The title says it all. Take this example : https://lorensen.github.io/VTKExamples/site/Cxx/GeometricObjects/PolyLine/ and insert this line of code after line 68
Build & run the example, you will see that there is a gap between lines.
When using solely Qt to draw the same thing, such a gap doesn’t exist (there’s 3 type of pen joins : Round, Bevel and Mitter according to this example https://doc.qt.io/qt-5/qtwidgets-painting-basicdrawing-example.html).
Does VTK offer something to set the join type between lines ?
