I’ve noticed that 2D mouse coordinates are not the same as 3D object coordinates. So it’s difficult to move a 3D object with the 2D mouse. I figured out a basic formula but when I scale the 3D object the simple formula no longer works. I’ve looked at a lot of different code to help me figure this out but it all seems to complicated for me at my present level of 3D programming knowledge. Is there a simple formula that takes the 3D object’s scale into account?

Thanks
