I plan to add equirectangular (or spherical) panorama support on top of existing 6 cube panorama. I found this library that easily does it by converting equirectangular image to 6 cubes:
https://github.com/spite/THREE.EquirectangularToCubemap
where we can simply use equiToCube.convert( texture, 1024 ):
renderer = new THREE.WebGLRenderer();
var loader = new THREE.TextureLoader();
loader.load( 'equirectangular-panorama.jpg', function( res ) {
var equiToCube = new EquirectangularToCubemap( renderer );
mesh = new THREE.Mesh(
new THREE.TorusKnotGeometry( 10, 3, 100, 32 ),
new THREE.MeshBasicMaterial( { envMap: equiToCube.convert( res, 1024 ) } )
);
scene.add( mesh );
} );
Seems simple. However, my 6 cube method to load images looks like this:
function getTextureCube(path, step, total){
var urls = ["1.jpg","2.jpg","3.jpg","4.jpg","5.jpg","6.jpg"];
var loader = new THREE.CubeTextureLoader();
var maxAnisotropy = renderer.getMaxAnisotropy();
var textureCube = loader.load(urls, function(texture){
texture.minFilter = THREE.NearestFilter;
texture.anisotropy = maxAnisotropy;
texture.wrapS = THREE.RepeatWrapping;
texture.repeat.x = -1;
}, function ( xhr ) {
log( (xhr.loaded / xhr.total * 100) + '% loaded' );
}, function ( xhr ) {
log( 'error loading texture', xhr );
});
return textureCube;
}
And I cannot successfully utilize equiToCube.convert( texture, 1024 ) for conversion which results in black screen instead of panorama.
function getEquirectangularTextureCube(path, step, total){
var loader = new THREE.TextureLoader(); // Note TextureLoader
var maxAnisotropy = renderer.getMaxAnisotropy();
var equiToCube = new EquirectangularToCubemap( renderer );
var textureCube = loader.load(path, function(texture){
texture.minFilter = THREE.NearestFilter;
texture.anisotropy = maxAnisotropy;
texture.wrapS = THREE.RepeatWrapping;
texture.repeat.x = -1;
}, function ( xhr ) {
log( (xhr.loaded / xhr.total * 100) + '% loaded' );
}, function ( xhr ) {
log( 'error loading texture', xhr );
});
return equiToCube.convert( textureCube, 2048 ); // Note .convert
}
A few thoughts to help: this returned texture is used in fragment shader and uniforms if that helps with answer. Also, I may be using equiToCube incorrectly - I did using it inside loader.load but unsuccessfully.
Any ideas how to integrate equirectangular (or spherical) panorama support will be appreciated.

I am new to three.js, and i am trying to use raycasting, i am quite confused with how raycasting would work on imported 3d models. Here i imported an obj model, and when i try to detect whether i touch with the imported 3D model, the funciton is not working as i expect. But when i change it to detect a box object i create with three.js, is working as i expected, can someone help with this problem?

The problem is that the object you get from OBJLoader and assign to your building variable is an instance of THREE.Group. Groups do not have an own geometry or material. They are more or less containers holding other 3D objects (like meshes, point clouds, lines or other groups) and representing them as a logical group.
That means they are never the result of a raycasting evaluation which means if(intersects[0].object.id === building.id) always fails.
I suggest you do this after the loading process which tags your objects:
building.traverse( function( object ) {
object.userData.tag = 'building';
} );
You can then use the tag property in your raycasting routine for detecting the building.
How to multiple textures material use in Three.js?.Here three textures using and one 3D sofa.obj format file. I tried a lot of time. Below my code. What do I mistake in my code?
var loader = new THREE.OBJLoader();
var textureLoader = new THREE.TextureLoader();
threeDTexture = new THREE.ImageUtils.loadTexture( 'models/Sofa/Texturses/paradis_beige.jpg' );
threeDTexture2 = new THREE.ImageUtils.loadTexture( 'models/Sofa/Texturses/1.jpg' );
threeDTexture3 = new THREE.ImageUtils.loadTexture( 'models/Sofa/Texturses/2.jpg' );
loader.load('models/Sofa/sofa.obj', function (object) {
var geo = object.children[0].geometry;
var mats = [threeDTexture, threeDTexture2,threeDTexture3];
objct = new THREE.Mesh(geo, mats);
object.traverse(function (child) {
if (child instanceof THREE.Mesh) {
child.material = objct;
}
});
object.position.x = posX;
object.position.y = 0;
object.position.z = posZ;
var size = new THREE.Box3().setFromObject(object).getSize();
object.scale.set(width/size.x, height/size.y, depth/size.z);
scene1.add(object);
console.log(object);
console.log(size);
console.log(width/size.x, height/size.y, depth/size.z);
},
function ( xhr ) {
returnValue = ( xhr.loaded / xhr.total * 100 ) + '% loaded';
console.log(returnValue);
},
function ( error ) {
console.log( 'An error happened' );
}
);
break
first, the textureLoader declared on line-2 is not in use;
second, belowing mats is not an Material Array, you should new MeshBasicMaterial(...) to wrap a texture, see the document here.
var mats = [threeDTexture, threeDTexture2,threeDTexture3];
objct = new THREE.Mesh(geo, mats); // Mesh will not accept this mats param!
