# Objective
- In `Camera::viewport_to_world_2d`, `Camera::viewport_to_world`,
`Camera::world_to_viewport` and `Camera::world_to_viewport_with_depth`,
the results were incorrect when the `Camera::viewport` field was
configured with a viewport position that was non-zero. This PR attempts
to correct that.
- Fixes#16200
## Solution
- This PR now takes the viewport position into account in the functions
mentioned above.
- Extended `2d_viewport_to_world` example to test the functions with a
dynamic viewport position and size, camera positions and zoom levels. It
is probably worth discussing whether to change the example, add a new
one or just completely skip touching the examples.
## Testing
Used the modified example to test the functions with dynamic camera
transform as well as dynamic viewport size and position.
