eradiate.kernel.SearchSceneParameter¶

class eradiate.kernel.SearchSceneParameter(node_type, node_id, parameter_relpath)[source]¶

Bases: object

This class defines a scene parameter search protocol applied during the Mitsuba scene tree traversal.

Instances are callables which take, as argument, the current node during a Mitsuba scene tree traversal and, optionally, its path in the Mitsuba scene tree. If the lookup succeeds, the full parameter path is returned.

Parameters:

node_type (type) – Type of the node which will be looked up.
node_id (str) – ID of the node which will be looked up.
parameter_relpath (str) – Parameter path relative to its parent object.

Fields:

node_type (type) – Type of the node which will be looked up.
node_id (str) – ID of the node which will be looked up.
parameter_relpath (str) – Parameter path relative to its parent object.
