I'm currently working on a project that involves making 3Dobjects in Threejs, based of databases.
I already have the connection etc, but it keeps failing when I try to create a new object.
this.type = 'CustomObject';
let shape = new THREE.Shape();
const maxSize = coords.reduce((prev, current) => (Math.abs(prev.value) > Math.abs(current.value)) ? prev : current); // max Size but Abs
// console.log("Max size before check : "+ maxSize.value);
//Check weither maxSize is positive or negative.
let height = Math.abs(maxSize.value);
shape.moveTo(0, 0);
for (let i = 0; i < coords.length; i++) {
// console.log(coords[i]);
shape.lineTo(coords[i].id, coords[i].value);
}
shape.lineTo(coords[coords.length - 1].id, -height - 3);
shape.lineTo(0, -height - 3);
shape.lineTo(0, 0);
// let geometry = new THREE.ExtrudeGeometry( shape, extrudeSettings );
let extrudeSettings = {
steps: 4,
amount: 20,
bevelEnabled: false,
bevelThickness: 1,
bevelSize: 1,
bevelSegments: 1
};
this.geometry = new THREE.ExtrudeGeometry(shape, extrudeSettings);
this.material = new THREE.MeshBasicMaterial({color: 0xCbcbcb});
let object = new THREE.Mesh( this.geometry, this.material );
this.createdGraph = object;
console.log(this.createdGraph.Object3D);
this.scene.add(this.createdGraph);
}
This is just part of the code, I know it's not the best. But I would like to work it before I clean it. It's writen with ES6 in mind.
The problem is that if you execute the code, it does create the figure I'd like to have.
A screengrab of the object created by the code.
But if I try to add it to A-Frame ( because I've worked with it before), it keeps giving me the error that I can't add an object without an Object3D to the scene or 'this.updateMorphTargets is not a function ' .
Anyone have any ideas ?
PS I've also tried this https://stackoverflow.com/a/31924233 idea, but that comes back with the ' this.updateMorphTargets is not a function' error.
Thanks :)
I'm not sure which parts give you the error,
I've copied Your code to a fiddle, added 3 coords, and it's working .
Judging from Your code, You've got bad scene references, in a-frame it's
this.el.sceneEl
assuming this
is any entity, and this.scene
does not refer to the scene.
Furthermore refer to three.js objects as object3D
, not Object3D
<a-entity foo> </a-entity>
and placed an entity:
<a-entity foo> </a-entity>
this.el.sceneEl.object3D.add(object)
