Don't mind the mess!
We're currently in the process of migrating the Panda3D Manual to a new service. This is a temporary layout in the meantime.
Panda3D's camera is considered a PandaNode. It can therefore be manipulated as any other node.
The actual camera is defined in ShowBase as a NodePath named
base.cam. There is also a plain node above the camera, which is a NodePath called
base.camera. Generally you want to control the
base.camera NodePath with your code.
