Create Scene file from Openstreetmap data for Sionna Ray Tracing

This is a utility project which generates Mitsuba compatible 3D scene file along with 3D objects of buildings, Ground and Roads using Openstreetmap data. Files generated using OSM_to_Sionna can be directly used as input to Sionna Ray tracing applications.

Process Overview

It performs following tasks ...

• Presents an interactive map to let user select an area of interst.
• Creates ground, roads and buildings by fetching geo data from openstreetmap using Osmnx library.
• Creates triangulated 3D mesh objects for ground, roads and buildings using PyVista and Open3D libraries
• Finally it creates a Mitsuba 3 format XML scene file by adding materials, colors, light source, Camera etc.
