Rotate novel view

Hi, thanks for sharing the good work.
it's difficult to rotate the view in the viewer, blur due to too much rotation.
I wonder if there is a view_matrix that can rotate 360 degrees in a certain position, Or is there another way to customize the view's trajectory? (It's not the same trajectory as training)

Hi @JOP-Lee, there are a few parameters in the viewer.py script that might be of some help:

  • --origin-view: sets the world origin to the scene center
  • --init_view: one can specify the name of the training camera based on which the viewer will initialize, or provide a filename to the extrinsics parameters of the new camera to initialize from

You can also use the generate_dataset.py script and specify your novel trajectory in the --view-matrix parameter. The script will save a set of rendered pictures along the specified trajectory.
