<div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Hello. I'm trying to do slicing of a complex model polygonal (read from an STL file) with vtkCutter and I'm struggling to understand whether the resulting polygons are "inside" or "outside". I realized that if I knew the normal direction of the triangles cut by the vtkCutter, I could orient the line segments of the cutting polygon such that "inside" is e.g. always on the left side. But I couldn't find whether vtk retains a connection between the cut polygon line segments and the corresponding 3D triangles that it cut? <br>
