Font creation
In order to use other fonts in Papervision3D, we need to create our own custom Font3D classes. Although this may sound pretty daunting, it is not hard at all, thanks to a tool by Mathieu Badimon, the developer of Five3D.
Note
Five3D is a 3D engine written in ActionScript 3.0 that lets you create interactive vector-based 3D animations. See http://five3d.mathieu-badimon.com
In short, downloading the tool and placing in it the correct folder will create a new panel inside the Flash IDE. When the panel is opened, you can choose a font and the tool will generate an ActionScript class file that contains vector data about the font. The following screenshot shows the panel:

Go to http://code.google.com/p/five3d/downloads/list and download the latest release, which was FIVe3D_make_typography_v2.0.zip at the time of writing.
Inside the ZIP file you will find a SWF and a PDF file. The PDF contains instructions on where to place the SWF and how to create a font file. Read these instructions...
