Refraction modeling

Refraction modeling

Hello,

My question: I would like to render a scene with refraction of few interfaces. In the forum I've found quick note that this has to be done on XML and BIN level, rather than on OBJ and MTL. Is there an example of how to specify a transparent material with different refractive index? I'm particularly interested in flat interfaces with materials are either large parallelepipeds or semi-infinite.

Would greatly appreciate any pointer or advice.

Cheers,

For more complete information about compiler optimizations, see our Optimization Notice.

The crown model uses glass materials. Download it from here https://github.com/embree/models/releases/download/release/crown.zip and look for Dielectric-type materials in the XML file.
