Render specific frames, panoramic views from specific poses, or uniformly sampled from camera path

[paolovic]

Hi,

as described in #2811 I added the following functionality:

• Enter a desired eye position in world coordinates, and optionally a desired target, and get in return the images of the panoramic view from that pose in parallel to the floor. Anything is adjustable: eye, target, view angle, intermediate steps

  • If you want just a single image, set the start-angle equal to the end-angle and 0 intermediate steps
  • Example usage: ns-render pose-view --output-format images --load-config outputs/room1/splatfacto/2024-06-07_104843/config.yml --eye "0 0 -2" --load-dataparser-transforms outputs/room1/splatfacto/2024-06-07_104843/dataparser_transforms.json

• Sample uniformly from the camera path and get the views from the corresponding view points

  • Example usage: ns-render pose-view --output-format images --load-config outputs/room1/splatfacto/2024-06-07_104843/config.yml --viewpoints 3

instead of (yet again) wrapping the already-convoluted _render_trajectory_video(), perhaps this could be a script and/or module that outputs a camera_path json file, then the user can just use the existing render.py with that input. and then there's also a camera path fixture that can be (1) unit tested and (2) debugged outside the render loop

Hi,
thanks for the feedback, and feedback addressed.
