Coords of overlay

By dynamic I assume you mean while the page is being viewed. We currently do not provide such an API.

If dynamic refers to on loading of page, then you could alter the scene's position by dynamically writing the embed code. If you look through the overlay embed code 2 of the variables are x and y position on the page. We do not recommend this as it could cause the page to load incorrectly if the information is not correctly edited, but a skilled coder would be able to make these changes without harming their site.

Thank you.I understood the way.
