class eradiate.scenes.shapes.ShapeNode(id='shape', bsdf=None, to_world=None)[source]#

Bases: Shape, NodeSceneElement, ABC

Interface for shapes which can be represented as Mitsuba scene dictionary nodes.


Traverse this scene element and collect kernel dictionary template and parameter update map contributions.


callback (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 bbox#

Shape bounding box. Default implementation raises a NotImplementedError.



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#

dict[str, UpdateParameter] or None – A dictionary mapping parameter paths, consisting of dot-separated strings, to a corresponding update protocol.

abstract 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 mitsuba.load_dict() function, or InitParameter instances which must be rendered.
