[vtkusers] IntersectWithLine Arguments

[David Gobbi]

Hi Will,

This question comes up a lot.  This method cannot be used from Tcl,
because pass-by-reference and non-const array parameters are not
supported by the Tcl wrappers.  I don't think that VTK has an
equivalent method that is available from Tcl.
