Refraction Diffuse

Category: Processing > Raytracing

Shader Family: Texture

Output: Color

Calculates diffuse refractions from an object's surface. Instead of perfect refractions (like those occurring off a smooth window), diffuse reflections break up the colors that refract off a textured surface like frosted glass. Multiple jittered refraction rays are cast, and the result is combined into the final "refracted color."

Name	The shader's name. Enter any name you like, or leave the default.

Refraction

Input	Specifies the surface color. These values are combined with the refraction color according to the Refraction parameter (below).
Refraction	Specifies the refraction intensity for each color channel (RGB — refraction of each color is controlled separately instead of a single scalar "transparency" control).
Index of Refraction	Controls the index of refraction, which determines the direction of the incoming ray. The IOR is typically set to 1.0 for air, 1.33 for water, and 1.52 for glass.
Maximum Depth	Deprecated.
Alpha	Uses the alpha channel, instead of the RGB channels, to control the refraction intensity.

Gloss

Glossy	Specifies how glossy or diffuse the transparency is. Higher values make the transparency more diffuse but require higher sampling counts.
Samples	Specifies the number of times the transparency is oversampled. Higher glossy values require more sampling.

Render Tree Usage

Use this shader to either alter an input color value (surface shader, image clip, texture), affect a specific color parameter (diffuse, transparency, specular), or both.
