font-family:Arial'>I used VTK some time ago (so I am not new to it) and now I
need to work with it again. I need to ask a question which may be a bit obvious
to more experienced users. Anyway… basically, I need to compute the
equation of a line, defined as the intersection of two planes. I have the plane
equations available, so I want to know if there is a straightforward way to
compute this using the vtk classes. I looked into the vtkImplicitBoolean class,
but it is not clear if it allows to extract the line equation if two planes are
added to it and the operation is set to intersection.<o:p></o:p></span></font></p>
