Hi,

 

following code segment is from Arr_vertical_decomposition_visitor.h (CGAL-3.3.1):

 

bool after_handle_event(Event* event, SL_iterator above, bool /* above_on_event */)

{

if (! event->is_finite())

{

// We only need to consider events with a finite x-cooridinates.

if (event->infinity_at_x() != NO_BOUNDARY)

return (true);

Boundary_type y_inf = event->infinity_at_y();

if (y_inf == PLUS_INFINITY)

{

// Update the fictitious top halfedge.

m_top_he = m_top_he->twin()->next()->twin();

}

else

{

CGAL_assertion (y_inf == PLUS_INFINITY);

// Update the fictitious bottom halfedge.

m_bottom_he = m_bottom_he->prev();

}

return (true);

}

 

The CGAL_assertion should check for y_inf == MINUS_INFINITY, shouldn´t it?

 

Kind regards,
