+         (a.ddayZ <= b.fellayZ && a.fellayZ >= b.ddayZ);
+ +

Bounding spheres

+ +

Using bounding spheres to detect collisions is a bit more complex than AABB, but still fairly quick to test. The main advantage of spheres is that they are invariant to rotation, so if the wrapped entity rotates, the bounding sphere would still be the same. Their main disadvantage is that unless the entity they are wrapping is actually spherical, the wrapping is usually not a good fit (i.e. wrapping a person with a bounding sphere will cause a lot of false positives, whereas a AABB would be a better match).

+ +

Point versus sphere

+ +

To check whether an sphere contains a point we need to calculate the distance between the point and the sphere's center. If this distance is smaller than or equal to the radius of the sphere, the point is inside it.

+ +

+ +

Taking into account that the euclidean distance between two points A and B is (Ax-Bx)2)+(Ay-By)2+(Az-Bz)\sqrt{(A_x - B_x) ^ 2) + (A_y - B_y)^2 + (A_z - B_z)} , our formula for point versus sphere collision detection would work out like so:

+ +

f(P,S)=Sradius>=(Px-Sx)2+(Py-Sy)2+(Pz-Sz)2f(P,S) = S_{radius} >= \sqrt{(P_x - S_x)^2 + (P_y - S_y)^2 + (P_z - S_z)^2}

+ +

Or in JavaScript:

+ +
function isPointInsideSphere(point, sphere) {
+  // we are using multiplications because is faster than calling Math.pow
+  var distance = Math.sqrt((point.x - sphere.x) * (point.x - sphere.x) +
+                           (point.y - sphere.y) * (point.y - sphere.y) +
+                           (point.z - sphere.z) * (point.z - sphere.z));
+  return distance < sphere.radius;
+}
+
+ +
+

The code above features a square root, which can be expensive to calculate. An easy optimization to avoid it consists of squaring the radius, so the optimized equation would instead involve distance < sphere.radius * sphere.radius.

+
+ +

Sphere versus sphere

+ +

The sphere vs sphere test is similar to the point vs sphere test. What we need to test here is that the distance between the sphere's centers is less than or equal to the sum of their radii.

+ +

+ +

Mathematically, this looks like so:

+ +

f(A,B)=(Ax-Bx)2+(Ay-By)2+(Az-Bz)2<=Aradius+Bradiusf(A,B) = \sqrt{(A_x - B_x)^2 + (A_y - B_y)^2 + (A_z - B_z)^2} <= A_{radius} + B_{radius}

+ +

Or in JavaScript:

+ +
function intersect(sphere, other) {
+  // we are using multiplications because it's faster than calling Math.pow
+  var distance = Math.sqrt((sphere.x - other.x) * (sphere.x - other.x) +
+                           (sphere.y - other.y) * (sphere.y - other.y) +
+                           (sphere.z - other.z) * (sphere.z - other.z));
+  return distance < (sphere.radius + other.radius); }
+}
+ +

Sphere versus AABB

+ +

Testing whether a sphere and an AABB are colliding is slightly more complicated, but still simple and fast. A logical approach would be to check every vertex of the AABB, doing a point vs sphere test for each one. This is overkill however — testing all the vertices is unnecessary, as we can get away with just calculating the distance between the AABB's closest point (not necessarily a vertex) and the sphere's center, seeing if it is less than or equal to the sphere's radius. We can get this value by clamping the sphere's center to the AABB's limits.

+ +

+ +

In JavaScript, we'd do this test like so:

+ +
function intersect(sphere, box) {
+  // get box closest point to sphere center by clamping
+  var x = Math.max(box.minX, Math.min(sphere.x, box.maxX);
+  var y = Math.max(box.minY, Math.min(sphere.y, box.maxY);
+  var z = Math.max(box.minZ, Math.min(sphere.z, box.maxZ);
+
+  // this is the same as isPointInsideSphere
+  var distance = Math.sqrt((x - sphere.x) * (x - sphere.x) +
+                           (y - sphere.y) * (y - sphere.y) +
+                           (z - sphere.z) * (z - sphere.z));
+
+  return distance < sphere.radius;
+}
+
+
+ +

Using a physics engine

+ +

3D physics engines provide collision detection algorithms, most of them based on bounding volumes as well. The way a physics engine works is by creating a physical body, usually attached to a visual representation of it. This body has properties such as velocity, position, rotation, torque, etc., and also a physical shape. This shape is the one that is considered in the collision detection calculations.

+ +

We have prepared a live collision detection demo (with source code) that you can take a look at to see such techniques in action — this uses the open-source 3D physics engine cannon.js.

