void GreatCircleArc::LineSegment::doGL (  double  width, VisualizationState *  state, LineSegment *  preceding = NULL, LineSegment *  proceeding = NULL )  const

Draw a meshed line. Parameters: width  the width of the line state  The visualization state needed to obtain final 3D coordinates and the scale for the visualization preceding  the line segment before this line segment, needed to calculate the right begining slope proceeding  the line segment after this line segment, needed to calculate the right ending slope Definition at line 256 of file GreatCircles.cpp. References hugin_utils::FDiff2D, MeshManager::GetCoord3D(), VisualizationState::GetMeshManager(), VisualizationState::GetScale(), vertices, MeshManager::MeshInfo::Coord3D::x, hugin_utils::TDiff2D< T >::x, MeshManager::MeshInfo::Coord3D::y, hugin_utils::TDiff2D< T >::y, and MeshManager::MeshInfo::Coord3D::z.
