Description

This model tests the effects of the KHR_materials_dispersion extension.

Dispersion requires volumetric transmission (KHR_materials_transmission with KHR_materials_volume) and also scales with IOR (KHR_materials_ior). It changes the effective IOR values for different frequencies of light, producing an effect known as chromatic aberration. In the right-most column, the rainbow-like effect is most pronounced.
