Hit test as described for the geometry models works but does not work for .dae models that have been added to a scene. Stackflow seems to indicate that it is because the node does not have any geometry when the hit test is performed. Is there a method to hit test .dae models? I would like to be able to drag an object once selected. I am using Swift 3.
Have you considered have Xcode convert the .dae file to .scn files?
In the project, select the .dae file, go to the Editor Menu, select:
Convert to cenKit scene file format (.scn)
Thank you. Yes, that method works and appears that it is the simplest solution.
