Question

I understand there is no THREE.projector in version 71 (see the deprecated list), but I don\'t understand how to replace it, particularly in this code that dete

Answer 1

The THREE.JS raycaster documentation actually gives all the relevant information that is laid out in these answers as well as all the missing points that may be difficult to get your head around.

var raycaster = new THREE.Raycaster(); 
var mouse = new THREE.Vector2(); 

function onMouseMove( event ) { 
  // calculate mouse position in normalized device coordinates 
  // (-1 to +1) for both components 
  mouse.x = ( event.clientX / window.innerWidth ) * 2 - 1; 
  mouse.y = - ( event.clientY / window.innerHeight ) * 2 + 1; 
} 

function render() { 
  // update the picking ray with the camera and mouse position
  raycaster.setFromCamera( mouse, camera ); 
  // calculate objects intersecting the picking ray var intersects =     
  raycaster.intersectObjects( scene.children ); 

  for ( var i = 0; i < intersects.length; i++ ) { 
    intersects[ i ].object.material.color.set( 0xff0000 ); 
  }

  renderer.render( scene, camera ); 
} 
window.addEventListener( 'mousemove', onMouseMove, false );        
window.requestAnimationFrame(render);`

Hope it helps.
