Public Members

const emitter::emitter_t *emitter = nullptr¶: Sampled emitter.

f_t emitter_pdf = 0¶: Sampling probability mass of sampled emitter. This field is only populated by the scene-wide direct sampler wt::scene_t::sample_emitter_direct(), and not by the individual wt::emitter::emitter_t::sample_direct() of emitters.

solid_angle_sampling_pd_t dpd¶: Density of direct connection.
