VisualShaderNodeColorOp
=======================

**Inherits:** :ref:`VisualShaderNode<class_VisualShaderNode>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A :ref:`Color<class_Color>` operator to be used within the visual shader graph.

Description

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:

::

- **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:

::

        float blend = b[i];
        if (base < 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) {

- **OP_MAX** = **9** --- Represents the size of the :ref:`Operator<enum_VisualShaderNodeColorOp_Operator>` enum.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
