mouse move group

[wizarden]

group = new THREE.Object3D(); group.add( cube1,cube2 ); mouseMove.objects.push(group); //??? how to assign to a group scene.add( group );//it works

Hi, thanks for rising this topic up, the code does not consider hierarchies. In your example group will be used as a target for raytracing. Group has no mesh to raytrace, it will be skipped.

Please see working example here: http://jsfiddle.net/mmalex/uqy1dzrt/

ClipperLib??

[nmalex]

You can ignore clipper for this case, just see how RayysMouseMove and RayysMouse are initialized and connected to callbacks

let points = shape.getPoints(3);??

We are trying to compose a group of objects that have parametric parameters. We can’t unite in groups. Like in this video

[nmalex]

Here's your how the hierarchy is created:

var geometry = new THREE.BoxGeometry( 1, 1, 1 );
var material = new THREE.MeshBasicMaterial( {color: 0x009000} );
var cube0 = new THREE.Mesh( geometry, material );
var cube1 = new THREE.Mesh( geometry, material );
cube1.position.set(2,0,0)
var cube2 = new THREE.Mesh( geometry, material );
cube2.position.set(-2,0,0)
cube0.add( cube1,cube2 );
mouseMove.objects.push(cube0);
scene.add(cube0);

.recursive flag in https://threejs.org/docs/#api/en/core/Raycaster.intersectObject has to be set true, so that it would let raycaster pick by parent and all children too.

In mouse down even handler:

        this.pickPoint = intersects[0].point;
        let pickedObj = intersects[0].object
        if (this.objects.indexOf(pickedObj) !== -1) {
            this.pickedObj = pickedObj; // parent object was picked directly
        } else { // find out if picked object has manipulatable parent,
          let pickedParent = pickedObj.parent;
          while (pickedParent) {
            if (this.objects.indexOf(pickedParent) !== -1) {
                this.pickedObj = pickedParent; // set pickedObj to parent, if exists
              break;
            }
            pickedParent = pickedParent.parent;
          }
          if (!this.pickedObj) {
            return;
          }
        }

Working example see here: http://jsfiddle.net/mmalex/bug5t8qe/

cube0.add( cube1,cube2 );
thank make cube0 the size of the whole group and make invisible material

I've tried to move around the axes, but I've come to a dead end. Could you push or tell me which direction to take?

Yes, but here we choose between one or two axes. Is it possible to select on click axes as in this example.

Added to RayysMouseMove I now have a conditional move over XYZ but it works satisfactorily

if (mode === 'xyz') { this.translationLimits.set(1, 1, 1); this.translationPlane.normal.set(1,1,1); this.translationPlaneHelper.color = 0xffff00;

}
