i am using threejs with my colladaLoader, and my model displays fine except for the fact that the ambient light or something related makes it dark sometimes.. the light comes and goes. with the following code, how can i disable this behavior and make is lighting constant and bright?
CODE:
if ( ! Detector.webgl ) Detector.addGetWebGLMessage();
var container, stats;
var camera, scene, renderer, objects;
var particleLight, pointLight;
var skin;
function load_model(el,model_url,type) {
window.loader = new THREE.ColladaLoader();
window.loader.options.convertUpAxis = true;
window.imageReplace = [{"name":"stock.jpg","new_image":"colors/generated_color.png"}];
window.loader.load( model_url, imageReplace, function ( collada ) {
//console.log(collada);
dae = collada.scene;
skin = collada.skins[ 0 ];
dae.scale.x = dae.scale.y = dae.scale.z = 0.040;
dae.updateMatrix();
//setMaterial(dae, new THREE.MeshBasicMaterial( { map: THREE.ImageUtils.loadTexture( "/media/images/stock.jpg") } ));
window.init(el);
window.animate();
} );
window.init = function(el) {
container = document.createElement( 'div' );
el.append( container );
camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 2000 );
camera.position.set( 2, 2, 3 );
scene = new THREE.Scene();
// Add the COLLADA
scene.add( dae );
particleLight = new THREE.Mesh( new THREE.SphereGeometry( 4, 8, 8 ), new THREE.MeshBasicMaterial( { color: 0xffffff } ) );
scene.add( particleLight );
// Lights
// scene.add( new THREE.AmbientLight( 0xFFFFFF ) );
var directionalLight = new THREE.DirectionalLight(/*Math.random() * 0xffffff*/0xeeeeee );
directionalLight.position.x = Math.random() - 0.5;
directionalLight.position.y = Math.random() - 0.5;
directionalLight.position.z = Math.random() - 0.5;
directionalLight.position.normalize();
scene.add( directionalLight );
// pointLight = new THREE.PointLight( 0xffffff, 4 );
// pointLight.position = particleLight.position;
// scene.add( pointLight );
renderer = new THREE.WebGLRenderer();
if ( type =='edit')
renderer.setSize( window.innerWidth/2, window.innerHeight/2 );
else
renderer.setSize( window.innerWidth/3, window.innerHeight/3 );
container.appendChild( renderer.domElement );
// stats = new Stats();
// stats.domElement.style.position = 'absolute';

if ( type =='edit')
renderer.setSize( window.innerWidth/2, window.innerHeight/2 );
else
renderer.setSize( window.innerWidth/3, window.innerHeight/3 );
}
//

var clock = new THREE.Clock();
window.animate = function() {
var delta = clock.getDelta();
requestAnimationFrame( animate );
if ( t > 1 ) t = 0;
if ( skin ) {
// guess this can be done smarter...
// (Indeed, there are way more frames than needed and interpolation is not used at all
// could be something like - one morph per each skinning pose keyframe, or even less,
// animation could be resampled, morphing interpolation handles sparse keyframes quite well.
// Simple animation cycles like this look ok with 10-15 frames instead of 100 ;)
for ( var i = 0; i < skin.morphTargetInfluences.length; i++ ) {
skin.morphTargetInfluences[ i ] = 0;
}
skin.morphTargetInfluences[ Math.floor( t * 30 ) ] = 1;
t += delta;
}
window.render();
//stats.update();
}
window.render = function() {
var timer = Date.now() * 0.0005;
camera.position.x = Math.cos( timer ) * 10;
camera.position.y = 2;
camera.position.z = Math.sin( timer ) * 10;
camera.lookAt( scene.position );
particleLight.position.x = Math.sin( timer * 4 ) * 3009;
particleLight.position.y = Math.cos( timer * 5 ) * 4000;
particleLight.position.z = Math.cos( timer * 4 ) * 3009;
renderer.render( scene, camera );
}
}
Your main (?) light position is defined as random like this:
directionalLight.position.x = Math.random() - 0.5;
directionalLight.position.y = Math.random() - 0.5;
directionalLight.position.z = Math.random() - 0.5;
Just use hardcoded, constant position there.
You can use ambient light too, that doesn't need position at all. You can uncomment that from your code, if you want.

I am using three.js to create a scene that has a model on it. I have a plane on which the model sits, and a spotlight shining on the model.
The model is made up of a number of different objects. All of the objects are set to receive and cast shadows. Shadows are being cast on the model itself from other areas of the model.
The plane, however, won't receive shadows. I'm unsure why.
I have adjusted the spotLight.shadowCameraNear and spotLight.shadowCameraFar properties to ensure both the model and plane are within the shadow area. Still nothing.
Below is a screenshot of the model with the spotlight visible.
I have the shadowmap enabled and set to the soft maps:
renderer.shadowMap.enabled = true; // Shadow map enabled
renderer.shadowMap.type = THREE.PCFSoftShadowMap;
My code is as follows:

This was fixed by using a THREE.MeshPhongMaterial instead of a THREE.MeshBasicMaterial.
I just recently started creating a 3D model for a website I am creating.. and for some reason one of the arms of the character is transparent, but only partially as in you can see inside it. As seen here:
Transparent arm and I can't figure it out. I tried back tracking some of my code to no avail, and I tried re rendering it in blender (as it is a .obj import) and it still has the same issue. Does anyone happen to know a fix for the issue?

I'm a bit lost at this point and could really use your help! Thanks in advance. If you have any questions, or not sure about something in my code let me know.
Face normals of the arm might be flipped backside. As you may know, if the face normal is facing backside, it will not be rendered, and only back-side will be rendered, even in 3d modeler too such as blender.
You can check normal direction in three.js using FaceNormalsHelper as well.
Docs for the helper:
http://threejs.org/docs/#Reference/Extras.Helpers/FaceNormalsHelper
http://threejs.org/examples/#webgl_helpers
If normal direction were wrong, flip them in your 3d modeler app.
I made a reflection cube and I am trying to put an animated model inside. But something happen in my function render and I can not see anything.
I am making my first steps using javascript and playing with three.js. If you can help me would be amazing.

}
}

I was supposed to push Mesh into Objects array, but which one?
THREE.SceneUtils.createMultiMaterialObject() creates an object with two child meshes.
So, you need to set the recursive flag to true when calling Raycaster.intersectObjects().
var intersects = ray.intersectObjects( objects, true );

fixed it by making my texture BIGGER (and placing it on the same folder as my model and renaming to the same name as my model)
It seems like ColladaLoader.js does not load small textures for some reason
Another thing there is a bug https://github.com/mrdoob/three.js/issues/3106 but this is the fix https://raw.github.com/jihoonl/three.js/6e5a02427f2b9626a3fccc9c09d8654cc02d2109/examples/js/loaders/ColladaLoader.js , and it seems that it doesnt work without this fix
