Panda3D 使用的模型文件格式叫做 egg 。您需要使用建模软件（比如 3D Studio Max、Blender、Maya）之中的一款，配合相应的导出插件或是文件格式转换工具。后面将会详细介绍。Panda3D 也支持能够快速载入的 bam 格式的二进制文件。

主旨：

"Panda3D uses a custom file format for its models, called egg. To create an egg file, you will need to use a modeling program (like 3D Studio Max, Blender or Maya) combined with either an export plugin or a file format converter. You can read more about this process in the following sections. Panda3D also provides a binary file format bam, which is quicker to load."
