How to use ViewHelper, Gizmo

[neming81]

Hello, I want to create a shaft helper related to ViewHelper, Gizmo in o3dv, but if I try to apply ViewHelper, Gizmo.. There was a collision with three.js built in o3dv.website.min.js and two canvas id="viewer" data-engine codes, so ViewHelper, Gizmo does not recognize the three in o3dv.website.min.js and cannot use it because it recognizes the canvas of the newly loaded three.js
Is there a way to load three.js built in o3dv.website.min.js or a way to use ViewHelper, Gizmo even if I load a separate three.js? I am not good at English. I use a translator to write.
