From the web page:

It's an attempt to develop a fast generic high quality 3D renderer, with support for the most common used rendering methods, and special FX. this engine is intended to be used in everything which needs a fast high quality rendering. PV is at the cutting edge in realtime 3D algorithms ! PV is not only a polygon renderer or a Quake-like-engine, it's something versatile enough to help you develop near everything which needs 3D, the samples includes a QuakeI&II viewer which handles collision and so on but demonstrates some other features too. PV is not tied, like other engines, to a rendering type but is open enough to suit your needs.

The strong points of Panard Vision are:

• Portability : you can recompile your Panard Vision application without rewriting a line of code. The same code will give the same results under Windows, X or every other OS PV supports.
• Abstraction : you can benefit from hardware acceleration in a transparent manner. Without changing your code you could benefit from different hardware depending on the drivers installed for your OS.
• Ease of use : the API is simple to use, and very open.
• Speed : Panard Vision really rocks ! :)
• Extensibility : the API of Panard Vision is open to YOUR code and functionnalities.
• Genericity : Panard vision is a generic 3D engine not bound to a predefined rendering method. And help you to implement yours.
