Unity Screen / World Coordinates

Calculate ScreenToWorldPoint / WorldToScreenPoint conversion from camera parameters.

Camera Settings

FOV (Vertical)

Resolution Width

Resolution Height

Camera Position X

Camera Position Y

Camera Position Z

Camera Rotation X (Pitch)

Camera Rotation Y (Yaw)

Screen → World

ScreenToWorldPoint equivalent. screen.z is depth (distance from camera)

Screen X

Screen Y

Depth

World: (0, 0, 0)

World → Screen

WorldToScreenPoint equivalent

World X

World Y

World Z

Screen: (960, 540) / Depth: 10

Usage

Enter camera FOV, resolution, position, rotation. Input screen or world coordinates to convert. Simulates Unity's Camera.ScreenToWorldPoint / WorldToScreenPoint in browser.

When to use

Converting UI to world coordinates, calculating raycast from mouse, verifying coordinate conversion with camera settings.

Examples

Screen center (960,540) to world, check where world (0,0,10) appears on screen.

Tips

Screen coords use bottom-left origin. Differs from UI RectTransform.
Useful to verify world coords from RaycastHit.point back to screen.
Camera near/far clip does not affect conversion result.
