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.

Building Panda3D

Windows

We currently build using the Microsoft Visual C++ 2010 compiler. You do not need Microsoft Visual Studio to build Panda3D, though - the relevant compilers are included as part of the Windows 7.1 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: https://panda3d.org/download/panda3d-1.9.2/panda3d-1.9.2-tools-win32.zip https://panda3d.org/download/panda3d-1.9.2/panda3d-1.9.2-tools-win64.zip

After acquiring these dependencies, you may simply build Panda3D from the command prompt using the following command:

makepanda\makepanda.bat --everything --installer --no-eigen

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:

python2.7 makepanda/makepanda.py --everything --installer --no-egl --no-gles --no-gles2

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 python-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

Once Panda3D has built, you can either install the .deb or .rpm package that it 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.

Mac OS X

On Mac OS X, 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

In order to make a universal build, pass the --universal flag. You may also target a specific minimum Mac OS X version using the --osxtarget flag followed by the release number, eg. 10.6 or 10.7.

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.

Reporting Issues

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

https://bugs.launchpad-/panda3d

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.
