I'm working with the three.js ocean scene and 3D canvas text. The 3D text is suppose to replace the location of the ball, but the text doesn't appear.
When I inspect elements, I only notice the canvas for the background rendering. How can both canvases- the background and 3D text- appear? How can I overlay a canvas on another?
What is another way to have 3D text over the water without using canvas or canvasrenderer.js for the 3D text?

The first thing i notice is that you are calling the init(); animate(); functions before the loader has a chance to load the font ( and because of that you are not passing the font into the init function like the canvas_geometry_text example ).
I've pasted the code from the ocean example below ( with comments for how I modified it to work with the code from the canvas_geometry_text example ). I've tested this and it works

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?

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

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.
var scene, camera, cameraCube, renderer;
var light1, light2;
var wallMesh;
var init = function(){
// scene
scene = new THREE.Scene();
// cameras
camera = new THREE.PerspectiveCamera( 60, window.innerWidth / window.innerHeight, 1, 100000 );
camera.position.set(0,50000,50000);
cameraCube = new THREE.CubeCamera( 60, window.innerWidth / window.innerHeight, 1, 100000 );
cameraCube.renderTarget.minFilter = THREE.LinearMipMapLinearFilter; // mipmap filter
scene.add(cameraCube)
// textureCube just for test
// var path = "http://three.dev/cortana/textures/";
// var format = '.png';
// var urls = [
// path + 'px' + format, path + 'nx' + format,
// path + 'py' + format, path + 'ny' + format,
// path + 'pz' + format, path + 'nz' + format
// ];
// var textureCube = THREE.ImageUtils.loadTextureCube( urls );
var texture = THREE.ImageUtils.loadTexture( 'http://three.dev/various/textures/white.png' );
// room
var plane = new THREE.PlaneBufferGeometry( 50000, 50000 );
var wallMaterial = new THREE.MeshLambertMaterial( {
color: 0x333333,
ambient: 0xdddddd,
map: texture,
envMap: cameraCube.renderTarget,
combine: THREE.MixOperation,
reflectivity: 0.5
} );
var wallMaterial = new THREE.MeshBasicMaterial({
envMap: cameraCube.renderTarget,
})
wallMesh = new THREE.Mesh( plane, wallMaterial );
wallMesh.rotateX(toRadians(-90));
wallMesh.position.set(0,-250,0);
scene.add( wallMesh );
// sphere
var sphereGeometry = new THREE.SphereGeometry( 100, 64, 64 );
var sphereMaterial = new THREE.MeshPhongMaterial( { ambient: 0x111111, color: 0x111111, specular: 0x333333, shininess: 50, shading: THREE.SmoothShading });
var sphere = new THREE.Mesh( sphereGeometry, sphereMaterial );
sphere.scale.x = sphere.scale.y = sphere.scale.z = 20;
sphere.position.set( 0, 2000, 0 );
scene.add(sphere);
// lights
var ambient = new THREE.AmbientLight(0xffffff);
scene.add( ambient );
var directionalLight1 = new THREE.DirectionalLight( 0xffffff, 1 );
directionalLight1.position.set( 0, 50000, 0 ).normalize();
scene.add( directionalLight1 );
var color = new THREE.Color("rgb(0,255,0)");
light2 = new THREE.PointLight(color, 1, 50000);
light2.position.set(2000,500,2000);
scene.add( light2 );
// renderer
renderer = new THREE.WebGLRenderer({ antialias: true, alpha: true });
renderer.setClearColor( 0xffffff, 1 );
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.autoClear = false;
document.getElementsByTagName('body')[0].appendChild( renderer.domElement );
// controls
controls = new THREE.OrbitControls( camera, renderer.domElement );
controls.rotateSpeed = 0.5;
controls.minDistance = 1000;
controls.maxDistance = 50000;
controls.minPolarAngle = 0;
controls.maxPolarAngle = toRadians(90)
// Events
window.addEventListener( 'resize', onWindowResize, false );
}
function onWindowResize() {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
cameraCube.aspect = window.innerWidth / window.innerHeight;
cameraCube.updateProjectionMatrix();
renderer.setSize( window.innerWidth, window.innerHeight );
}
function animate() {
requestAnimationFrame( animate );
render();
}
function render() {
controls.update();
//camera.lookAt( scene.position );
//cameraCube.rotation.copy( camera.rotation );
//renderer.render( scene, cameraCube );
wallMesh.visible = false;
