To show a developing process or to demonstrate changes, an in-place animation can be more convenient than a series of images.
As an example application, we will draw a recursively-defined fractal curve, the Koch curve. An animation will present the stages of the curve, which become more complex with higher numbers of recursions.
The animate package provides a simple way to generate an animation. Try this with the Koch curve, to show growing complexity by performing the following steps:
Start with any document class. Here, we choose the
standaloneclass, which we already mentioned earlier. Here, the paper tightly fits the animation:\documentclass[border=10pt]{standalone}Load the
animatepackage:\usepackage{animate}Load the TikZ package. Furthermore, load the
lindenmayersystemslibrary for producing fractals, and theshadingslibrary to fill with a shading:\usepackage{tikz} \usetikzlibrary{lindenmayersystems,shadings}
