Coated diffuse material¶
Description¶
This material simulates an absorbing dielectric layer with a diffuse backing paint, or similarly a diffuse material coated with a perfectly smooth colored varnish. It handles exactly multiple reflections within the layer, and may have a custom interface law such as an interferential coating. This material type models accurately and efficiently enameled or painted glass panes, with exact colorimetry.
