EggData
from panda3d.egg import EggData
- class EggData
Bases:
EggGroupNodeThis is the primary interface into all the egg data, and the root of the egg file structure. An EggData structure corresponds exactly with an egg file on the disk.
The EggData class inherits from EggGroupNode its collection of children, which are accessed by using the EggData itself as an STL container with begin() and end() calls. The children of the EggData class are the toplevel nodes in the egg file.

there is no such filename, you may set it to the empty string.
