Detailed Description

template<int dim, int spacedim>
class OpenCASCADE::ArclengthProjectionLineManifold< dim, spacedim >

A Manifold object based on OpenCASCADE TopoDS_Shape objects which have topological dimension equal to one (TopoDS_Edge or TopoDS_Wire) where new points are located at the arclength average of the surrounding points. If the given TopoDS_Shape can be casted to a periodic (closed) curve, then this information is used internally to set the periodicity of the base ChartManifold class.

This class can only work on TopoDS_Edge or TopoDS_Wire objects, and it only makes sense when spacedim is three. If you use an object of topological dimension different from one, an exception is throw.

In debug mode there is an additional sanity check to make sure that the surrounding points actually live on the Manifold, i.e., calling OpenCASCADE::closest_point() on those points leaves them untouched. If this is not the case, an ExcPointNotOnManifold is thrown.
