- class eradiate.scenes.surface.Surface(id='surface')[source]#
An abstract base class defining common facilities for all surfaces.
All scene elements deriving from this interface are composite and cannot be turned into a kernel scene instance on their own: they must be owned by a container which take care of expanding them.
str, optional, default:
"surface") – Identifier of the current scene element.
This class is to be used as a mixin.
Traverse this scene element and collect kernel dictionary template and parameter update map contributions.
SceneTraversal) – Callback data structure storing the collected data.
Enforce internal state consistency. This method should be called when fields are modified. It is automatically called as a post-init step.
- property objects#
Map of child objects associated with this scene element.
dict– A dictionary mapping object names to a corresponding object to be inserted in the Eradiate scene graph.
- property params#
None– A dictionary mapping parameter paths, consisting of dot-separated strings, to a corresponding update protocol.
- property template#
Kernel dictionary template contents associated with this scene element.
dict– A flat dictionary mapping dot-separated strings describing the path of an item in the nested scene dictionary to values. Values may be objects which can be directly used by the
InitParameterinstances which must be rendered.
