Panda3D Manual

Welcome to the Panda3D documentation! Panda3D is an open-source, free-to-use 3D engine made for the development of realtime 3D games, visualizations, simulations, experiments — you name it! It consists of a library of subroutines that can be used with either the Python or C++ programming language, as well as a few tools to assist with development and debugging.

There are two versions of the manual: one for Python users and one for C++ users. Use the link in the sidebar to switch between the versions. You are currently viewing the manual for Python users.

The manual is divided up into sections, which are listed below. You can at any time use the sidebar on the left side to navigate between the different sections and their contained pages.

Introduction

We recommend that beginners start out by reading through the Introduction section, which walks through the process of installing Panda3D and ends with a “Hello World” tutorial explaining how to create a very small Panda3D program, to get a sense for what using the engine looks like.

• Introduction to Panda3D
  • Installing Panda3D in Windows
  • Installing Panda3D in Linux
  • General Preparation
  • Running your Program
