I want to add two functionalities in planetaryJS globe

  1. I wanted to increase Zoom speed for globe created by planetary JS
  2. How can I generate multiple pings like the ones being generated here. I know it needs a set of longitude and latitude but I am unable to do that even for one ping.

Moreover the globe given there is so smooth to rotate than the one provided by planetaryJS

In short I want to implement exactly similar globe like this

Any inputs?

The Kaspersky's globe background is too good. As we rotate globe, the background is moving, how should I implement it? I have tried here

(function() {
  var canvas = document.getElementById('quakeCanvas');

  // Create our Planetary.js planet and set some initial values;
  // we use several custom plugins, defined at the bottom of the file
  var planet = planetaryjs.planet();

colors = ['red', 'yellow', 'white', 'orange', 'green', 'cyan', 'pink'];
            setInterval(function() {
                var lat = Math.random() * 170 - 85;
                var lng = Math.random() * 360 - 180;
                var color = colors[Math.floor(Math.random() * colors.length)];
                var angle = Math.random() * 10;
                planet.plugins.pings.add(lng, lat, { color: color, ttl: 2000, angle: angle });
            }, 250);

Using above code you can create as many as possible pings with different colors.

To increase zoom speed, change line 17 of your fiddle to

planet.loadPlugin(planetaryjs.plugins.zoom({scaleExtent: [500, 10000]}));

by changing the 500 here, you can increase the speed of zooming using the scrollwheel / laptop pinch to zoom

There's an example of how to add random pings to your map here on line 40: http://planetaryjs.com/examples/rotating.html

Like this:

setInterval(function() {
var lat = Math.random() * 170 - 85;
var lng = Math.random() * 360 - 180;
globe.plugins.pings.add(lng, lat, 'white');
}, 150);

It's important to remember that the cybermap by kaspersky is using WebGL, and is not using the planetaryJS library (built on D3.js, which is 2D based). Using WebGL renders the Kaspersky globe much faster, at the expense of a longer development time.

  • the edit in line 17 suggested by you will only change the zoom in and zoom out limit – prashantitis Dec 19 '16 at 07:20
  • It will not make glove smoother anymore.... Btw I know kaspersky uses WebGL....but how to achieve the similar smoothness...is what I requested everyone to answer – prashantitis Dec 19 '16 at 07:21
