V-Ray for SketchUp â Materials â The Refraction Layer â V-Ray Tutorials. Refraction means the change of direction of a ray of light in passing at an angle from one medium to another. With V-Ray the refraction layer is used to create glass or translucent materials. How to use the refraction layer to create glass or translucency materials in this video tutorial.
A refractometer is the instrument used to obtain a brix reading. This simple, hand-held measures the amount of refraction (or bend) in a beam of light that passes through the plant sap.rix. Brix is a scale based on the amount that light bends when it passes through a liquid. If one were to place one's hand in a pond and measure the amount it appeared to bend, and then place it in the ocean, it would appear to bend a different amount.
