• General changes:
  • Support for generic aircraft systems (by Jonas Jepsen).
  • External components are now conforming with the CPACS 2.3 standard (by Jonas Jepsen).
  • Support for rotorcraft (by Philipp Kunze).
  • Improved IGES export: Added support for long names in IGES (more than 8 characters as before).
  • Removed support for RedHat 5 and Ubuntu 13.10.
  • Added support for RedHat 7.
  • Ported to OpenCASCADE 6.9.0 and 7.0.0.
• New API functions:
  • tiglWingComponentSegmentComputeEtaIntersection: This function should be used to compute points on the wing
    that lie on a straight line between two given points.
  • tiglFuselageGetIndex to compute the index based on the fuselage UID.
  • Added new API functions for rotors and rotor blades:
    • tiglGetRotorCount
    • tiglRotorGetUID
    • tiglRotorGetIndex
    • tiglRotorGetRadius
    • tiglRotorGetReferenceArea
    • tiglRotorGetTotalBladePlanformArea
    • tiglRotorGetSolidity
    • tiglRotorGetSurfaceArea
    • tiglRotorGetVolume
    • tiglRotorGetTipSpeed
    • tiglRotorGetRotorBladeCount
    • tiglRotorBladeGetWingIndex
    • tiglRotorBladeGetWingUID
    • tiglRotorBladeGetAzimuthAngle
    • tiglRotorBladeGetRadius
    • tiglRotorBladeGetPlanformArea
    • tiglRotorBladeGetSurfaceArea
    • tiglRotorBladeGetVolume
    • tiglRotorBladeGetTipSpeed
    • tiglRotorBladeGetLocalRadius
    • tiglRotorBladeGetLocalChord
    • tiglRotorBladeGetLocalTwistAngle
• Fixes:
  • Fixed parent-child transformations in case of multiple root components.
  • Fixed an error in tiglWingComponentSegmentGetPoint in case of multiple intersections of the eta plane with the wing.
    This was the case for e.g. box wings. (issue #176).
  • Fixed bug tiglWingGetSpan in wing span computation when no wing symmetry is given (e.g. for a VTP) (issue #185 and #195).
  • Fixed another bug in tiglWingGetSpan when the symmetry plane was the Y-Z plane (issue #174).
  • Fixed incorrect result in tiglWingGetSegmentEtaXsi near wing sections, returning the wrong section (issue#187).
  • Fixed an issue in tiglWingGetSegmentEtaXsi in case the airfoil is completely above the chord surface.
  • Fixed point projection on the geometry for large scale data (eg a factor of 1000) by making the convergence criterium size dependent (issue #203).
• TiGLViewer:
  • Visualization of rotorcraft and rotorcraft specific menus.
  • Visualization of generic aircraft systems.
  • Added wingGetSpan function to TiGLViewer scripting.
  • Added script function wingComponentSegmentGetPoint.
  • Fixed tiglviewer.sh script loading wrong OpenCASCADE libraries.
• Language bindings:
  • Started experimental python bindings for the internal API.
    This allows a direct manipulation of the geometry objects
    from python together with the OpenCASCADE python bindings (pythonocc).
  • The source code of the matlab bindings is now shipped on all systems. In addition,
    we distribute a Makefile which can be used to compile the Matlab bindings when needed.
  • Added function tiglWingComponentSegmentComputeEtaIntersection to java bindings.
