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.
