Operating system: Ubuntu 18.04
Slicer version: 4.8.1
Expected behavior: Move an .stl polydata around in the 3d view
Hi, I want to create an overlay of a needle both on the 3d view and the 2d slices. I have tried to use fiducials by sending a pointcloud over OpenIGTLink but when the number of fiducials goes up the app becomes significantly laggy. I figured that by using a polydata overlay, I can both see the shape in the 3d view and see an intersection with actual dicom slices in the 2d slices viewer.
The problem I am facing is that I want to move this polydata thing around (changing its position and orientation), preferrably with transforms as I can easily send transforms over from ROS using OpenIGTLink.
Any help will be very much appreciated!
