PDF-based presentations with 3-D effects

"Before using either PDFCube or Impressive, you need to have to have support for 3-D graphics installed. PDFCube works well with OpenGL, as well as with the drivers and video cards listed on its hardware compatibility page. By contrast, Impressive is somewhat more erratic under OpenGL, with some transitions displaying slowly, especially when you have less than two gigabytes of RAM available. However, by picking and choosing effects, you can still test drive Impressive without resorting to proprietary drivers.

"Both applications are available as source code from their project sites. However, you will also need to install dependencies for PDF support, such as Poppler for PDFCube, and Xpdf Reader or Ghostscript for Impressive. Impressive also requires Perl and Python. For convenience, you may prefer to use the Debian packages for both programs, or, in the case of PDFCube, the packages available in the Fedora and Ubuntu repositories. Impressive is also available for OS X and Windows."
