A group with partial order.
Ordered groups with a common parent are rendered in ascending order of their order field. This is a useful way to render multiple layers of a scene within a single batch.
Constructor:
Create an ordered group.
Parameters: |

Methods:
set_state() Apply the OpenGL state change. set_state_recursive() Set this group and its ancestry. unset_state() Repeal the OpenGL state change. unset_state_recursive() Unset this group and its ancestry.
Methods
- OrderedGroup.set_state()
Apply the OpenGL state change.
The default implementation does nothing.
- OrderedGroup.set_state_recursive()
Set this group and its ancestry.
Call this method if you are using a group in isolation: the parent groups will be called in top-down order, with this class’s set being called last.
- OrderedGroup.unset_state()
Repeal the OpenGL state change.
The default implementation does nothing.
- OrderedGroup.unset_state_recursive()
Unset this group and its ancestry.
The inverse of set_state_recursive.
