• parameters (mitsuba.SceneParameters, optional, default: None) – Mitsuba scene parameter map.

• umap_template (KernelSceneParameterMap, optional, default: None) – An update map template, which can be rendered and used to update Mitsuba scene parameters depending on context information.

Fields:

• obj (mitsuba.Object) – Mitsuba object.

• parameters (mitsuba.SceneParameters) – Mitsuba scene parameter map.

• umap_template (KernelSceneParameterMap) – An update map template, which can be rendered and used to update Mitsuba scene parameters depending on context information.
