Medium¶
Description¶
A medium describes volumic material properties. Currently, this includes refractive index and light absorption properties, generalized to complex refractive indices or equivalently permittivity (also called dielectric function)
Media also have a precedence parameter, which controls the medium filling a volume in the scene when multiple geometries with different media are overlapping. See modelling volumes for more details
Loading Sopra .nk dielectric functions¶
For using a Sopra .nk file as an Ocean medium, just drag and drop or copy/paste a .nk file on a medium node in the Object editor.
