vector of points in all_intersected_entities

Asked by Brent Fillery

An option to query mesh object intersections using python is mesh.all_intersected_entities(entities, ids_result); where mesh=dolfin.cpp.Mesh()

I can successfully return a result if a sinlge point object (dolfin.cpp.Point(x,y,x)) is supplied as argument entities. However i am having encountering errors when attempting to supply a list of points.

Documentation for this command indicates that the argument entities can be a list of point or a vector of point objects.

How does one correctly construct this vector of point objects?

For example, a simple list of point objects [p1, p2, ..., p3] is not a suitable for argument entities.

Thank you

Brent

Unfortunaltely is this feature not yet supported in the Python interface.
Neither are other "list of" arguments.
