 This function reads a camera trajectory, then defines an animation function ``move_forward`` to travel through the camera trajectory. In this animation function, both color image and depth image are captured using ``Visualizer.capture_depth_float_buffer`` and ``Visualizer.capture_screen_float_buffer`` respectively. The images are saved as png files.
