Hi,

I’m using VTK via the Java wrapper to display various objects. When I add an object, I have to call ResetCamera() to ensure that my new object is visible. I’d like to handle this using bounding boxes so that I only reset the camera when necessary. But the vtkBoundingBox class is not visible in the Java 9.5 wrapper (it is included in the vtk.jar, but “not visible”). I assume I’m missing something. I can’t figure out what. Do I have to do all the bounding boxes arithmetic myself? That makes no sense to me, and I haven’t made any progress by reading the documentation. Any help would be greatly appreciated.

Best regards

jMax

The vtkRenderer has a method `ComputeVisiblePropBounds()` that will compute the bounds without resetting the camera.

There are no plans to make vtkBoundingBox available through Java, as far as I know.
