Field Documentation

◆ cover_transmittance

float PerRayData::cover_transmittance[HELIOS_MAX_RADIATION_BANDS]

Per-launch-band transmittance accumulated as the ray passes through translucent covers (glass/plastic). Initialised to 1 in the raygen programs; multiplied by the Fresnel+Bouguer tau(theta) in the any-hit programs; consumed in the miss programs. Indexed by launch-band b.
