# Normal Map

Transforms a normal vector from object or tangent space into world space.

## Parameter Types

**Normal Map:**

|Input    |Type    |
                |---------|--------|
                |`In`     |Vector3f|
                |`Space`  |String  |
                |`Scale`  |Float   |
                |`Normal` |Vector3f|
                |`Tangent`|Vector3f|

|Output|Type    |
                |------|--------|
                |`Out` |Vector3f|

**Normal Map (vector2f Scale):**

|Input    |Type    |
                |---------|--------|
                |`In`     |Vector3f|
                |`Space`  |String  |
                |`Scale`  |Vector2f|
                |`Normal` |Vector3f|
                |`Tangent`|Vector3f|

|Output|Type    |
                |------|--------|
                |`Out` |Vector3f|

## Parameter descriptions

- `In`: The input vector to be transformed; the default is `(0.5, 0.5, 1.0)`.
- `Space`: The space from which the node transforms the normal vector. The value can either be `object` or `tangent`. The default value is `tangent`.
- `Scale`: A scalar multiplier for the input vector before the node transforms it. The default value is `1.0`.
- `Normal`: The surface normal vector. The default value is the current surface normal of world space.
- `Tangent`: The surface tangent vector. The default value is the current tangent vector of world space.
