
  • Fixed tiglWingComponentSegmentGetPoint bug, returning eta values > 1 (issue 107).
  • Fixed numerical inaccuracy of tiglWingGetPointDirection
  • Fixed incorrect CST curves at for N2 < 1.
  • Fixed null pointer bug in IGES export.
• TiGLViewer:
  • Highly improved scripting console:
    • Script file can be given as command line argument (using option --script)
    • Added function to export all objects to file
    • The main application objects can be scripted (i.e. app, app.viewer, app.scene)
    • Draw shapes, points and vectors from script
    • Make screenshots by command
    • Context menu for copy-paste actions
    • History with recent commands
    • Mouse support
    • More wrapped tigl functions
    • Improved stability
    • Exception handling
    • TiXI errors and warnings are printed on the console now
  • Added dialog to draw points and vectors.
  • Added dialog for screenshot settings, including option for white background.
  • JPEG and PNG support for background images.
  • Collada export for the complete configuration (i.e. support for multiple objects).
  • Cleanup of menu entries.
  • Fixed multiple opened CPACS documents in TiGLViewer.
  • Fixed 3D view flickering on Mac OS X with Qt 4.8.6.
  • Language bindings:
    • Added python 3 support of tiglwrapper.py
    • Improved TiGL library loading error messages in python wrapper
    • New Java bindings. Hand-written high level API not yet complete (not all TiGL functions wrapped). Low level API (autogenerated) can be used instead for unimplemented functions.
    • Added Java example (see share/doc/tigl/examples/JavaDemo.java)
  • Documentation:
    • Added chapter for TiGL Viewer and the TiGL Viewer scripting console.