I imported the 3D model that contains .obj .mtl and bunch of jpeg and pngs
trying to load the model with /images like this
But, I'm getting is only a black model like his
I wonder what I have missed as I followed the guidelines for using the two loaders.
here is my code.
//loader
var MTTLoader = new THREE.MTLLoader();
MTTLoader.setPath( '/assets/HotAirBalloonIridesium/' );
MTTLoader.load('Air_Balloon.mtl',(materials) => {
console.log(materials);
materials.preload()
var objLoader = new THREE.OBJLoader();
objLoader.load('/assets/HotAirBalloonIridesium/Air_Balloon.obj', (object) => {
console.log(materials)
objLoader.setMaterials(materials)
scene.add(object);
})
})
I wonder what i'm missing as my asset folder contains all the model files
try loading obj using
var loader = new THREE.OBJLoader( manager );
loader.load( 's_v1.obj', function ( object ) {
object.traverse( function ( child ) {
if ( child instanceof THREE.Mesh )
{
// child.material.map = texture2;
// child.material.specularMap=texture;
// child.material.map=texture;
}
} );
// object.position.x = - 60;
// object.rotation.x = 0; //20* Math.PI / 180;
// object.rotation.z = 0;//20* Math.PI / 180;
object.scale.x = 80;
object.scale.y = 80;
object.scale.z = 80;
obj = object
scene.add( obj );
animate(obj);
} );
okay quick update, there was nothing wrong with the loader but I was using the wrong lighting as Phong Material needed
var hemiLight = new THREE.HemisphereLight(0xffffff, 0xffffff, 0.50);
var dirLight = new THREE.DirectionalLight(0xffffff, 0.50);
to be apparent.
You must call "setMaterials" before load obj.
//loader
var MTTLoader = new THREE.MTLLoader();
MTTLoader.setPath( '/assets/HotAirBalloonIridesium/' );
MTTLoader.load('Air_Balloon.mtl',(materials) => {
console.log(materials);
materials.preload()
var objLoader = new THREE.OBJLoader();
objLoader.setMaterials(materials); // "setMaterials" must before "load"
objLoader.load('/assets/HotAirBalloonIridesium/Air_Balloon.obj', (object) => {
console.log(materials)
scene.add(object);
})
})
I'm trying to update the image asset on a geometry after user interaction, basically loading low res assets to begin with and swapping to high res assets when the user interacts with it.
If I just use standard code like below:
var materials = [
new THREE.MeshPhongMaterial({ map:loader.load('assets/object/0.jpg' ) }),
new THREE.MeshPhongMaterial({ map:loader.load('assets/object/1.jpg' ) }),
new THREE.MeshPhongMaterial({ map:loader.load('assets/object/2.jpg' ) }),
new THREE.MeshPhongMaterial({ map:loader.load('assets/object/3.jpg' ) }),
new THREE.MeshPhongMaterial({ map:loader.load('assets/object/4.jpg' ) }),
new THREE.MeshPhongMaterial({ map:loader.load('assets/object/5.jpg' ) }),
];
target.material.map.needsUpdate = true;
var texture = new THREE.MeshFaceMaterial( materials );
target.material = texture;
The low res assets are cleared from the geometry showing the base colour, the high-res assets take a second to load and then appear on the geometry.
I need to load the assets and then swap them, and from some reading it seems like THREE.LoadingManager() is the way to go, however I'm a bit lost.
So far this is what I have but it's throwing errors....
