TextureStagePool
from panda3d.core import TextureStagePool
- class TextureStagePool
Bases:
DTOOL_SUPER_BASEThe TextureStagePool (there is only one in the universe) serves to unify different pointers to the same TextureStage, mainly to help developers use a common pointer to access things that are loaded from different model files.
It runs in one of three different modes, according to set_mode(). See that method for more information.

Each call to get_stage() passing an equivalent TextureStage pointer will
return the same shared pointer.
If you modify the shared pointer, it will automatically disassociate it
from the pool.
Also, the return value may be a different pointer than that passed in, or
it may be the same pointer. In either case, the passed in pointer has now
been sacrificed to the greater good and should not be used again (like any
other PointerTo, it will be freed when the last reference count is
removed).
