Enumerations

enum Function:

Function FUNC_GRAYSCALE = 0

Converts the color to grayscale using the following formula:

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);

Function FUNC_HSV2RGB = 1

Converts HSV vector to RGB equivalent.

Function FUNC_RGB2HSV = 2

Converts RGB vector to HSV equivalent.

Function FUNC_SEPIA = 3

Applies sepia tone effect using the following formula:

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);

Function FUNC_MAX = 4

Represents the size of the Function enum.
