Currently attempting to select objects when clicked, using the common code found in various examples:
function onMouseDown(evt) {
evt.preventDefault();
canvasAbsoluteHeight = $('canvas').height();
canvasAbsoluteWidth = $('canvas').width();
mouseDown = true;
mouseX = evt.offsetX == undefined ? evt.layerX : evt.offsetX;
mouseY = evt.offsetY == undefined ? evt.layerY : evt.offsetY;
var mouse = new THREE.Vector3();
mouse.x = ( evt.clientX / canvasAbsoluteWidth ) * 2 - 1;
mouse.y = 1 - ( evt.clientY / canvasAbsoluteHeight ) * 2;
mouse.z = 0;
ray = new THREE.Raycaster( mouse, camera );
var intersects = ray.intersectObjects( objects);
console.log('intersects', intersects);
if ( intersects.length > 0 ) {
console.log('intersects', intersects);
}
}
objects is an array of THREE.Object3D that should be selectable.
It seems like there may be a connection with the camera. My camera is under a THREE.Object3D parent for easier manipulation, and the parent object is not positioned at the origin.
Another issue could be that the canvas is not full screen, which could affect the mouse position (it is within a div offset from the page edges).
