Three.js skybox seems broken after rotating camera - javascript

js and I'm trying to create a simple skybox based on this demo. Everything seems ok so far except 1 thing when I rotate my camera (I'm using orbitControls.js) and the z value is not the minimum possible then textures act weird and seem broken.
Source:
var camera, scene, renderer, controls, skybox;
var toRadians = function(deg) {
return deg * Math.PI / 180
}
var toDegrees = function(radians) {
return radians * (180 / Math.PI);
}
var init = function() {
// scene
scene = new THREE.Scene();
scene.fog = new THREE.FogExp2( 0xffffff, 0.00010);
// camera
camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 20000 );
camera.position.z = 5000;
scene.add( camera );
// skydome
var urlPrefix = "http://three.dev/skybox/textures/";
var urls = [urlPrefix + "px.png", urlPrefix + "nx.png",
urlPrefix + "py.png", urlPrefix + "ny.png",
urlPrefix + "pz.png", urlPrefix + "nz.png"];
var textureCube = THREE.ImageUtils.loadTextureCube( urls );
var shader = THREE.ShaderLib[ "cube" ];
shader.uniforms[ "tCube" ].value = textureCube;
var material = new THREE.ShaderMaterial( {
fragmentShader: shader.fragmentShader,
vertexShader: shader.vertexShader,
uniforms: shader.uniforms,
depthWrite: false,
side: THREE.BackSide
} ),
skybox = new THREE.Mesh( new THREE.BoxGeometry( 10000, 10000, 10000 ), material );
scene.add( skybox );
//var texture = THREE.ImageUtils.loadTexture( 'http://three.dev/skybox/textures/wood.jpg')
//var paintMaterial = new THREE.MeshBasicMaterial({map: textureCube})
// var lightAmb = new THREE.AmbientLight(0x333333);
// lightAmb.position.set( 0,0,0 );
// scene.add(lightAmb);
// var directionalLightTop = new THREE.DirectionalLight( 0xffffff, 1 );
// directionalLightTop.position.set( 0, 0, 0 ).normalize();
// scene.add( directionalLightTop );
// var color = new THREE.Color("rgb(255,0,0)");
// var pointLightRed = new THREE.PointLight(color, 1, 8000);
// pointLightRed.position.set( 0, 0, 0);
// camera.add( pointLightRed );
// renderer
renderer = new THREE.WebGLRenderer( {alpha: true, antialias: true} );
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.setClearColor( 0xffffff, 1 );
renderer.autoClear = false;
controls = new THREE.OrbitControls( camera, renderer.domElement );
controls.rotateSpeed = 0.5;
controls.minDistance = 500;
controls.maxDistance = 6000;
document.body.appendChild( renderer.domElement );
window.addEventListener( 'resize', onWindowResize, false );
// start rendering
render();
}
function onWindowResize() {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize( window.innerWidth, window.innerHeight );
render();
}
var update = function() {

var render = function() {

controls.update();
requestAnimationFrame( render );
renderer.render(scene, camera);
}
window.onload = function(){
init();
}

You're adding a skybox in the 'main' scene. A better way to accomplish a skydome would be to create a new scene. this will be the 'background' to your 'main' scene. There's also a discussion about skydomes v.s. skyboxes, simply put, a box saves polys, a dome looks better. in this example i'll be using a dome/sphere.
var renderer = new THREE.WebGLRenderer( {alpha: true, antialias: true} );
var mainScene = new THREE.Scene();
var mainCamera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 20000 );
var skydome = {
scene: new THREE.Scene(),
camera: new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 20000 );
};
skydome.material = new THREE.MeshBasicMaterial({color: 0x0F0F0F}) //the material for the skydome, for sake of lazyness i took a MeshBasicMaterial.
skydome.mesh = new THREE.Mesh(new THREE.SphereGeometry(100, 20, 20), skydome.material);
skydome.scene.add(skydome.mesh);
now, during the render function you adjust only the rotation of the skydome camera, not the position.
var render = function(){
requestAnimationFrame( render );
skydome.camera.quaternion = mainCamera.quaternion;
renderer.render(skydome.scene, skydome.camera); //first render the skydome
renderer.render(mainScene, mainCamera);//then render the rest over the skydome
};
renderer.autoclear = false; //otherwise only the main scene will be rendered.

How to avoid transparency overlap using threejs

I am using threejs to build a map application, and I need to make all building models translucent, but in this case, the transparent buildings will overlap, resulting in a confusing display effect, as shown in the following figure
Overlapping renderings
The effect I hope to achieve is similar to the example on mapboxgl, the nearby buildings can directly block the buildings behind, which is much more refreshing
Expected renderings
How can this be done?

Threejs How to set camera for large scale objects

I am rendering a cityscape using Three.js. When attempting to view the scene I can't seem to get the camera near/far settings correct to render the whole scene. When I increase the camera's far plane - I am able to see the model, but it appears blue (image below) until I zoom into it. Is there a way to see the entire model without having to zoom super close to the scene?

When an object is being clipped out of the camera's focal length, you can use Object3D.scale. AFter adjusting this scaler value the entire building is visible in the camera on load and does not get clipped. You adjust the objects scale during the loading callback.

How to show a cube map reflection on a object without showing the cubemap in the background?

How to show a cube map reflection on a object without showing the cubemap in the background?
I like to receive a reflection on a lever mechanism without showing a cubemap in the background. The background should be with a gradient from blue to white.
So basicially, the cubemap should be only visible on the object.
Thank you very much in advance!

You can add a cubemap reflection to your model by specifying the envMap property of the model's material.
Use a pattern like this one:
var path = "textures/cube/foo/";
var format = '.png';
var urls = [
path + 'px' + format, path + 'nx' + format,
path + 'py' + format, path + 'ny' + format,
path + 'pz' + format, path + 'nz' + format
];
var envMap = THREE.ImageUtils.loadTextureCube( urls, THREE.CubeReflectionMapping, callback ); // callback function is optional
var material = new THREE.MeshPhongMaterial( {
color : 0x999999,
specular : 0x050505,
shininess : 50,
envMap : envMap,
combine : THREE.MixOperation, // or THREE.AddOperation, THREE.MultiplyOperation
reflectivity : 0.5
} );

Three.js reflective plane with cubeCamera & texture

I'm trying to create a simple plane which will combine a texture and a cubeCamera reflection and I'm failing and I'm not sure what to do next?
If I swap the envMap on the plane material to a simple jpg/png texturecube then it will work fine, but this is not what I want.
My goal is to create a glossy reflective plane with a texture that will be replicated to create a room and reflect any 3d meshes inside the room.
Here is what I have so far.
