How can I locate ThreeJS coordinates within the Panoramic GUI?

While I've dabbled with ThreeJS in the past, I'm currently working on a new project that involves setting up hotspots in a panoramic view. I vaguely recall using the camera dolly tool from this link to visualize camera locations. However, I'm curious if there's a tool available that could provide XYZ coordinates for specific points in scenarios like the one showcased in this ThreeJS example: example link, particularly for placing hotspots on the road.

An ideal solution would mimic the functionality of the dat gui tool utilized by the camera dolly, or perhaps involve a draggable ball element that can display its current location.

Answer №1

Do you need help converting a panoramic image into 3d location for saving and rendering purposes? I have a solution that may work for you.

Check out this code snippet for the location calculation: https://jsfiddle.net/mz7Lv9dt/1 (edit: corrected typo)

The crucial part is outlined below:

var raycaster = new THREE.Raycaster();
raycaster.setFromCamera( uv, cam );
return raycaster.intersectObjects( objects );

Move the green ball on the screen to determine its precise location (set at a unit length of one).

If my response doesn't meet your needs, please inform me.
