Enumerations

enum Operator:

  • OP_SCREEN = 0 --- Produce a screen effect with the following formula:
result = vec3(1.0) - (vec3(1.0) - a) * (vec3(1.0) - b);
  • OP_DIFFERENCE = 1 --- Produce a difference effect with the following formula:
result = abs(a - b);
  • OP_DARKEN = 2 --- Produce a darken effect with the following formula:
result = min(a, b);
  • OP_LIGHTEN = 3 --- Produce a lighten effect with the following formula:
result = max(a, b);
  • OP_OVERLAY = 4 --- Produce an overlay effect with the following formula:
for (int i = 0; i < 3; i++) {
    float base = a[i];
    float blend = b[i];
    if (base < 0.5) {
        result[i] = 2.0 * base * blend;
    } else {
        result[i] = 1.0 - 2.0 * (1.0 - blend) * (1.0 - base);
    }
}
  • OP_DODGE = 5 --- Produce a dodge effect with the following formula:
result = a / (vec3(1.0) - b);
  • OP_BURN = 6 --- Produce a burn effect with the following formula:
result = vec3(1.0) - (vec3(1.0) - a) / b;
  • OP_SOFT_LIGHT = 7 --- Produce a soft light effect with the following formula:
for (int i = 0; i < 3; i++) {
    float base = a[i];
    float blend = b[i];
    if (base < 0.5) {
        result[i] = base * (blend + 0.5);
    } else {
        result[i] = 1.0 - (1.0 - base) * (1.0 - (blend - 0.5));
    }
}
  • OP_HARD_LIGHT = 8 --- Produce a hard light effect with the following formula:
for (int i = 0; i < 3; i++) {
    float base = a[i];
    float blend = b[i];
    if (base < 0.5) {
        result[i] = base * (2.0 * blend);
    } else {
        result[i] = 1.0 - (1.0 - base) * (1.0 - 2.0 * (blend - 0.5));
    }
}
