from panda3d.core import DataNode
The fundamental type of node for the data graph. The DataNode class is itself primarily intended as an abstract class; it defines no inputs and no outputs. Most kinds of data nodes will derive from this to specify the inputs and outputs in the constructor.
DataNode does not attempt to cycle its data with a PipelineCycler. The data graph is intended to be used only within a single thread.
