====== Embed interactive visualizations in PDF files ====== 

With ''polymake'' and jReality you can even embed your visualizations as interactive applets into pdf files (from LaTeX).

  - Visualize your polytope, or any other object, with jReality. You might need to call ''%%jreality($x->VISUAL);%%'' or something similar.
  - Export the visualized object from jReality: ''File -> Export -> **U3D**''
  - In your tex-file you need to add the ''movie15'' package and then use the ''**\includemovie**'' command to include the applet: 
        <code>
        \usepackage[3D]{movie15}
        ...
      	\includemovie[
	      mimetype=model/u3d,
	      3Djscript=Encompass.js,
              autoplay
	   ]
	{ \textwidth }
	{ 0.7\textwidth }
	{object.u3d}
</code>
  - Compile the LaTeX source with **pdflatex**.
  - View the pdf file with a reasonably recent version of **[[http://get.adobe.com/reader/|Adobe Reader]]**.

==== Options for includemovie ====
  * (More or less) optional arguments:
    * ''mimetype=model/u3d'' Mandatory to tell the viewer what kind of object this is.
    * ''autoplay'' Can be set to automatically load the applet when opening the page. Otherwise you will see a white area and a small text //Click to activate//.
    * ''3Dscript'' JavaScript code to manipulate the scene (camera, lights, etc.).
  * Two arguments for the dimensions of the applet.
  * Filename.
