I’m currently get stuck on a problem that placing a 3d object on the canvas but to the right/left.

By adjusting the parameters x, y, z of the camera, I made the 3d be placed to the right of the screen.
However, every device screen gives the 3d’s position differently, which is not in my wanted spot.

Im using this tutorial as a reference to place it in the middle but now I want it to place to the right/left of the screen.

I will be very appreciated if anyone can help me solving this problem.
Many thanks!
