THREE.js Triangle is Black

Question

So i was using THREE.JS and created a triangle. But even though i gave it color: 0xFF0000, it appears black on Screen.

Here is my Script:

var camera, scene, renderer;
var geometry, material, mesh;

init();
animate();

function init() {

    scene = new THREE.Scene();
    camera = new THREE.PerspectiveCamera(35, window.innerWidth / window.innerHeight, 1, 10000);
    camera.position.z = 500;
    scene.add(camera);

    var geometry = new THREE.Geometry(200,200,200);
    var v1 = new THREE.Vector3(200,0,0);   // Vector3 used to specify position
    var v2 = new THREE.Vector3(-100,0,0);
    var v3 = new THREE.Vector3(0,50,0);   // 2d = all vertices in the same plane.. z = 0

    // Push vertices represented by position vectors
    geometry.vertices.push(v1);
    geometry.vertices.push(v2);
    geometry.vertices.push(v3);

    // Push face, defined with vertices in counter clock-wise order
    geometry.faces.push(new THREE.Face3(0, 2, 1));

    // Create a material and combine with geometry to create our mesh
    var redMat = new THREE.MeshLambertMaterial({color: 0xFF0000});
    var triangle = new THREE.Mesh(geometry, redMat);
    scene.add(triangle);

    renderer = new THREE.CanvasRenderer();
    renderer.setSize(window.innerWidth, window.innerHeight);

    document.body.appendChild(renderer.domElement);

}

function animate() {

    requestAnimationFrame(animate);
    render();

}

function render() {

    renderer.render(scene, camera);

}

Hope you can find the mistake i made. I am sure it's just something really stupid.

Answer 1

late to the party...but for all who come after me. The issue here is the type of material used

change

new THREE.MeshLambertMaterial({color: 0xFF0000});

to

new THREE.MeshBasicMaterial({color: 0xFF0000});

and it will show up red
