Html 3D Cube Control
For a while I have been experimenting with creating 3D objects in a regular web browser without resorting to plugins such as Flash, Silverlight etc. The Cube shown here is adapted from another 3D website I made earlier.
WebGL enables us to render complex 3D models in a browser. However, here I will be looking at creating a 3D object using the various CSS3 transform commands that can take a regular 2D Html element and project it into 3D space.
The advantage of using 3D transforms on regular Html elements is you can project things like Iframe content, images or any other html element into 3D creating some really neat effects.
Compatibility
As the 3D cube shown here uses CSS3 Matrix Transforms rather than the plain Rotate, Scale, Translate methods used by some other 3D Cubes, it works well in IE11. As well as IE11, it has been tested in Firefox, Chrome, Safari and Mobile Safari for iOS.
Html Source
The important bit here is we include the "Cube.js" file. We also need JQuery, that is included as well.
The Div with the ID my3Dsurface will contain our 3D cube. Notice the data-facewidth="256" attribute. This specifies the size of our cube faces.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Css3 3D Sample</title>
<script src="js/jquery-1.10.2.min.js"></script>
<script src="js/cube.js"></script>
<script src="js/sample.js"></script>
<link rel="stylesheet" href="css/styles.css">
</head>
<body>
<div id="my3Dsurface" class="js3dsurface" data-facewidth="256"></div>
</body>
</html>
Javascript Source
Next we create an instance of Js3DSurface and pass it an array of content that will be displayed on each face of our cube. In this example we are using images and simple html content. You can add more complex html such as Iframes, Video tags etc.
We also add 3 event handlers to enable us to spin the cube using the mouse. When the mouse moves with the left mouse button down, we call adjRot passing it the new X and Y position of the mouse.
var cube;
var mouseisdown = false;
$(document).ready(function () {
var faces = new Array();
faces.push('<img src="images/manic-miner-willy.jpg" />');
faces.push('<img src="images/terminator-t-800-head-design.png" />');
faces.push('<div class=
"plain"><h1>3D Cube!</h1><p>Some pla
in html content to be projected onto the side of the cube! Works
in the latest versions of Chrome, Firefox, IE, Safari, Safari Mobile and other Html5 modern browsers.</div>');
faces.push('<img src="images/sinclair-c5.jpg" />');
faces.push('<img src="images/terminator-t-800-head-design.png" />');
faces.push('<img src="images/sinclair-c5.jpg" />');
cube = new Js3DSurface("my3Dsurface", faces);
cube._backSurface.addEventListener('mousemove', mousemove, false);
document.body.addEventListener('mousedown', mousedown, false);
document.body.addEventListener('mouseup', mouseup, false);
});
function mousedown(e) {
mouseisdown = true;
if (e != null) {
e.stopPropagation();
e.preventDefault();
}
return false;
}
function mouseup(e) {
mouseisdown = false;
if (e != null) {
e.stopPropagation();
e.preventDefault();
}
return false;
}
function mousemove(e) {
if (mouseisdown) {
var _off = $(cube._backSurface).offset();
var x = e.clientX - _off.left;
var y = e.clientY - _off.top;
y += $(window).scrollTop();
adjRot(x, y);
}
}
function adjRot(x, y) {
var w = $(cube._backSurface).width();
var h = $(cube._backSurface).height();
var step = 10;
var ry = (((x - (w / 2)) / w) * step);
var rx = (((y - (h / 2)) / h) * step);
cube._cubes[0]._Torque._Y = ry;
cube._cubes[0]._Torque._X = rx;
}
