Here we will explore what is involved in creating animations (i.e., movies). Of course, an animation is nothing more than a series of individual images played back in an orderly fashion. Here, these images will have been created with GMT. A GMT movie is made with the movie module that takes care of all the book-keeping of making a movie (advancing frame counters, converting each plot to a raster image, assembling the images into a movie). The user is left to focus on the creation of a main frame script (that will have access to special variables to know which frame it is as well as user-defined data) and optional scripts that prepares files for the movie, lays down a constant background plot, and appends a constant foreground plot. The movie module explains the available options and gives a few simple examples you can cut-and-paste to run in your terminal. Below are more advanced movie examples. You can generate anything from tiny animated gif files for your PowerPoint or KeyNote presentations or a full-featured movie with thousands of frames at HD or 4k resolution.
