Panda3D: An open-source framework for 3D rendering and games

Panda3D is a scene graph engine that allows you to create and manipulate 3D objects in a virtual world. You can insert 3D models, textures, animations, sounds, lights, cameras, and more into your scene, and control them with either Python or C++ code. Panda3D handles the low-level details of rendering, input, audio, collision detection, physics, networking, and more, so you can focus on your game logic and creativity.

The features and benefits of Panda3D

Here are some of the reasons why you might want to use Panda3D for your next project:

Cross-platform support

Panda3D supports Windows, Linux, macOS, Android, and iOS platforms. You can develop your application on any of these platforms, and deploy it on all of them with minimal effort. Panda3D also supports various graphics APIs, such as OpenGL, DirectX, Vulkan, Metal, and WebGL.

Powerful and flexible API

Panda3D exposes the full power of the graphics card through an easy-to-use API. You can access advanced features such as shaders, instancing, tessellation, compute shaders, ray tracing, and more. You can also customize the rendering pipeline to suit your needs. Panda3D combines the speed of C++ with the ease of use of Python to give you a fast rate of development without sacrificing on performance.

Free and permissive license

Panda3D is completely free to use with no royalties, license payments, registration or costs of any sorteven for commercial use. The source code is available for anyone to study and to modify under the terms of the permissive BSD license. You can also contribute to the development of Panda3D by submitting bug reports, feature requests, patches, or documentation.

How to get started with Panda3D

Now that you have learned what Panda3D is and what it can do for you, let's see how you can get started with it.

Installing the SDK

The easiest way to install Panda3D is to use the SDK installer that is provided on the official website. The SDK installer contains everything you need to start developing with Panda3D: the library binaries, the Python modules, the tools, and the documentation.

Downloading the installer

To download the installer, go to [the download page](^1^) and choose the version that matches your platform and Python version. For example, if you are using Windows 10 and Python 3.9, you would download panda3d-1.10.13-x64-py39.exe.

Running the installer

To run the installer, double-click on the downloaded file and follow the instructions on the screen. You can choose the installation directory, the components to install, and the Python version to use. The installer will also create shortcuts for the Panda3D tools and documentation on your desktop and start menu.

Verifying the installation

To verify that the installation was successful, open a command prompt or a terminal and type the following command:

python -m panda3d

This should launch a Panda3D window with a rotating panda head. If you see this, congratulations! You have successfully installed Panda3D on your system.

Exploring the documentation and examples

Before you start creating your own Panda3D programs, you might want to familiarize yourself with the documentation and examples that are provided with the SDK.

Browsing the manual

The manual is a comprehensive guide that covers everything from the basics of Panda3D to the advanced topics and techniques. You can access the manual from the shortcut on your desktop or start menu, or from [the online version]. The manual is divided into chapters that cover different aspects of Panda3D, such as rendering, animation, input, audio, physics, networking, and more. You can also use the search function to find specific topics or keywords.

Joining the discussion

If you have any questions, feedback, or suggestions about Panda3D, you can join the discussion on [the official forum] or [the Discord server]. There you can interact with other Panda3D users and developers, ask for help, share your projects, and learn from others. You can also report any bugs or issues on [the GitHub repository].

Running the sample programs

The SDK also comes with a collection of sample programs that demonstrate various features and capabilities of Panda3D. You can run these programs from the shortcut on your desktop or start menu, or from the samples directory in your installation folder. Each sample program has a README file that explains what it does and how it works. You can also view and modify the source code of these programs to learn how they are implemented.

Creating your first Panda3D program

Now that you have installed Panda3D and explored its documentation and examples, you are ready to create your first Panda3D program. In this section, we will guide you through creating a simple program that loads a 3D model of a panda and displays it on the screen.

Importing the Panda3D modules

The first step is to import the Panda3D modules that we will need for our program. We will use the direct.showbase.ShowBase module to create a window and a scene graph, and the panda3d.core module to access some core classes and functions. To import these modules, add the following lines at the top of your Python file:

from direct.showbase.ShowBase import ShowBase from panda3d.core import *

Loading a 3D model

The next step is to load a 3D model of a panda into our scene. Panda3D supports various 3D file formats, such as .bam, .egg, .gltf, .obj, .x, .fbx, and more. For this example, we will use a .bam file that is included in the SDK. To load this file, we need to create an instance of the ShowBase class, which will create a window and a scene graph for us. Then we need to call the loader.loadModel method, which will return a NodePath object that represents our model in the scene graph. Finally, we need to call the reparentTo method on our model to attach it to the root node of our scene graph. To do this, add the following lines after importing the modules: base = ShowBase() model = loader.loadModel("models/panda-model") model.reparentTo(render)

Adding a camera and a light

The next step is to add a camera and a light to our scene, so we can see our model better. Panda3D automatically creates a default camera and a default light for us, but we can adjust their positions and orientations as we like. To do this, we need to access the camera and light attributes of our ShowBase instance, which are also NodePath objects. Then we need to call the setPos and setHpr methods on them, which will set their position and heading, pitch, and roll angles. To do this, add the following lines after loading the model: camera.setPos(0, -30, 6) camera.setHpr(0, -5, 0) light = base.directionalLight light.setPos(0, 0, 10) light.setHpr(0, -60, 0)

Running the main loop

The final step is to run the main loop of our program, which will update the scene and handle the events. To do this, we need to call the run method of our ShowBase instance. This method will keep running until we close the window or press Ctrl-C. To do this, add the following line at the end of your Python file:

base.run()

Congratulations! You have just created your first Panda3D program. If you run this program, you should see a window with a 3D panda model that you can rotate with your mouse. You can also press Esc to exit the program.
