# Screen Position Node
|
|
|
|
## Description
|
|
|
|
Provides access to the mesh vertex or fragment's **Screen Position**. The mode of output value can be selected with the **Mode** dropdown parameter.
|
|
|
|
**Default**
|
|
|
|
Returns **Screen Position**. This mode divides **Screen Position** by the clip space position W component.
|
|
|
|
**Raw**
|
|
|
|
Returns **Screen Position**. This mode does not divide **Screen Position** by the clip space position W component. This is useful for projection.
|
|
|
|
**Center**
|
|
|
|
Returns **Screen Position** offset so position `float2(0,0)` is at the center of the screen.
|
|
|
|
**Tiled**
|
|
|
|
Returns **Screen Position** offset so position `float2(0,0)` is at the center of the screen and tiled using `frac`.
