FrostedGlassEffect

class.NET 6 / 8 / 10.NET Framework 4.8Binarymission.WPF.Shaders.Library.CustomEffects

A pixel shader effect that scatters each pixel of its input by a small pseudo-random amount, which reads as frosted or etched glass laid over it.

public class FrostedGlassEffect : ShaderEffect

Inherits from / implements: ShaderEffect

Remarks

The randomness is computed from the coordinate rather than sampled from a noise texture, so the effect ships as a shader and nothing else. That also makes the scatter fixed for a given Seed: animate the seed, not just the frostiness, to make the glass shimmer.

Members at a glance

`FrostedGlassEffect`	Initializes a new instance of the `FrostedGlassEffect` class.
`Frostiness`	How far a pixel may be displaced, in texture coordinates. A useful range is about 0.002 to 0.05; beyond that the input stops being readable.
`Input`	The image this effect is applied to. It is set for you when the effect is attached to an element; set it directly only when using the effect as a brush.
`Seed`	Shifts the scatter pattern. Any value gives a different arrangement of the same frostiness, so animating it shimmers the glass without changing how rough it looks.
`FrostinessProperty`	Identifies the `Frostiness` dependency property.
`InputProperty`	Identifies the `Input` dependency property.
`SeedProperty`	Identifies the `Seed` dependency property.
