KaleidoscopeEffect

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

A pixel shader effect that folds its input into mirrored wedges around a centre point, the way a kaleidoscope folds whatever it is pointed at.

public class KaleidoscopeEffect : ShaderEffect

Inherits from / implements: ShaderEffect

Remarks

Animate Rotation to turn the barrel; the picture keeps its symmetry while the content sweeps through it. SegmentCount is settable at any time but is meant to be chosen rather than animated - changing it mid-animation re-cuts the wedges and reads as a jump.

Members at a glance

`KaleidoscopeEffect`	Initializes a new instance of the `KaleidoscopeEffect` class.
`CenterXY`	The point the wedges radiate from, in texture coordinates, where (0,0) is the top left of the element and (1,1) the bottom right.
`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.
`Rotation`	How far the fold is turned, in radians. Animate this to rotate the pattern.
`SegmentCount`	How many mirrored wedges the picture is folded into. Values below one are treated as one, which leaves the input unfolded.
`CenterXYProperty`	Identifies the `CenterXY` dependency property.
`InputProperty`	Identifies the `Input` dependency property.
`RotationProperty`	Identifies the `Rotation` dependency property.
`SegmentCountProperty`	Identifies the `SegmentCount` dependency property.

Properties

CenterXY

public Point CenterXY

The point the wedges radiate from, in texture coordinates, where (0,0) is the top left of the element and (1,1) the bottom right.

Input

public Brush 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.
