static

Gets the maximum dimension of the given bounding box. If the given bounding box is void leaves the resulting value unchanged.

Parameters

theBox	bounding box to be processed.
theMaxDimension	maximum dimension of the given box.

static gp_XY BRepMesh_ShapeTool::FindUV ( const Standard_Integer  theIndexOfPnt3d, const gp_Pnt2d &  thePnt2d, const TopoDS_Vertex &  theVertex, const Standard_Real  theMinDistance, const Handle< BRepMesh_FaceAttribute > &  theFaceAttribute  )