Fragment processing focuses on textures and lighting — it calculates final colors based on the given parameters.

+ +

Fragment processing

+ +

Tasuddest

+ +

Textures are 2D images used in the 3D space to make the objects look better and more realistic. Textures are combined from single texture elements called texels the same way picture elements are combined from pixels. Applying textures onto objects during the fragment processing stage of the rendering pipeline allows us to adjust it by wrapping and filtering it if necessary.

+ +

Texture wrapping allows us to repeat the 2D image around the 3D object. Texture filtering is applied when the original resolution or the texture image is different from the displayed fragment — it will be minified or magnified accordingly.

+ +

Tafat

+ +

The colors we see on the screen is a result of the light source interacting with the surface colors of the object's material. Light might be absorbed or reflected. The standard Phong Lighting Model implemented in WebGL has four basic types of lighting:

+ + + +

Azday n tufɣa

+ +

During the output manipulation stage all the fragments of the primitives from the 3D space are transformed into a 2D grid of pixels that are then printed out on the screen display.

+ +

Output merging

+ +

During output merging some processing is also applied to ignore information that is not needed — for example the parameters of objects that are outside of the screen or behind other objects, and thus not visible, are not calculated.

+ + + +

+ +

Now you know the basic theory behind 3D manipulation. If you want to move on to practice and see some demos in action, follow up with the tutorials below:

For rich gaming experiences on the Web the weapon of choice is WebGL, which is rendered on HTML {{htmlelement("canvas")}}. WebGL is basically an OpenGL ES 2.0 for the Web — it's a JavaScript API providing tools to build rich interactive animations and of course also games. You can generate and render dynamic 3D graphics with JavaScript that is hardware accelerated.

+ +

Documentation and browser support

+ +

The WebGL project documentation and specification is maintained by the Khronos Group, not the W3C as with most of the Web APIs. Support on modern browsers is very good, even on mobile, so you don't have to worry about that too much. The main browsers are all supporting WebGL and all you need to focus on is optimizing the performance on the devices you use.

+ +

There's an ongoing effort on releasing WebGL 2.0 (based on OpenGL ES 3.0) in the near future, which will bring many improvements and will help developers build games for the modern Web using current, powerful hardware.

+ +

Explaining basic 3D theory

+ +

The basics of 3D theory centers around shapes represented in a 3D space, with a coordinate system being used to calculate their positions. See our Explaining basic 3D theory article for all the information you need.

+ +

Advanced concepts

+ +

You can do a lot more with WebGL. There are some advanced concepts which you should dive into and learn more about — like shaders, collision detection, or the latest hot topic — virtual reality on the web.

+ +

Shaders

+ +

It's worth mentioning shaders, which are a separate story on their own. Shaders use GLSL, a special OpenGL Shading Language with syntax similar to C that is executed directly by the graphics pipeline. They can be split into Vertex Shaders and Fragment Shaders (or Pixel Shaders) — the former transforms shape positions to real 3D drawing coordinates, while the latter computes rendering colors and other attributes. You should definitely check out GLSL Shaders article to learn more about them.

+ +

Collision Detection

+ +

It's hard to imagine a game without the collision detection — we always need to work out when something is hitting something else. We have information available for your to learn from:

+ + + +

WebVR

+ +

The concept of virtual reality is not new, but it's storming onto the web thanks to hardware advancements such as the Oculus Rift, and the (currently experimental) WebVR API for capturing information form VR hardware and making it available for use in JavaScript applications. For more, read WebVR — Virtual Reality for the Web.

+ +

There's also the Building up a basic demo with A-Frame article showing you how easy it is to build 3D environments for virtual reality using the A-Frame framework.

+ +

The rise of libraries and frameworks

+ +

Coding raw WebGL is fairly complex, but you'll want to get to grips with it in the long run, as your projects get more advanced (see our WebGL documentation to get started.) For real world projects you'll probably also make use of a framework to speed up development and help you manage the project you're working on. Using a framework for 3D games also helps optimize the performance as a lot is taken care of by the tools you use, so you can focus on building the game itself.

+ +

The most popular JavaScript 3D library is Three.js, a multi-purpose tool that makes common 3D techniques simpler to implement. There are other popular game development libraries and frameworks worth checking too; A-Frame, PlayCanvas and Babylon.js are among the most recognizable ones with rich documentation, online editors and active communities.

+ +

Building up a basic demo with Three.js

+ +

Three.js, as any other library, gives you a huge advantage: instead of writing hundreds of lines of WebGL code to build anything interesting you can use built-in helper functions to do it a lot easier and faster. See the Building up a basic demo with Three.js subpage for the step-by-step process of creating the demo.