cameraCube.updateCubeMap(renderer, scene);
wallMesh.visible = true;
renderer.render( scene, camera );
}
window.onload = function(){
init();
animate();
}
I modified an example from Three.js library and I tried to add click event on objects.
After a lot of attempts... I'm still not capable to listening for clicks.
This code produces convex forms.
There is my code:
if ( ! Detector.webgl ) Detector.addGetWebGLMessage();
var container, stats;
var camera, scene, renderer;
var objects = [];
init();
animate();
function init() {
container = document.createElement( 'div' );
document.body.appendChild( container );
camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 2000 );
camera.position.y = 400;
scene = new THREE.Scene();
var light, object, object2, materials;
scene.add( new THREE.AmbientLight( 0x404040 ) );
light = new THREE.DirectionalLight( 0xffffff );
light.position.set( 0, 1, 0 );
scene.add( light );
var map = THREE.ImageUtils.loadTexture( 'textures/ash_uvgrid01.jpg' );
map.wrapS = map.wrapT = THREE.RepeatWrapping;
map.anisotropy = 16;
materials = [
new THREE.MeshLambertMaterial( { ambient: 0xbbbbbb, map: map } ),
new THREE.MeshBasicMaterial( { color: 0x242424, wireframe: true, transparent: false, opacity: 0.1 } )
];
// random convex
points = [];
for ( var i = 0; i < 15; i ++ ) {
points.push( randomPointInSphere( 50 ) );
}
object = THREE.SceneUtils.createMultiMaterialObject( new THREE.ConvexGeometry( points ), materials );
object.position.set( -250, 0, 200 );
scene.add( object );
objects.push( object );
object.callback = function() { console.log('blabla');}
renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setSize( window.innerWidth, window.innerHeight );
container.appendChild( renderer.domElement );
stats = new Stats();
stats.domElement.style.position = 'absolute';
stats.domElement.style.top = '0px';
container.appendChild( stats.domElement );
window.addEventListener( 'resize', onWindowResize, false );
}
function onWindowResize() {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize( window.innerWidth, window.innerHeight );
}
function randomPointInSphere( radius ) {
return new THREE.Vector3(
( Math.random() - 0.5 ) * 1 * radius,
( Math.random() - 0.5 ) * 1 * radius,
( Math.random() - 0.5 ) * 1 * radius
);
}
function animate() {
requestAnimationFrame( animate );
render();
stats.update();
}
function render() {
var timer = Date.now() * 0.0001;
camera.position.x = Math.cos( timer ) * 800;
camera.position.z = Math.sin( timer ) * 800;
camera.lookAt( scene.position );
for ( var i = 0, l = scene.children.length; i < l; i ++ ) {
var object = scene.children[ i ];
object.rotation.x = timer * 5;
object.rotation.y = timer * 2.5;
}
renderer.render( scene, camera );
}
function addMeteor()
{
var map = THREE.ImageUtils.loadTexture( 'textures/ash_uvgrid01.jpg' );
map.wrapS = map.wrapT = THREE.RepeatWrapping;
map.anisotropy = 16;
var materials = [
new THREE.MeshLambertMaterial( { ambient: 0xbbbbbb, map: map } ),
new THREE.MeshBasicMaterial( { color: 0x242424, wireframe: true, transparent: false, opacity: 0.1 } )
];
objects.push( materials );
var object3;
var points3 = [];
for ( var i = 0; i < 10; i ++ ) {
points3.push( randomPointInSphere( 50 ) );
}
object3 = THREE.SceneUtils.createMultiMaterialObject( new THREE.ConvexGeometry( points3 ), materials );
object3.position.set( -50, Math.floor((Math.random()*window.innerWidth)), Math.floor((Math.random()* window.innerHeight)) );
scene.add( object3 );
objects.push( object3 );
}
projector = new THREE.Projector();
// listeners
document.addEventListener( 'mousedown', onDocumentMouseDown, false)
// keyboard handler
function onDocumentMouseDown( event ) {
event.preventDefault();
console.log('blabla');
var vector = new THREE.Vector3(
( event.clientX / window.innerWidth ) * 2 - 1,
- ( event.clientY / window.innerHeight ) * 2 + 1,
0.5 );
projector.unprojectVector( vector, camera );
var ray = new THREE.Raycaster( camera.position, vector.sub( camera.position ).normalize() );
console.log(objects);
var intersects = ray.intersectObjects( objects );
console.log(intersects);
if ( intersects.length > 0 ) {
intersects[0].object.callback();
console.log('blabla');
}
}
renderer.render( scene, camera );
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 );
