I tried adding texture to my cube I made using JS/THREE.JS.
But when I open it up in my browser its all black?
This is my code:
<html>
<head>
<title>My first Three.js app</title>
<style>canvas { width: 100%; height: 100% }</style>
</head>
<body>
<script src="https://rawgithub.com/mrdoob/three.js/master/build/three.js"></script>
<script>
// revolutions per second
var angularSpeed = 0.2;
var lastTime = 0;
// this function is executed on each animation frame
function animate(){
// update
var time = (new Date()).getTime();
var timeDiff = time - lastTime;
var angleChange = angularSpeed * timeDiff * 2 * Math.PI / 1000;
cube.rotation.y += angleChange;
lastTime = time;
// render
renderer.render(scene, camera);
// request new frame
requestAnimationFrame(function(){
animate();
});
}
// renderer
var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
// camera
var camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 1000);
camera.position.z = 500;
// scene
var scene = new THREE.Scene();
// material
var material = new THREE.MeshLambertMaterial({
map: THREE.ImageUtils.loadTexture('crate.jpg')
});
// cube
var cube = new THREE.Mesh(new THREE.CubeGeometry(200, 200, 200), material);
cube.overdraw = true;
cube.rotation.x = Math.PI * 0.1;
scene.add(cube);
// add subtle ambient lighting
var ambientLight = new THREE.AmbientLight(0xbbbbbb);
scene.add(ambientLight);
// directional lighting
var directionalLight = new THREE.DirectionalLight(0xffffff);
directionalLight.position.set(1, 1, 1).normalize();
scene.add(directionalLight);
// start animation
animate();
</script>
</body>
</html>
I used this guide to do it:
http://www.html5canvastutorials.com/three/html5-canvas-webgl-texture-with-three-js/
It might be because of having MeshLambertMaterial which needs ambient light, which you have but it may not be set correctly. Try using MeshBasicMaterial instead.
I've tested the same code you put and it works perfectly.
The only thing I've changed is the path to the image:
map: THREE.ImageUtils.loadTexture('img/textures/test.png')
Double check that the image is located in the current folder and if it is, try with another image (this one works perfect for me: https://aec-apps.com/sites/default/files/styles/app_160_160/public/Screen%20Shot%202013-10-25%20at%2000.28.49.png).
Hope it helps!

I'm really new in Three.js and javascript in general.
My question, I'm been trying to create some king of basic frankenstein template ( mainly based on Lee Stemkoski's examples) to use Three.js but as right know i can't make the cube spin infinitely, I have been watching tutorials and other examples but i can't make it work, any ideas why or how to solve it?
And
Any suggestions on how to improve this template scene?
Thanks in advance

To rotate your cube you'll need to add some value to the cube's rotation every frame. The reason this didn't work when you did it before is that the cube is defined in your init function and the render function doesn't have a reference to it.
So your fix requires two things:
Define your cube in a scope that both methods can "see"
Add some value to the rotation of your cube every frame
Inside of the init function you're defining your cube as mesh, so rename this to cube and remove var:
//Join the two attribute ( Geometry and material )
//var mesh = new THREE.Mesh( geometry, material); // Old
cube = new THREE.Mesh( geometry, material); // new
Removing var causes cube to become a global variable defined on the dom window rather than the init function. So your render function can "see" cube. So now all you have to do is rotate it!
function render()
{
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render( scene, camera );
}
I hope that helps!
and if you'd like to learn more about scope give this link a good read, it's helped me quite a bit.

I ctrl + f'd the code, and you don't reference the rotation of the cube once. That would explain why it's not rotating. You can't will it to rotate, you need to actually write something that will change the values of the elements in your scene.
In order to continuously change the rotation of something, you need to reference or increment its rotation in the part of the code that loops.
I load some objects using the ctm binary loader in Threejs r69. This returns Mesh objects using a BufferGeometry internally.
I need to remove from the scene then delete one of these Meshes, including their material/texture/geometry. According to examples and google, I should use:
scene.remove(m_mesh);
m_mesh.geometry.dispose();
m_mesh.geometry = null;
m_mesh.material.dispose();
m_mesh.material = null;
m_mesh = null;
This removes the object from the scene, but the screen goes black for a second, and I've got a GL error :
Error: WebGL: drawElements: no VBO bound to enabled vertex attrib index 2!
Looks like the above sequence (ran in my render() operation, just before drawing the scene) did not clean everything, or at least I still have references to non existing VBOs somewhere.
I've spent quite some time debugging the problem and came to the conclusion that this happens only when using an orthographic camera with a Sprite and a Perspective camera, in 2 differents scenes.
Basically, I draw a flat background using a Sprite and a dedicated scene, then my 3D scene with Meshes. If I delete a mesh from the 3D scene, then the drawing of the flat background fails.
I can't figure out why. Looks like there's a side effect of deleting a Mesh on Sprites, even if attached to different scenes.
If I comment the background drawing, then the deletion of my mesh works perfectly.
I insert below a reproduction of the problem using the standard threejs distribution. Wait about 5 seconds and you should see some GL errors on the jaavscript console.

I'm just learning how to do this three.js magic. I'm able to draw and animate a cube. But when I change the geometry to an Icosahedron nothing appears.
Inside my js src forlder I only have the three.min.js file. Do I need another .js file in there?
Here is a sample of my code. I'm just a beginner, and have been spending hours trying to figure this out. Please help.

document.body.appendChild(renderer.domElement);
/*var geometry = new THREE.BoxGeometry(1,1,1);
var material = new THREE.MeshLambertMaterial({color: 0x00ff00});
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);*/
var geometry = new THREE.IcosahedronGeometry( 200,1 );
var material = new THREE.MeshBasicMaterial( { color: 0x00ff00, wireframe: false, wireframeLinewidth: 2 } );
var mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
var pointlight = new THREE.PointLight(0xffffff);
pointlight.position.x = 10;
pointlight.position.y = 50;
pointlight.position.z = 1000;
scene.add(pointlight)
camera.position.z = 5;
var render = function () {
requestAnimationFrame(render);
cube.rotation.x += .01;
cube.rotation.y += .01;
renderer.render(scene, camera);
};
render();

I'm just beginning to experiment with THREE.js. I'm trying different combinations of renderers and cameras.
I can render a simple animation using the WebGLRenderer and the OrthographicCamera or the CanvasRenderer and the PerspectiveCamera. But if I use the CanvasRenderer with the OrthographicCamera I don't see any image rendered.
Should the CanvasRenderer work with the OrthographicCamera? Fiddles that work are here:
http://jsfiddle.net/PXxLq/ - WebGL/Orthographic - OK
http://jsfiddle.net/fXsKq/ - Canvas/Perspective - OK
This is the code that fails:

For CanvasRenderer, when using OrthographicCamera, the near plane must be negative.
This appears to be a bug.
EDIT: This bug has been fixed. The near plane should always be positive now.

You are calling
renderer.render( scene, camera );
only once, and probably before the texture completes loading.
Add an animation loop.
function animate() {
requestAnimationFrame( animate );
renderer.render( scene, camera );
}
animate();
