I recently had a question about displaying iv files on to slicer. This was solved with the amazing help of @lassoan (source). He made an iv file displayer in the sandbox extension which works perfectly. I currently want to learn how to allow the user to transform the bones in the x, y, or z axis. I was wondering what the best way to go about this would be. I was going to create a new module to help me accomplish this but am struggling as to how I would access the polydata that is in the sandbox extension that displays the iv files right now.
PS: This might seem like a basic question but I am incredibly new to slicer and don’t understand its architecture that well so any advice/materials that could help me understand the big-level architecture would be much appreciated too
Thank you in advance.
