A [Color] function to be used within the visual shader graph.
Accept a [Color] to the input port and transform it according to [member function].
- A function to be applied to the input color. See [enum Function] for options.
Converts the color to grayscale using the following formula: [codeblock] vec3 c = input; float max1 = max(c.r, c.g); float max2 = max(max1, c.b); float max3 = max(max1, max2); return vec3(max3, max3, max3); [/codeblock]
Converts HSV vector to RGB equivalent.
Converts RGB vector to HSV equivalent.
Applies sepia tone effect using the following formula: [codeblock] vec3 c = input; float r = (c.r * 0.393) + (c.g * 0.769) + (c.b * 0.189); float g = (c.r * 0.349) + (c.g * 0.686) + (c.b * 0.168); float b = (c.r * 0.272) + (c.g * 0.534) + (c.b * 0.131); return vec3(r, g, b); [/codeblock]
Represents the size of the [enum Function] enum.
