You can zoom in / out with the middle mouse wheel
You can rotate with the right mouse button clicked and moving to rotate
If the model needs to be transformed, there's a "Transform" button on the top of the canvas which will show 3D controls for the model.
Numbers can also be adjusted directly in the "Properties" panel.
I think you ask for a different thing: you want to move and zoom the 3D model in your experience with slider controls similar to the KTM Bike Welcome Experience, right? In fact this is pretty simple. Here are the steps if you want to control the rotation of the model.
- add a slider widget to the 2D overlay of your AR view. Set the min value to 0 and the max value to 360.
- bind the slider value to the model-1 X, Y or Z Rotation property.
If you want to scale the model, you can specify a corresponding max value and bind the slider value to the Scale property of the 3DModel widget.
I hope this description is detailed enough.
