You really must simplify your problem into the very bare minimum that
is required to demonstrate it. It will usually help you find the
solution, and it will certainly make it easier for us to find the
solution. You can do this by:

- Include all necessary headers
- Remove Qt dependency
- Use a vtkSphereSource instead of loading an obj file.
- Replace "seems not working!" with the actual error.
- If it is crashing, use a debugger to tell us where.
