text: Title: Can nerfstudio's implementation of gaussian splatting pass gradients to the camera pose, thus optimizing the camera pose like nerfacto does?
  Body: 
  Very great implementation！
  
  I noticed that 3dgs is supported by nerfstudio, so wanted to know if the posture optimization method provided by nerfstudio is also supported on 3dgs？
  
  I try to train 3dgs like this:
  
        CUDA_VISIBLE_DEVICES=1 ns-train gaussian-splatting --data colmap_data --pipeline.model.camera-optimizer.mode SE3
  
  Although there is a configuration for camera posture optimization in the configuration file, I don't know how to observe such an impact from the results. For example, can I observe the camera's position movement trajectory in the viewer?
