differt_core.geometry.SionnaScene

class SionnaScene

Bases: object

A scene as loaded from a Sionna-compatible XML file.

Only a subset of the XML file is actually used.

This scene acts as a bridge between Sionna and DiffeRT, and is essentially used to quickly load scenes from Sionna and export them as a Scene.

Warning

We are still open to better ways to parse those XML files, please reach out us if you would like to help!
