Hi everyone,  
I have a json that returns an object position in 2d coordinates with his previous width and height of image. I would like to transform this 2d coordinates in 3d but proportionally to new width and height dimensions (width: 1920, height: 1080) in threeJS. Could someone help me? Thanks.

```javascript
"image": {
					"width": 2300,
					"height": 1416,
					"x": 50,
					"y": 200
				}

```
