# Py5Graphics.screen_x()
Takes a three-dimensional X, Y, Z position and returns the X value for where it will appear on a (two-dimensional) screen.
## Description
Takes a three-dimensional X, Y, Z position and returns the X value for where it will appear on a (two-dimensional) screen.
This method is the same as [](sketch_screen_x) but linked to a `Py5Graphics` object. To see example code for how it can be used, see [](sketch_screen_x).
Underlying Processing method: PGraphics.screenX
## Signatures
```python
screen_x(
x: float, # 3D x-coordinate to be mapped
y: float, # 3D y-coordinate to be mapped
/,
) -> float
screen_x(
x: float, # 3D x-coordinate to be mapped
y: float, # 3D y-coordinate to be mapped
z: float, # 3D z-coordinate to be mapped
/,
) -> float
```
