movieRSA {RSA}

Create a movie of plotRSA plots, with changing surface and/or rotation

Description

Create a movie of plotRSA plots, with changing surface and/or rotation

Usage

movieRSA(
  name,
  frames,
  dur = 2000,
  fps = 30,
  width = 800,
  height = 600,
  mirror = TRUE,
  savetodisk = TRUE,
  clean = TRUE
)

Arguments

name

Name for the subfolder containing all still pictures, and for the final movie file.

frames

A list of lists: Each list contains parameters which are passed to the plotRSA function. See plotRSA for details.

dur

Duration of the movie in milliseconds

fps

Frame per second (defaults to 30)

width

Width of the final movie in pixels

height

Height of the final movie in pixels

mirror

If TRUE, the frame sequence is mirrored at the end so that the movie ends at frame 1.

savetodisk

If TRUE the files are saved to the disk. If FALSE, the movie is only shown on the screen

clean

Should the still images be deleted?

Details

frames is a list of the first, intermediate, and the final parameters of the surface. Each scalar parameter defined in frames is interpolated between steps in order to create a smooth sequence of plots. Logical and character parameters are inherited from the first frame. Plots are saved as individual still pictures in a subfolder called name and finally glued together using ffmpeg. Hence, a ffmpeg installation is needed to create the movie (the still pictures can be produced without ffmpeg).
