Visiblespace generates a matrix stack of visible space for each element, indexed by source_coordinate.
- Parameters:
source_coords (n by 3 numpy array of floats) – xyz coordinates of the sources
source_normals (n by 3 numpy array of floats) – normal vectors for each source point
environment (
lyceanem.base_classes.triangles) – blocking environmentvertex_area (float or array of floats) – the area associated with each source point, defaults to 0, but can also be specified for each source
az_range (array of float) – array of azimuth planes in degrees
elev_range (array of float) – array of elevation points in degrees
shell_range (float) – radius of point cloud shell
- Returns:
visible_patterns (m by l by n array of floats) – 3D antenna patterns
resultant_pcd (open3d pointcloud) – colour data to scale the points fractional visibility from the source aperture
- lyceanem.raycasting.rayfunctions.workchunkingv2(sources, sinks, scattering_points, environment, max_scatter, line_of_sight=True)[source]
Raycasting index creation and assignment to raycaster, upper bound is around 4.7e8 rays at a time, there is already chunking to prevent overflow of the GPU memory and timeouts
- Parameters:
- Returns:
full_index (2D numpy array of ints) – the index for all successful rays cast from source coordinates, to any scattering points, to the sink point for each entry
RAYS_CAST (int) – the number of rays cast in this launch.
