as can see can navigate in space , change camera position right , left mouse button. able come initial camera position (earth in center of screen) double click on planet.

why didn't had success adapting example? errors occuring? did mean this example? because raycaster , projector way looking for.

first of need eventlistener ondblclick event on container. in event function can copy&paste linked example:

1) saving mouse coordinates

mouse.x = ( event.clientx / window.innerwidth ) * 2 - 1; mouse.y = - ( event.clienty / window.innerheight ) * 2 + 1; 

2) project coordinates world system via camera , create ray

var vector = new three.vector3( mouse.x, mouse.y, 1 ); projector.unprojectvector( vector, camera ); raycaster.set( camera.position, vector.sub( camera.position ).normalize() ); 

3) check if double clicked element planet

var intersects = raycaster.intersectobject( "your_planet" ); if ( intersects.length > 0 ) {     reset camera } 

hope helps!
