openworld_radio_twin.rt

Sionna-compatible loader extended with geographic scene compilation.

Functions

load_scene([filename, merge_shapes, ...])	Load a native Sionna scene from a file, an empty scene, or WGS84 coordinates.
load_scene_async(*, latitude, longitude, ...)	Compile asynchronously, then load the native scene on the caller's event-loop thread.
measurement_surface(scene_or_path, *[, ...])	Return a native Mitsuba mesh following terrain at a constant AGL height.
position(scene_or_path, *, latitude, ...)	Return the absolute ENU position expected by Sionna's radio devices.
scene_frame(scene_or_path)	Restore the scene's public WGS84-to-ENU transform.
scene_path(scene)	Return the canonical directory registered for a native Sionna scene.
terrain_elevation(scene_or_path, east_m, north_m)	Sample local terrain elevation in metres at an ENU position.

openworld_radio_twin.rt.load_scene(filename=None, merge_shapes=True, merge_shapes_exclude_regex=None, remove_duplicate_vertices=False, *, latitude=None, longitude=None, radius_m=None, cache_dir=None, buildings='auto', building_source='auto', terrain='elevation', material_profile='itu', terrain_resolution_m=5.0, device='auto', **sionna_options)

Load a native Sionna scene from a file, an empty scene, or WGS84 coordinates.

async openworld_radio_twin.rt.load_scene_async(*, latitude, longitude, radius_m, cache_dir=None, buildings='auto', building_source='auto', terrain='elevation', material_profile='itu', terrain_resolution_m=5.0, device='auto', merge_shapes=True, merge_shapes_exclude_regex=None, remove_duplicate_vertices=False, **sionna_options)

Compile asynchronously, then load the native scene on the caller’s event-loop thread.

openworld_radio_twin.rt.measurement_surface(scene_or_path, *, cell_size=(10.0, 10.0), height=1.5)

Return a native Mitsuba mesh following terrain at a constant AGL height.

openworld_radio_twin.rt.position(scene_or_path, *, latitude, longitude, height_agl)

Return the absolute ENU position expected by Sionna’s radio devices.
