Volumetric Scattering full scattering models

The OptiColor materials in the Photopia Library are modeled both as "Transmissive" materials, at their constant 2mm thickenss, and also as "Volumetric Scattering Refractive" materials which can be applied to any lens part.

  • Transmissive materials - faster raytraces, limited to measured thickness, should only be applied to flat parts
  • Volumetric Scattering Refractive materials - can be used with variable thickness and parts with prismatic geometry, more detailed raytrace

Transmissive Material Behavior
All of the scattering for the measured 2mm thick sample occurs at the face of the surface

Volumetric Scattering Behavior
Light interacts with particles throughout the material thickness, properly accounting for thick and thin sections of your part.
