'Attach text above 3D Object
I'm wondering if it is possible to attach a text above a 3D Object? If so, how would I do it?
So far I'm doing the following below to load a mesh with its material and lastly adding it to a THREE.Object3D(); and adding it to the scene. Works great without any problems. Next step is I want to show a nice text above its this object that is always fixed and can be seen from every angle.
loader.load('assets/' + enemyUrl, function (geometry, materials) {
material = new THREE.MeshFaceMaterial( materials );
model = new THREE.SkinnedMesh( geometry, material );
var mats = model.material.materials;
for (var i = 0,length = mats.length; i < length; i++) {
var m = mats[i];
m.skinning = true;
}
ensureLoop(geometry.animations[0]);
function ensureLoop( tmp ) {
for ( var i = 0; i < tmp.hierarchy.length; i ++ ) {
var bone = tmp.hierarchy[ i ];
var first = bone.keys[ 0 ];
var last = bone.keys[ bone.keys.length - 1 ];
last.pos = first.pos;
last.rot = first.rot;
last.scl = first.scl;
}
}
model.scale.set(2.5,2.5,2.5);
// TODO: Randomize where to put it in the world
yawObject.position.y = spawnPosition.y;
yawObject.position.x = spawnPosition.x;
yawObject.position.z = spawnPosition.z;
yawObject.add(model);
scene.add(yawObject);
});
Something like this:
This is what my game looks like now:

sure its possible. you can create a canvas with text on it, which you use as a texture on a plane that always looks at the camera, you could also do it with a single particle, but im not quite sure how it would work since particle materials have a size parameter. something like:
var name = 'Rovdjuret';
var canvas = document.createElement('canvas');
var ctx = canvas.getContext("2d");
ctx.font="20px Georgia";
ctx.fillText(name,10,50);
var texture = new THREE.Texture(canvas);
texture.needsUpdate = true; //just to make sure it's all up to date.
var label = new THREE.Mesh(new THREE.PlaneGeometry, new THREE.MeshBasicMaterial({map:texture}));
and inside the render/animation loop you make all the labels look at the camera:
label.lookAt(camera.position);
