Classes

Rays	Initialize the Rays class.

Module Contents

class artist.scene.rays.Rays(ray_directions: torch.Tensor, ray_magnitudes: torch.Tensor)

Initialize the Rays class.

The rays in ARTIST have a direction vector and a magnitude. They are used for ray tracing. The direction vector determines the direction of the rays, i.e., the path they are taking through space. The magnitude is important for considering atmospheric losses and cloud coverage. If a ray travels through a cloud, the magnitude changes.

Parameters

ray_directionstorch.Tensor

The direction of the rays. Tensor of shape [number_of_active_heliostats, number_of_rays, number_of_combined_surface_normals_all_facets, 4].

ray_magnitudestorch.Tensor

The magnitudes of the rays. Tensor of shape [number_of_active_heliostats, number_of_rays, number_of_combined_surface_normals_all_facets].

Raises

ValueError

If the shapes of the ray directions does not match the shapes of the ray magnitudes.
