# Normal

The geometric normal of the currently-processed data in a given coordinate space.

## Parameter Types

|Input  |Type  |
        |-------|------|
        |`Space`|String|

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

## Parameter description

- `Space`: The coordinate space in which the shader defines the normal vector. The default value is `object`.

## Discussion

Valid values for the `Space` parameter include the following:

- `model`: The local coordinate space before the shader applies any local deformations or global transforms to the geometry.
- `object`: The local coordinate space after the shader applies local deformations but before it applies global transforms to the geometry.
- `world`: The global coordinate space after the shader applies both local deformations and global transforms to the geometry.
