Qt3D/QML Geometry Bounding Box



  • Hello. How do I get the bounding box of a Geometry? I need to measure the extents so I can position it properly. Specifically, I'm trying to center an ExtrudedTextMesh, but I will need to measure other geometries. Thanks.



  • Hi! AFAIK there's no public interface for that. But the object picker does just that, it visits the geometry nodes of a scene and computes the bounding spheres for the single triangles and whole meshes. Maybe you want to have a look at the sources and see what you can reuse.



  • @Wieland I was afraid of that. Seems like a glaring omission. Oh well, I needed to download the sources anyway to peek at Scene3D. Thanks.
