Panard Vision Source
Olivier Brunet announced the full source code release of Panard Vision, a feature-rich 3D engine that used to be available commercially. Here's the buzz:
"PV is a portable, high performance, full featured,
realtime 3D Engine. It supports software or hardware
rendering, depending on the platform. It is intented
to be used in everything that needs fast, high quality
3D output. Tutorials, demos, and docs are included in
the SDK. PV is not only a polygon renderer or a
Quake-like-engine, it's something versatile enough to
help you develop nearly everything which needs 3D. PV
is not tied, like other engines, to a rendering type
but is open enough to suit your needs.
It has been ported to Win32, Linux, SunOS and DOS platforms."
