VisibilityQuery
Queries a scene location to see if it is visible, taking
into account the scene:visible attribute on it and all of
its ancestors.
Note
If an ancestor is invisible, then all its descendants
are too, no matter the value of their own scene:visible
attribute. In other words, invisible locations prune entire
subhierarchies from the scene.
user
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
scene
The scene to query the visibility from.
location
The location within to query the visibility for.
Note
If the location does not exist then the query will not be performed and all outputs will be set to their default values.
visible
Outputs True if the location is visible, and False otherwise.
invisibleAncestors
Outputs the list of all ancestors of location which have a
scene:visible attribute set to False. This is the minimal
list of locations that would need to be made visible in
order for the location to be seen.
Note
Also includes the location itself if it has scene:visible
set to False.
Tip
To make the location visible, use DeleteAttributes to delete
the scene:visible attribute, filtering via a PathFilter driven
by invisibleAncestors.