var textureManager = new THREE.LoadingManager();
textureManager.onProgress = function ( item, loaded, total ) {
console.log(item+' = '+loaded / total * 100) + '%';
};
textureManager.onLoad = function () {
console.log(' loading complete');
var materials = [
new THREE.MeshPhongMaterial({ map:myTextureArray[0] }),
new THREE.MeshPhongMaterial({ map:myTextureArray[1] }),
new THREE.MeshPhongMaterial({ map:myTextureArray[2] }),
new THREE.MeshPhongMaterial({ map:myTextureArray[3] }),
new THREE.MeshPhongMaterial({ map:myTextureArray[4] }),
new THREE.MeshPhongMaterial({ map:myTextureArray[5] })
];
target.children[i].material.materials.map.needsUpdate = true;
var texture = new THREE.MeshFaceMaterial( materials );
target.children[i].material = texture;
};
var textureLoader = new THREE.ImageLoader( textureManager );
myTextureArray = [];
var myTexture = new THREE.Texture();
myTextureArray.push( textureLoader.load( 'assets/objtect1/hires/0.jpg', function ( image ) { myTexture.image = image; } ) );
myTextureArray.push( textureLoader.load( 'assets/objtect1/hires/1.jpg', function ( image ) { myTexture.image = image; } ) );
myTextureArray.push( textureLoader.load( 'assets/objtect1/hires/2.jpg', function ( image ) { myTexture.image = image; } ) );
myTextureArray.push( textureLoader.load( 'assets/objtect1/hires/3.jpg', function ( image ) { myTexture.image = image; } ) );
myTextureArray.push( textureLoader.load( 'assets/objtect1/hires/4.jpg', function ( image ) { myTexture.image = image; } ) );
myTextureArray.push( textureLoader.load( 'assets/objtect1/hires/5.jpg', function ( image ) { myTexture.image = image; } ) );
Any ideas where I might be going wrong?
For the benefit of anyone else, the problem was that I was using the ImageLoader, not TextureLoader.
Replace:
var textureLoader = new THREE.ImageLoader( textureManager );
With
var textureLoader = new THREE.TextureLoader( textureManager );
I am starting with THREE.js, and I am trying to draw a rectangle with a texture on it, lit by a single source of light. I think this is as simple as it gets (HTML omitted for brevity):
function loadScene() {
var world = document.getElementById('world'),
WIDTH = 1200,
HEIGHT = 500,
VIEW_ANGLE = 45,
ASPECT = WIDTH / HEIGHT,
NEAR = 0.1,
FAR = 10000,
renderer = new THREE.WebGLRenderer(),
camera = new THREE.Camera(VIEW_ANGLE, ASPECT, NEAR, FAR),
scene = new THREE.Scene(),
texture = THREE.ImageUtils.loadTexture('crate.gif'),
material = new THREE.MeshBasicMaterial({map: texture}),
// material = new THREE.MeshPhongMaterial({color: 0xCC0000});
geometry = new THREE.PlaneGeometry(100, 100),
mesh = new THREE.Mesh(geometry, material),
pointLight = new THREE.PointLight(0xFFFFFF);
camera.position.z = 200;
renderer.setSize(WIDTH, HEIGHT);
scene.addChild(mesh);
world.appendChild(renderer.domElement);
pointLight.position.x = 50;
pointLight.position.y = 50;
pointLight.position.z = 130;
scene.addLight(pointLight);
renderer.render(scene, camera);
}
The problem is, I cannot see anything. If I change the material and use the commented one, a square appears as I would expect. Note that
The texture is 256x256, so its sides are power of two
The function is actually called when the body is loaded; indeed it works with a different material.
It does not work even if I serve the file from a webserver, so it is not an issue of cross-domain policy not allowing to load the image.
What I am I doing wrong?
By the time the image is loaded, the renderer has already drawn the scene, hence it is too late. The solution is to change
texture = THREE.ImageUtils.loadTexture('crate.gif'),
into
texture = THREE.ImageUtils.loadTexture('crate.gif', {}, function() {
renderer.render(scene);
}),
Andrea solution is absolutely right, I will just write another implementation based on the same idea.
If you took a look at the THREE.ImageUtils.loadTexture() source you will find it uses the javascript Image object. The $(window).load event is fired after all Images are loaded ! so at that event we can render our scene with the textures already loaded...
CoffeeScript
$(document).ready ->
material = new THREE.MeshLambertMaterial(map: THREE.ImageUtils.loadTexture("crate.gif"))
sphere = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material)
$(window).load ->
renderer.render scene, camera
JavaScript
$(document).ready(function() {
material = new THREE.MeshLambertMaterial({ map: THREE.ImageUtils.loadTexture("crate.gif") });
sphere = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material);
$(window).load(function() {
renderer.render(scene, camera);
});
});
Thanks...
In version r75 of three.js, you should use:
var loader = new THREE.TextureLoader();
loader.load('texture.png', function ( texture ) {
var geometry = new THREE.SphereGeometry(1000, 20, 20);
var material = new THREE.MeshBasicMaterial({map: texture, overdraw: 0.5});
var mesh = new THREE.Mesh(geometry, material);
scene.add(mesh);
});
In version r82 of Three.js TextureLoader is the object to use for loading a texture.
Loading one texture (source code, demo)
Extract (test.js):
var scene = new THREE.Scene();
var ratio = window.innerWidth / window.innerHeight;
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight,
0.1, 50);
var renderer = ...
[...]
/**
* Will be called when load completes.
* The argument will be the loaded texture.
