Enumerations

enum Operator:

Operator OP_SCREEN = 0

用以下公式产生屏幕效果。

result = vec3(1.0) - (vec3(1.0) - a) * (vec3(1.0) - b);

Operator OP_DIFFERENCE = 1

用以下公式产生差异效果。

result = abs(a - b);

Operator OP_DARKEN = 2

用以下公式产生变暗效果。

result = min(a, b);

Operator OP_LIGHTEN = 3

用以下公式产生减淡效果。

result = max(a, b);

Operator OP_OVERLAY = 4

用以下公式产生叠加效果。

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);
    }
}

Operator OP_DODGE = 5

用以下公式产生闪避效果。

result = a / (vec3(1.0) - b);

Operator OP_BURN = 6

用以下公式产生燃烧效果。

result = vec3(1.0) - (vec3(1.0) - a) / b;

Operator OP_SOFT_LIGHT = 7

用以下公式产生柔光效果。

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));
    }
}

Operator OP_HARD_LIGHT = 8

用以下公式产生硬光效果。

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));
    }
}

Operator OP_MAX = 9

代表 Operator 枚举的大小。
