Panda3D

Panda3D is a game engine, a framework for 3D rendering and game development for Python and C++ programs. Panda3D is open-source and free for any purpose, including commercial ventures, thanks to its liberal license. To learn more about Panda3D's capabilities, visit the gallery and the feature list. To learn how to use Panda3D, check the documentation resources. If you get stuck, ask for help from our active community.

Installing Panda3D

The latest Panda3D SDK can be downloaded from this page. If you are familiar with installing Python packages, you can use the following command:

pip install panda3d

The easiest way to install the latest development build of Panda3D into an existing Python installation is using the following command:

pip install --pre --extra-index-url https://archive.panda3d.org/ panda3d

If this command fails, please make sure your version of pip is up-to-date.

If you prefer to install the full SDK with all tools, the latest development builds can be obtained from this page.

These are automatically kept up-to-date with the latest GitHub version of Panda.

Building Panda3D

Windows

You can build Panda3D with the Microsoft Visual C++ 2015, 2017 or 2019 compiler, which can be downloaded for free from the Visual Studio site. You will also need to install the Windows 10 SDK, and if you intend to target Windows Vista, you will also need the Windows 8.1 SDK.

You will also need to have the third-party dependency libraries available for the build scripts to use. These are available from one of these two URLs, depending on whether you are on a 32-bit or 64-bit system, or you can click here for instructions on building them from source.

After acquiring these dependencies, you can build Panda3D from the command prompt using the following command. Change the --msvc-version option based on your version of Visual C++; 2019 is 14.2, 2017 is 14.1, and 2015 is 14. Remove the --windows-sdk=10 option if you need to support Windows Vista, which requires the Windows 8.1 SDK.

makepanda\makepanda.bat --everything --installer --msvc-version=14.2 --windows-sdk=10 --no-eigen --threads=2

When the build succeeds, it will produce an .exe file that you can use to install Panda3D on your system.

Note: you may choose to remove --no-eigen and build with Eigen support in order to improve runtime performance. However, this will cause the build to take hours to complete, as Eigen is a heavily template-based library, and the the MSVC compiler does not perform well under these circumstances.

Linux

Building Panda3D on Linux is easy. All you need is to invoke the makepanda script using the version of Python that you want Panda3D to be built against.

Run makepanda.py with the --help option to see which options are available. Usually, you will want to specify the --everything option (which builds with support for all features for which it detects the prerequisite dependencies) and the --installer option (which produces an installable .deb or .rpm file for you to install, depending on your distribution).

The following command illustrates how to build Panda3D with some common options:

python3 makepanda/makepanda.py --everything --installer --no-egl --no-gles --no-gles2 --no-opencv

You will probably see some warnings saying that it's unable to find several dependency packages. You should determine which ones you want to include in your build and install the respective development packages. You may visit this manual page for an overview of the various dependencies.

If you are on Ubuntu, this command should cover the most frequently used third-party packages:

sudo apt-get install build-essential pkg-config fakeroot python3-dev libpng-dev libjpeg-dev libtiff-dev zlib1g-dev libssl-dev libx11-dev libgl1-mesa-dev libxrandr-dev libxxf86dga-dev libxcursor-dev bison flex libfreetype6-dev libvorbis-dev libeigen3-dev libopenal-dev libode-dev libbullet-dev nvidia-cg-toolkit libgtk2.0-dev libassimp-dev libopenexr-dev

Once Panda3D has built, you can either install the .deb or .rpm package that is produced, depending on which Linux distribution you are using. For example, to install the package on Debian or Ubuntu, use this:

sudo dpkg -i panda3d*.deb

If you are not using a Linux distribution that supports .deb or .rpm packages, you may have to use the installpanda.py script instead, which will directly copy the files into the appropriate locations on your computer. You may have to run the ldconfig tool in order to update your library cache after installing Panda3D.

Alternatively, you can add the --wheel option, which will produce a .whl file that can be installed into a Python installation using pip.

macOS

On macOS, you will need to download a set of precompiled thirdparty packages in order to compile Panda3D, which can be acquired from here.

After placing the thirdparty directory inside the panda3d source directory, you may build Panda3D using a command like the following:

python makepanda/makepanda.py --everything --installer

You may target a specific minimum macOS version using the --osxtarget flag followed by the release number, eg. 10.9 or 10.14.

If the build was successful, makepanda will have generated a .dmg file in the source directory containing the installer. Simply open it and run the package file in order to install the SDK onto your system.

FreeBSD

Building on FreeBSD is very similar to building on Linux. You will need to install the requisite packages using the system package manager. To install the recommended set of dependencies, you can use this command:

pkg install pkgconf bison png jpeg-turbo tiff freetype2 harfbuzz eigen squish openal opusfile libvorbis libX11 mesa-libs ode bullet assimp openexr

You will also need to choose which version of Python you want to use. Install the appropriate package for it (such as python37 or python38) and run the makepanda script with your chosen Python version:

python3.7 makepanda/makepanda.py --everything --installer --no-egl --no-gles --no-gles2

If successful, this will produce a .pkg file in the root of the source directory which you can install using pkg install.

Android

Note: building on Android is very experimental and not guaranteed to work.

You can experimentally build the Android Python runner via the termux shell. You will need to install Termux and Termux API from the Play Store. Many of the dependencies can be installed by running the following command in the Termux shell:

pkg install python ndk-sysroot clang bison freetype harfbuzz libpng eigen openal-soft opusfile libvorbis assimp libopus ecj dx patchelf aapt apksigner libcrypt openssl pkg-config

Then, you can build the .apk using this command:

python makepanda/makepanda.py --everything --target android-21 --no-tiff --installer

You can install the generated panda3d.apk by browsing to the panda3d folder using a file manager. You may need to copy it to /sdcard to be able to access it from other apps.

To launch a Python program from Termux, you can use the run_python.sh script inside the panda/src/android directory. It will launch Python in a separate activity, load it with the Python script you passed as argument, and use a socket for returning the command-line output to the Termux shell. Do note that this requires the Python application to reside on the SD card and that Termux needs to be set up with access to the SD card (using the termux-setup-storage command).

Running Tests

Install PyTest and run the pytest command. If you have not installed Panda3D, you will need to configure your environment by pointing the PYTHONPATH variable at the built directory. On Linux, you will also need to point the LD_LIBRARY_PATH variable at the built/lib directory.

As a convenience, you can alternatively pass the --tests option to makepanda.

Reporting Issues

If you encounter any bugs when using Panda3D, please report them in the bug tracker. This is hosted at:

https://github.com/panda3d/panda3d/issues

Make sure to first use the search function to see if the bug has already been reported. When filling out a bug report, make sure that you include as much information as possible to help the developers track down the issue, such as your version of Panda3D, operating system, architecture, and any code and models that are necessary for the developers to reproduce the issue.

If you're not sure whether you've encountered a bug, feel free to ask about it in the forums or the IRC channel first.