+ +

Building up a basic demo with A-Frame

+ +

A-Frame is a web framework for building 3D and VR experiences. Under the hood, it is a three.js framework with a declarative entity-component pattern, meaning we can build scenes with just HTML. See the Building up a basic demo with A-Frame subpage for the step-by-step process of creating the demo.

+ +

Building up a basic demo with Whitestorm.js

+ +

Whitestorm.js is a framework built on the top of Three.js technology. It's main distinction is existance of built-in Physics engine and Plugin system based on NPM. See Building up a basic demo with Whitestorm.js for further reading, tutorials and examples of making basic and even complex apps or games using this framework in pair with Three.js.

+ +

Building up a basic demo with PlayCanvas

+ +

PlayCanvas is a popular 3D WebGL game engine open sourced on GitHub, with an editor available online and good documentation. See the Building up a basic demo with PlayCanvas subpage for high level details, and further articles showing how to create demos using the PlayCanvas library, and the online editor.

+ +

Building up a basic demo with Babylon.js

+ +

Babylon.js is one of the most popular 3D game engines used by developers. As with any other 3D library it provides built-in functions to help you implement common 3D functionality more quickly. See the Building up a basic demo with Babylon.js subpage for the basics of using Babylon.js, including setting up a development environment, structuring the necessary HTML, and writing the JavaScript code.

Other tools

+ +

Both Unity and Unreal can export your game to WebGL with asm.js, so you're free to use their tools and techniques to build games that will be exported to the web.

This page lists essential core techniques for anyone wanting to develop games using open web technologies.

+
+ +
+
Using async scripts for asm.js
+
Especially when creating medium to large-sized games, async scripts are an essential technique to take advantage of, so that your game's JavaScript can be compiled off the main thread and be cached for future game running, resulting in a significant performance improvement for your users. This article explains how.
+
Optimizing startup performance
+
How to make sure your game starts up quickly, smoothly, and without appearing to lock up the user's browser or device.
+
Using WebRTC peer-to-peer data channels
+
In addition to providing support for audio and video communication, WebRTC lets you set up peer-to-peer data channels to exchange text or binary data actively between your players. This article explains what this can do for you, and shows how to use libraries that make this easy.
+
Efficient animation for web games
+
This article covers techniques and advice for creating efficient animation for web games, with a slant towards supporting lower end devices such as mobile phones. We touch on CSS transitions and CSS animations, and JavaScript loops involving {{ domxref("window.requestAnimationFrame") }}.
+
Audio for Web Games
+
Audio is an important part of any game — it adds feedback and atmosphere. Web-based audio is maturing fast, but there are still many browser differences to negotiate. This article provides a detailed guide to implementing audio for web games, looking at what works currently across as wide a range of platforms as possible.

+ +

The following can be useful when developing games based on Web technologies.

+ + + +
+

Note: Not every browser supports every part of HTML5. For example, Canvas isn’t supported out of the box by any Internet Explorer version below 9. However, you can use Explorer Canvas to replicate canvas functionality (but that is not ideal and does not perform as well). WebSockets is supported by IE only in IE 10, and it isn’t supported in the stock browser of Android. But again, you can fake this by using Flash for the sockets, such as with Socket.IO. While supported in the latest versions of every other browser, WebGL in Internet Explorer requires at least version 11.

+
+ +
+
asm.js
+
asm.js is a very limited subset of the JavaScript language, which can be greatly optimized and run in an ahead-of-time (AOT) compiling engine for much faster performance than your typical JavaScript performance. This is, of course, great for games.
+
Emscripten
+
+

An LLVM to JavaScript compiler; with Emscripten, you can compile C++ and other languages that can compile to LLVM bytecode into high-performance JavaScript. This is a great tool for porting applications to the Web! There is a useful Emscripten tutorial available on the wiki. Note that we are aiming to cover Emscripten in its own section of MDN.

As a note on learning paths — starting with pure JavaScript is the best way to get a solid knowledge of web game development. If you are not already familiar with pure JavaScript game development, we'd suggest that you first work through this series' counterpart, 2D breakout game using pure JavaScript.

+ +

After that, you can pick any framework you like and use it for your projects; we've chosen Phaser as it is a good solid framework, with a good support and community available, and a good set of plugins. Frameworks speed up development time and help take care of the boring parts, allowing you to concentrate on the fun stuff. However, frameworks are not always perfect, so if something unexpected happens or you want to write some functionality that the framework doesn't provide, you'll need some pure JavaScript knowledge.

+ +
+

Note: This series of articles can be used as material for hands-on game development workshops. You can also make use of the Gamedev Phaser Content Kit based on this tutorial if you want to give a talk about game development with Phaser.

+
+ +
