ColourShader
public sealed class NoisePixelShader : ColourShader
Implements a per-pixel noise shader.

Constructors

NoisePixelShader

#
public NoisePixelShader(double strength, float alpha)
Create a new noise shader.
Parameters:
strength (double)Strength of noise, measured as normalised deviation from 50% grey.
alpha (float)Amount of alpha in each noise value.

Methods

ColourAt

#
public override Color ColourAt(Ray ray, IObjectStack stack)
Evaluate this shader at a specific ray location.
Parameters:
ray (Ray)Coincident ray.
stack (IObjectStack)Object stack context.
Overrides: ColourShader.ColourAt

Dilate

public ColourShader Dilate(double sx, double sy)
Apply a dilation (or scaling) transformation to this shader.
inherited fromColourShader
Parameters:
sx (double)Horizontal dilation.
sy (double)Vertical dilation.
Returns: Dilated shader.

Fade

public ColourShader Fade(ValueShader transparency, bool combine)
Add a transparency layer to this shader.
inherited fromColourShader
Parameters:
transparency (ValueShader)Transparency layer.
combine (bool)If true, overlay transparency is combined with existing transparency. If false, overlay transparency overrules the existing transparency.
Returns: Modified shader.

Fade

public ColourShader Fade(ValueShader transparency)

inherited fromColourShader
Parameters:
colour (Color)Colour to resolve.
ray (Ray)Ray associated with colour location.
stack (IObjectStack)Object stack context.
Returns: Resolved colour.

Rotate

public ColourShader Rotate(Angle angle)
Apply a rotation transformation to this shader.
inherited fromColourShader

Apply a custom transformation to this shader.
inherited fromColourShader
Parameters:
transform (Transform2D)Transformation.
Returns: Transformed shader.

Translate

public ColourShader Translate(double dx, double dy)
Apply a translation transformation to this shader.
inherited fromColourShader
Parameters:
dx (double)Horizontal translation.
dy (double)Vertical translation.
Returns: Translated shader.
