Render video from trajectory — render_trajectory

The function repeatedly calls plot_position function to generate preview of the trajectory motion. Extra time is added before and after the motion sequence (2 seconds each).

Usage

render_trajectory_video(
  filename,
  trajectory,
  settings = default_settings(),
  targets = NULL,
  outdir = getwd(),
  ...
)

Arguments

filename: the file name of output video (e.g. "trajectory.mp4")
trajectory: tibble with trajectory data
settings: list with basic properties
targets: Which objects should be treated as targets
outdir: output directory where the video is saved
...: Parameters passed to `plot_position`

Value

No return value

Examples

if (FALSE) {
# this example can take 30 seconds to run
# set ffmpeg in necessary
# ani.options(ffmpeg = "/PATH/TO/ffmpeg/ffmpeg")
render_trajectory_video("trajectory.mp4", trajectory8c,
  new_settings(show_labels = TRUE),
  targets = 1:4
)
