Panda3D is a 3D engine: a library of subroutines for 3D rendering and game development. The library is C++ with a set of Python bindings. Game development with Panda3D usually consists of writing a Python or C++ program that controls the Panda3D library.
Panda3D is unusual in that its design emphasis is on supporting a short learning curve and rapid development. It is ideal whenever deadlines are tight and turnaround time is of the essence.
