ir - set the complex index of refraction for the current material
Set the index of refraction for the current material to
If the material is a dielectric (as opposed to metallic), then
should be zero.
For solid dielectric objects, the material should be made one-sided.
If it is being used for thin objects, then a two-sided
material is appropriate.
The default index of refraction is that of a vacuum, (1,0).
