How do I make the rendering using the following three.js code scale as the browser window scales, i.e. the text becomes smaller as the browser window becomes smaller?
Or, can you suggest an alternative approach? I tried using an iframe (with appropriate styling code to make the iframe scale as the browser window scales) which references a web page with the three.js rendering. That approach worked for desktop browsers but did not work for an iPhone.

There is a typo in your code. innerHieght should be innerHeight. Besides, it's necessary to add the point light to your scene.
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 10;
const renderer = new THREE.WebGLRenderer({
antialias: true
});
renderer.setClearColor("#CCC");
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
const geometry = new THREE.BoxGeometry(1, 1, 1);
const material = new THREE.MeshLambertMaterial({
color: 0xFFCC00
});
const mesh = new THREE.Mesh(geometry, material);
scene.add(mesh);
const light = new THREE.PointLight(0xffffff, 1, 500);
light.position.set(10, 0, 25);
scene.add(light);
renderer.render(scene, camera);

I am new to mapbox.
I need to use the supercluster project of mapbox in order to plot 6 millions of gps in a map.
i tried to use the demo in localhost but i only get an empty map !?

I Solved my issue.
to use the supercluster project you need :
1) download and install : node and npm
2) with npm install supercluster: npm i supercluster
then you will get a folder named node_modules in which you will find supercluster folder under it copy the folder named dist (node_modules>supercluster>dist)
3) download from github the project supercluster here you will get a folder named supercluster-master past in it the folder dist copied in step 2)
Now you can test it by selecting index.html into your browser (supercluster-master>demo>index.html)
if you want to test another JSON or GEOJSON file just:
1) put this file under fixtures folder
(supercluster-master>test>fixtures)
then
2) open worker.js (supercluster-master>demo>worker.js) and change the first variable of the geojson function to point on that file
example :
getJSON('../test/fixtures/myFile.geojson', function (geojson) {
Alternatively
you can use the super-cluster algorithme directley in mapbox gl js mapBox gl js example or with jupyter version;mapbox-jupyter mapbox-jupyter example
Leaflet zooms so now and than too much on clicking a cluster.
A small part of 1 marker is shown on the right and a small part from the other marker is shown on the left side of the map.
My workaround is counting markers in scope and re-adjust the zoomlevel when the counter = 0.
Shouldn't that be in the zoomcalculation of leaflet?
The zoom correction:
mcg.on('clusterclick', function () {
if (markersInScope == 0) {
var zoom = map.getZoom();
map.setZoom(zoom - 1);
}
});
You could try adjusting the zoom to fit the bounds of the mcg and add some padding
mcg.on('clusterclick', function () {
map.fitBounds(mcg.getBounds().pad(0.5));
}
});
If you add the markers to a featureGroup, the bounds for the group will available to you:

I'm attempting to learn extjs 4 and I've been struggling with drag and drop for the past couple of days. I've attempted to build a simple application with a viewport and 1 panel. I've set the panel to be draggable: true and the viewport to be a dropzone. When I try and drag the panel around the viewport it jumps erratically.
This is a short video clip of the behavior:
http://youtu.be/6WRf5j_CAR0
These are my two files:
app.js
Ext.Loader.setConfig({
enabled: true
});
Ext.application({
name: 'CS',
appFolder: 'ccms/app',
autoCreateViewport: true,
controllers: [
// 'TestCreator',
// 'Primary',
// 'Manager'
],
launch: function(){
var viewport = Ext.ComponentQuery.query('viewport');
if(viewport.length > 0)
viewport[0].add([{
xtype: 'panel',
width: 300,
height: 300,
draggable: true
}]);
}
});
Viewport.js
Ext.define('CS.view.Viewport', {
extend: 'Ext.container.Viewport',
// layout: 'fit',
listeners: {
render: function(sender){
console.log(sender);
sender.dropZone = new Ext.dd.DropZone(sender.container, {
getTargetFromEvent: function(e) {
console.log('getTargetFromEvent');
var temp = {
x: e.getX() - this.DDMInstance.deltaX,
y: e.getY() - this.DDMInstance.deltaY
};
console.log(temp);
return temp;
},
// On entry into a target node, highlight that node.
onNodeEnter : function(target, dd, e, data){
// Ext.fly(target).addCls('my-row-highlight-class');
},
// On exit from a target node, unhighlight that node.
onNodeOut : function(target, dd, e, data){
// Ext.fly(target).removeCls('my-row-highlight-class');
},
onNodeOver : function(target, dd, e, data){
return Ext.dd.DropZone.prototype.dropAllowed;
},
onNodeDrop : function(target, dd, e, data){
console.log('onNodeDrop');
data.panel.setPosition(target.x, target.y, true);
return true;
}
});
}
}
})

Can anyone tell me what is going on?
I've tried this with Ext JS 4.07 and the 4.1 Beta, same results
Make sure to Change your Panel to DOM element though Panel is a component
listener: {
render: function (panel) {
var PanelEl = Ext.get(panel.id);
