Web20. júl 2024 · Refraction is a test that optometrists and ophthalmologists use to measure a person's refractive error . A refractive error is when your eye does not bend the light coming into your eye properly as it passes through the cornea, the crystalline lens, and fluid media to come to a sharp, clear focus onto your retina. 1 Zero Creatives / Getty Images WebHDRP uses the refraction model to determine the deviated light direction and the distance that light travels within the Material. HDRP then ray cast against a probe proxy volume ( Proxy Raycasting) to find the hit point of the refracted light ray. Using Refraction To set up refraction on your Material, you need to do the following:
