Detailed Description

A differential directional light source.

A differential directional light source contains two RSMs \( \mu \) and \( \rho \):

• \( \rho \) is an RSM of a scene with an additional object
• \( \mu \) is an RSM of the same scene without the additional object

Having these two RSMs, the differential indirect bounce can be extracted by subtracing \( \mu \) from \( \rho \). This class is used to intialize delta_light_propagation_volume objects or delta_sparse_voxel_octree objects.
