The Panda3D game engine has initially been a closed-source project of Disney Interactive but was later opened to the community, allowing anyone to use the engine or contribute code. Development of Panda3D is now driven and coordinated in a joint effort by Disney Interactive and the Entertainment Technology Center of the Carnegie Mellon University. Together, they are adding new features, fixing bugs, and preparing new releases of the engine.
Panda3D is distributed under a version of the very liberal BSD open-source license, which allows anyone interested to download, view, alter, and redistribute the source code compiled binaries without ever having to pay any license fees. This applies to commercial projects too. So creating a game using Panda3D and selling it is no problem and will never require any amount of money to be paid.
Panda3D is a very powerful and feature-rich game engine that comes with a lot of features needed for creating modern video games. Using Python as a scripting language to interface with the low-level programming libraries makes it easy to quickly create games because this layer of abstraction neatly hides many of the complexities of handling assets, hardware resources, or graphics rendering, for example. This also allows simple games and prototypes to be created very quickly and keeps the code needed for getting things going to a minimum.
Panda3D is a complete game engine package. This means that it is not just a collection of game programming libraries with a nice Python interface, but also includes all the supplementary tools for previewing, converting, and exporting assets as well as packing game code and data for redistribution. Delivering such tools is a very important aspect of a game engine that helps with increasing the productivity of a development team.
The Panda3D engine is a very nice set of building blocks needed for creating entertainment software, scaling nicely to the needs of hobbyists, students, and professional game development teams. Panda3D is known to have been used in projects ranging from one-shot experimental prototypes to full-scale commercial MMORPG productions like Toontown Online or Pirates of the Caribbean Online.
Before you are able to start a new project and use all the powerful features provided by Panda3D to their fullest, though, you need to prepare your working environment and tools. By the end of this chapter, you will have a strong set of programming tools at hand, as well as the knowledge of how to configure Panda3D to your future projects' needs.
