DLR-SC/tigl v3.0.0rc1

TiGL 3.0.0 RC1

on GitHub

General Changes:

• CPACS 3 compatibility, including the new component-segment coordinate-system math.
  Note: As CPACS 3 is not officially released yet, the development version of CPACS as of December 18th, 2017 is used.
  Note: The wing structure is not yet adapted to CPACS 3 but uses the 2.3 definition.
• Guide curve support for wings and fuselages for high-fidelity surface modeling according to the CPACS 3 defintion.
• Automated creation of CPACS reading and writing routines. This allows much
  better vality checks of the CPACS document.
• Improved speed of ::tiglFuselageGetPoint function. Also, the paramter xsi is now interpreted as the relative
  curve parameter instead of the relative circumference.
• The TIGL library was renamed to tigl3. The TIGLViewer was renamed to tiglviewer-3.
• The windows builds are now using the Visual C++ 2015 Toolchain.

New API functions:

• tiglWingComponentSegmentPointGetEtaXsi computes the eta/xsi coordinates of a point on the component segment.
• tiglIntersectWithPlaneSegment computes the intersection of a CPACS shape (e.g. wing) with a plane of finite size.
• tiglGetCurveIntersection to compute the intersection of two curves.
• tiglGetCurveIntersectionPoint to query the intersection point(s) computed by tiglGetCurveIntersection.
• tiglGetCurveIntersectionCount returns the number of intersection points computed by tiglGetCurveIntersection.
• tiglGetCurveParameter projects a point onto a curve and returns the curve parameter of the point.
• tiglFuselageGetSectionCenter computes the center of a fuselage section defined by its eta coordinate.
• tiglFuselageGetCrossSectionArea computes the area of a fuselage section.
• tiglFuselageGetCenterLineLength computes the length of the centerline of the fuselage.
• tiglCheckPointInside checks, whether a point lies inside some object (defined by its uid).
• tiglExportFuselageBREPbyUID and tiglExportWingBREPByUID

Changed API:

• Removed deprectated intersection functions. These include
  • tiglComponentIntersectionLineCount
  • tiglComponentIntersectionPoint
  • tiglComponentIntersectionPoints

Fixes:

• TiGL Viewer: Fixed missing fonts on macOS

Language bindings:

• Python: the tiglwrapper.py module was renamed to tigl3wrapper.py. The Tigl object is renamed to Tigl3.
• Java: the tigl package moved from de.dlr.sc.tigl to de.dlr.sc.tigl3

TiGL Viewer:

• New design
• Custom OpenGL shaders. If problems with the 3D rendering occur, please file a bug.
• Display of reflection lines to inspect surface quality.
• Display of textured surfaces.
• Angle of perspective can be adjusted using the scripting API with setCameraPosition and setLookAtPosition.
  This allows e.g. to create videos of the geometry.
• Option to display face names.
• Number of U and V iso-lines can be adjusted independently.
