Animations On PDF Using Lua and LaTeX
1 like2,042 views
The document proposes developing an interface for animating algorithms and data structures in PDF documents using TEX. It will use packages like TikZ and animate.sty for drawing diagrams and creating animations in LaTeX. The interface will have high-level and low-level APIs for end users and expert users. It provides sample code for using TikZ and animate.sty to draw diagrams and create animations programmatically in LaTeX.
