Click?

[Aldo111]

Hi, I just started using this (and am a beginner to three.js as well) and I basically wanted to be able to "attach" an image (or possibly a text box - whatever's easier) to a point on this photosphere and it should be able to move with the photosphere and be out of view when not in the photosphere's fov.

What would be the best way to go about this? There is no click event right off the bat and I'm not too sure how I should tackle this in a clean way that would work across different resolutions. My main issue is what positional values should I be using for such attachable elements - and how can I get them upon a click? (Since photospheres use an equirectangular projection, what would be a nice way to convert it to a meaning x/y that could be use to attach elements within the browser window to a specific point on the photosphere image)