*/
var onLoad = function (texture) {
var objGeometry = new THREE.BoxGeometry(20, 20, 20);
var objMaterial = new THREE.MeshPhongMaterial({
map: texture,
shading: THREE.FlatShading
});
var mesh = new THREE.Mesh(objGeometry, objMaterial);
scene.add(mesh);
var render = function () {
requestAnimationFrame(render);
mesh.rotation.x += 0.010;
mesh.rotation.y += 0.010;
renderer.render(scene, camera);
};
render();
}
// Function called when download progresses
var onProgress = function (xhr) {
console.log((xhr.loaded / xhr.total * 100) + '% loaded');
};
// Function called when download errors
var onError = function (xhr) {
console.log('An error happened');
};
var loader = new THREE.TextureLoader();
loader.load('texture.jpg', onLoad, onProgress, onError);
Loading multiple textures (source code, demo)
In this example the textures are loaded inside the constructor of the mesh, multiple texture are loaded using Promises.
Extract (Globe.js):
Create a new container using Object3D for having two meshes in the same container:
var Globe = function (radius, segments) {
THREE.Object3D.call(this);
this.name = "Globe";
var that = this;
// instantiate a loader
var loader = new THREE.TextureLoader();
A map called textures where every object contains the url of a texture file and val for storing the value of a Three.js texture object.
// earth textures
var textures = {
'map': {
url: 'relief.jpg',
val: undefined
},
'bumpMap': {
url: 'elev_bump_4k.jpg',
val: undefined
},
'specularMap': {
url: 'wateretopo.png',
val: undefined
}
};
The array of promises, for each object in the map called textures push a new Promise in the array texturePromises, every Promise will call loader.load. If the value of entry.val is a valid THREE.Texture object, then resolve the promise.
var texturePromises = [], path = './';
for (var key in textures) {
texturePromises.push(new Promise((resolve, reject) => {
var entry = textures[key]
var url = path + entry.url
loader.load(url,
texture => {
entry.val = texture;
if (entry.val instanceof THREE.Texture) resolve(entry);
},
xhr => {
console.log(url + ' ' + (xhr.loaded / xhr.total * 100) +
'% loaded');
},
xhr => {
reject(new Error(xhr +
'An error occurred loading while loading: ' +
entry.url));
}
);
}));
}
Promise.all takes the promise array texturePromises as argument. Doing so makes the browser wait for all the promises to resolve, when they do we can load the geometry and the material.
// load the geometry and the textures
Promise.all(texturePromises).then(loadedTextures => {
var geometry = new THREE.SphereGeometry(radius, segments, segments);
var material = new THREE.MeshPhongMaterial({
map: textures.map.val,
bumpMap: textures.bumpMap.val,
bumpScale: 0.005,
specularMap: textures.specularMap.val,
specular: new THREE.Color('grey')
});
var earth = that.earth = new THREE.Mesh(geometry, material);
that.add(earth);
});
For the cloud sphere only one texture is necessary:
// clouds
loader.load('n_amer_clouds.png', map => {
var geometry = new THREE.SphereGeometry(radius + .05, segments, segments);
var material = new THREE.MeshPhongMaterial({
map: map,
transparent: true
});
var clouds = that.clouds = new THREE.Mesh(geometry, material);
that.add(clouds);
});
}
Globe.prototype = Object.create(THREE.Object3D.prototype);
Globe.prototype.constructor = Globe;
Without Error Handeling
//Load background texture
new THREE.TextureLoader();
loader.load('https://images.pexels.com/photos/1205301/pexels-photo-1205301.jpeg' , function(texture)
{
scene.background = texture;
});
With Error Handling
// Function called when download progresses
var onProgress = function (xhr) {
console.log((xhr.loaded / xhr.total * 100) + '% loaded');
};
// Function called when download errors
var onError = function (error) {
console.log('An error happened'+error);
};
//Function called when load completes.
var onLoad = function (texture) {
var objGeometry = new THREE.BoxGeometry(30, 30, 30);
var objMaterial = new THREE.MeshPhongMaterial({
map: texture,
shading: THREE.FlatShading
});
var boxMesh = new THREE.Mesh(objGeometry, objMaterial);
scene.add(boxMesh);
var render = function () {
requestAnimationFrame(render);
boxMesh.rotation.x += 0.010;
boxMesh.rotation.y += 0.010;
sphereMesh.rotation.y += 0.1;
renderer.render(scene, camera);
};
render();
}
//LOAD TEXTURE and on completion apply it on box
var loader = new THREE.TextureLoader();
loader.load('https://upload.wikimedia.org/wikipedia/commons/thumb/9/97/The_Earth_seen_from_Apollo_17.jpg/1920px-The_Earth_seen_from_Apollo_17.jpg',

Use TextureLoader to load a image as texture and then simply apply that texture to scene background.
new THREE.TextureLoader();
loader.load('https://images.pexels.com/photos/1205301/pexels-photo-1205301.jpeg' , function(texture)
