arrow to show orientation

Fabio Napodano's picture


I need to show the TopAbs_Orientation of a Geom_BSplineSurface-derived TopoDS_Shape by the mean of Arrow objects drawed on the middle of each edge.

Is there an easy way to achieve such a result?

I've searched through the forum and found how to represent a vector by overriding the Draw() method, but this can be quite difficult to do if I need to put the vector on the middle of a curved edge.

Any easier suggestions?

Thanks in advance.
