Release v2.3.9.192

Meshes:

• Optionally return left mesh from trimWithPlane(…)
• Support fully degenerate triangles in Delaunay check
• Fix raytracing on GPU, output intersection point
• SubdivideSettings::projectOnOriginalMesh and RemeshSettings::projectOnOriginalMesh
• Compute connected components of undirected edges
• MeshTopology::flipOrientation( const UndirectedEdgeBitSet * fullComponents )

Polylines:

• Add Polyline::edgePoint(EdgePoint) and toEdgePoint
• Section polylines

Point Clouds:

• Triangulation: use the given number of nearest neighbors instead of a fixed radius
• Local Triangulations: quality improvements and performance optimizations, better triangulation of regular grids
• Auto-orient local triangulations without point normal
• autoOrientLocalTriangulations(…) returns repeated triangles
• Implement makeOrientedNormals(…) via autoOrientLocalTriangulations(…)
• findBoundaryPoints(…) moved in TriangulationHelpers and implemented via local triangulation
• Add functions to find (e.g. large) point cloud components
• Add trimWithPlane(…) for point clouds
• findAvgPointsRadius(…) now computes actually average radius
• Improve points sampling, more output options
• pointsToDistanceVolume(…) for signed distance field computation near points with normal, CUDA version of the function
• pointsFusion(…) to convert point cloud with normals into mesh via signed distance volume

Python interface:

• Exposed BuildSettings for building a mesh from numpy
• Expose all edgePoints

UI & Visualization:

• Add points and lines in dense box
• Support picker in point cloud mode / Add ObjectPoints and ObjectLines support in SurfacePointWidget and SurfaceContoursWidget
• Clip plane affects labels (fully show/hide by pivot point)
• detectFlatShading(…) decides by area near sharp edges
• Add clickable object names
• renderUi() objects now block onMouseDown events
• Find available custom themes
• Decrease default splash screen time
