# Py5Graphics.screen_y()

Takes a three-dimensional X, Y, Z position and returns the Y value for where it will appear on a (two-dimensional) screen.

## Description

Takes a three-dimensional X, Y, Z position and returns the Y value for where it will appear on a (two-dimensional) screen.

This method is the same as [](sketch_screen_y) but linked to a `Py5Graphics` object. To see example code for how it can be used, see [](sketch_screen_y).

Underlying Processing method: PGraphics.screenY

## Signatures

```python
screen_y(
    x: float,  # 3D x-coordinate to be mapped
    y: float,  # 3D y-coordinate to be mapped
    /,
) -> float

screen_y(
    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
```
