Creating World-Class 3D Animations and Visual Experiences with WebGL, ArcGIS API, Three.js, and D3

WebGL and 3D Animation

Using WebGL, we can create world-class 3D globes and maps with the best performance, precision, visual quality, and usability. It also supports a broad range of browsers, including mobile devices.

The most common approach to 3D is to use flat symbols, such as spheres and cuboids. These perform the best in a web scene.

ArcGIS API for JavaScript

Since its original release, the ArcGIS API for JavaScript has been used to build web mapping applications in dozens of industries. In 2016, Esri released a new version, version 4 (also known as ArcGIS Maps SDK for JavaScript or just JavaScript Maps), with redesigned and modernized capabilities.

The new API offers more dynamic and rich cartographic experiences for users. For example, developers can now use the API’s 3D capabilities to stream in terrain, basemaps, imagery, features and 3D object scene layers. They can also use 3D rendering capabilities such as a color, size or opacity renderer to thematically represent data like population or the width of a tree canopy.

Using the API’s new widget framework, developers can integrate it into their own development frameworks such as Ember or React. The API also supports local builds for deployment in development environments. The API’s classes are grouped into modules with one-to-one relationships. Class information is retrieved by typing all or part of the class name in the search box on this page.


The WebGL API brings 3D graphics to the Internet, allowing websites and applications to use hardware acceleration for better performance. It eliminates the need for specialized plugins, making it a great choice for businesses and developers who want to create immersive visual experiences.

WebGL uses a programming language called GLSL ([Open] GL Shading Language) to control the computer’s Graphic Processing Unit to draw 3D graphics in HTML5 documents using the canvas> element. This API is supported by all major browsers, and it works across operating systems and devices.

One of the biggest advantages of WebGL is its compatibility with a wide range of browsers and platforms. It can be used on desktop computers, laptops, tablets, and smartphones. This is especially useful for companies with global reach who need to support a wide range of users. In addition, the API is easy to integrate into existing web pages and applications. It also provides a way to increase user engagement by providing a more interactive experience.


If you are a developer with some basic Javascript knowledge, you can create incredible 3D animations. ThreeJS is the API that makes this possible, and it takes all the complex stuff out of it for you. All you need to do is add a few simple lines of code.

Objects in the scene are arranged in a tree-like structure. The root of the tree is called the scene, and the render method is passed it along with a camera object. The camera has a set of properties that determine how the objects in the scene are positioned.

The camera’s target property is a Vector3 that represents the direction in which the camera is looking. The target property is copied from the parent camera, so you can use this to set the direction of the child object.


D3 is a high-level JavaScript library and API that lets you render 3D computer graphics in a web browser. It supports a wide variety of data visualization and interaction techniques. It’s a great choice for creating visual info reports, responsive bullet charts, sunburst diagrams, and artworks.

D3 can also be used to create world-class 3D globes and maps with the highest performance, precision, and visual quality. It’s designed for robust interoperability and scales to massive datasets.

Unlike other SVG-based charts, d3 uses the browser’s coordinate system to draw vector shapes on a precise coordinate grid. It has a rich library of functions for creating custom visualizations and animations, such as radial gradients or spherical arcs. It can also be used with jQuery to add dynamic effects and transitions. Its functional style allows code reuse through a collection of official and community-developed modules.

Keyboard Events: Responding to User Input with JavaScript

Keyboard Events in Javascript

Keyboard events are triggered when a physical key is pressed and a character is generated. They are not triggered for non-character keys such as arrow keys and function keys.

The following code uses the keydown event to validate user input in an element with an ID of “input-num”. It displays an error message if any non-numeric characters are typed.

What is a keyboard event?

The keydown, keypress, and keyup events allow you to respond to keyboard input in real time. Each event describes a single interaction between the user and a key (or combination of keys with modifier keys).

The event object contains properties that provide useful information about which key was pressed. For example, the key property returns a character value for the key that was pressed. The code property, on the other hand, represents a physical key on the keyboard without taking into account the keyboard layout, locale, or any modifier keys.

If a user presses an alphabetic, numeric, or punctuation key, then the keypress event fires and triggers functionality. For example, an alert might be displayed. The target of the keypress event shouldn’t be an input element, however; it should be a global window object. This can be accomplished by using the addEventListener() method. The event object will then be passed to any KeyListener or KeyAdapter objects that have registered to receive the event.


The keydown event is fired when a key is pressed down and continues to fire if the key is held down. This event is only triggered for keys that produce a character, so it doesn’t include things like the Ctrl, Shift, and Meta keys.

Keyup occurs when a key is released. This event is similar to keydown, but it is fired only once when a key is released. The keyup event is also not triggered for control keys, which makes it less useful than the keydown event.

Some browsers may allow you to suppress the default action of the keydown event using preventDefault(), but this varies from one browser to another. It is recommended to use this only if you need to. Calling preventDefault() in a handler for the keydown event will cancel the keyboard event on all keys, which could result in the input field not being able to accept any user input. So it’s better to use the keyup event in this case.


Keyup is an event that fires when a keyboard key is released. It occurs once the browser is done executing the default handler for the key down event. This means that calling preventDefault() on the keyup event won’t have any effect.

Keyboard events are used to capture user interaction and trigger functionality based on those actions. They can be triggered by a number of methods, including the html element, event handler function, or addEventListener method.

In the example below, an input text field is logged and a keyboard event is triggered by using the jQuery keyup() method. The event handler function logs a statement showing the type of key that was released. Afterwards, the background color of the input text field is changed to yellow. This is a simple but effective demonstration of how to use the jQuery keyboard events. The same logic could be applied to other html elements, such as links and form input elements.


Keyboard events such as keydown and keyup are often used to capture keyboard input. These events are triggered when a key is pressed down by the user and repeated as long as the key is pressed. However, these events may not work correctly in all browsers. This is because of inconsistencies between the way keyboard events are implemented by different browsers.

The key property of the keyboard event object returns a string that represents the value of the triggering key in a human-readable format. This value includes any modifier keys, such as ‘Shift’ or ‘Ctrl’, that were pressed in addition to the key itself.

In order to use keyboard events in your web application, you must first create a listener function for them. This listener must be attached to an HTML element that can receive focus, such as a input> or textarea>. This listener function must then catch the keyboard events and handle them appropriately.
