A couple of things:

1) you should use smart pointers:
vtkSmartPointer<vtkSTLWriter> writer = vtkSmartPointer<vtkSTLWriter>::New();
instead of
vtkSTLWriter writer = vtkSTLWriter::NEW();  // I'm not sure NEW()
works here? Shouldn't it be New()?

2) what type is triangle2?

3) I'm assuming you called writer->Write() ?

I'd suggest making the smallest possible example of using vtkSTLWriter
(we need an example of this anyway :) ) and seeing if you get the same
behavior. Do something very controlled like add a few points and
vertices or a triangle or something and see what happens.

Thanks,
