Mars 3D demo learn Control Camera / Sound Js Call Learn

Hello! My first post here. In a quick introduction i design and produce 360º photography virtual tours at wide.pt

I´ve been trying to mix 360º (with panotour software) and 3D for a while btw the tools for non programmers are not easy and finally after a lot of research and diving into the demo of verge3d i see that verge 3D do the job!

To start the experience and learn (planets are good to learn to apply in other scenarios),so the worlflow was : doing mars in 3dsmax, small hotspot: on click opens a tooltip, onclick on the tooltip goes to 360º of mars. Playing with div´s and simple js. Everything ok here.

In the example, panotour software for transition between 360 to 3D i add the feature “jscall” in a button/hotspot “fadeOut(tourDIV);” with the follow code this makes the transition easy:

<script type="text/javascript">
function fadeOut(tourDIV) {
        $("#tourDIV").fadeOut(400),
	$("#container").delay(1250).fadeIn(600);   
}
</script>

So my question is how can we communicate with verge 3d with a external jscall function for a camera tween movement, and stop sound.

I confess that is very difficult to see examples/tutorials or code to make very simple things and im struggled here.
