Getting Started

Forever Grid, a powerful, responsive, and extremely customizable, versatile grid with image (.jpg, .jpg, .png, .webp) and video (.mp4) support, seamlessly running on all major browsers and mobile devices, including iPhone, iPad, iOS, Android, MAC, and Windows, elevating your website's audio experience to a whole new level.

It is built using EcmaScript6 using the latest JavaScript and CSS standards. The spiral/grid is using Three.js and WebGL shaders running exclusively on the device's GPU, the caption is HTML.

Please note that it will not work locally, it has to run on an HTTP or HTTPS protocol.

It is crucial to optimize your images and videos, especially since they are used as textures. Larger image and video files demand more GPU power to display due to the increased number of pixels. To minimize performance impact, select images and videos that are visually close in size to the grid mesh.

Please note that the mettrix are units so visual aproximation is needed, since the grid runs in 3D space and various aspects like camera position or camera rotation, using pixels is not possible.

Installation

The demo presetes are all included in the build folder.

Choose one of the preset HTML files from the build folder and open it in a text editor as a refference.

In the download files inside the build folder you will find the src folder that contains the JavaScript code and content folder that contains the CSS file and other important files like the vector font, the content folder has to be uploaded on the server where the grid is used.

Include the grid CSS file and JavaScript in the header:

<head>

<!-- ... -->
<link rel="stylesheet" href="./content/global.css">
<script type="text/javascript" src="./src/FWDFG.js"></script>
<!-- ... -->	

</head>

The next step is to add the initialize code in the page header or footer after the inclusion of the grid JavaScript and CSS files.

<script type="text/javascript">
	if(document.readyState == 'complete'){
		setupFG();
	}else{
		document.addEventListener('DOMContentLoaded', ()=>{
			setupFG();
		});
	}

    function setupFG(){

The last step adding the grid is to create a div with an unique ID that will act as the parent/holder for the grid and set the parentId option to point to the div id ex: parentId: 'myDiv', this div can be added anywhere in your page.

<!-- Grid holder. --> 
<div id="myDiv"></div>

To add multiple grids just redo the steps explained above and make sure to change the instance to fwdfg1, fwdfg2, fwdfg3, etc... depending on how many grids are added, also change the parentId to a different ID and if you want add a different grid by also change the gridDataId to point to a different grid.

Please read the settings section to understand the grid configuration options.

Setup grid

A grid is created by adding in the page inside the body a div with an unique ID and setting the display style to none, this will be used only as the grid data markup, This unique ID has to be added as the value of the gridDataId option in the grid settings like this gridDataId: 'gridData'.

<!-- Forever Grid. -->
<div data-src="media/images/1.jpg" data-width="640" data-height="400" data-url="https://fwdapps.net" data-target="_blank">
	<div data-caption="">
		<p class="fwdfg caption">Forever Grid </p>
	</div>
</div> 

<div data-src="media/images/2.jpg" data-width="640" data-height="800" data-url="https://fwdapps.net" data-target="_blank">
	<div data-caption="">
		<p class="fwdfg caption">Infinite Grid </p>
	</div>
</div>

<div data-src="media/images/3.jpg" data-width="640" data-height="427" data-url="https://fwdapps.net" data-target="_blank">
	<div data-caption="">
		<p class="fwdfg caption">Various Sizes </p>
	</div>
</div> 

<!-- Add as many grid items as you need ... -->

</div>

Adding grid items is done by adding inside the grid div one or more div's with data paremeters expplained below.

Grid item parameters

data-src - required media path (.jpg, .jpeg, .png, .webp) or video (.mp4)
data-width - video or image width in px.
data-height - video or image height in px.

Lightbox item parameters

data-rl-src - supported lightbox sources: mp4, mp3, YouTube (use the YouTube video URL), Vimeo (use the Vimeo video URL), HLS, Google Drive and other cloud formats, iframe (use the page URL), HTML content (use the element ID, e.g., #myId), Google Maps (use the Google Maps embed URL), PDF (use a .pdf URL). If you want no action when the item is clicked, set this to none. To open a new page when the center/front item is clicked, set this to the page URL and prefix it with link: (for example, link:https://your-page.com). To open it in the same window, set data-rl-target to _self; to open it in a new page, set it to _blank.
data-rl-poster-src - optional poster. This holds the poster src, the supported formats are .jpg, .jpeg and .png, the poster.
data-rl-subtitle-src - optional subtitle for video. The sbutitle format has to be srt/vtt, a subtitle file example can be found in the media/subtitles folder.
data-rl-vast-src - optional VAST/IMA URL.

Grid item and lightbox caption

To add a thumbnail caption, just add a <div> with a data-caption attribute. For a lightbox caption, add a <div> with a data-rl-caption attribute, as shown above in the template example. The classes can be styled with CSS in the global.css file.

<div data-src="media/images/1.png" data-width="900" data-height="600" data-url="https://fwdapps.net" data-target="_blank">
	<div data-caption="">
		<p class="fwdfg caption">Cute Bunny</p>
	</div>
</div>

	clearInterval(fwdfgAPI);

	// Register the LIKE event.
	fwdfg0.addEventListener(FWDFG.ERROR, onEerror);

Notes

From my very first “Hello, world!” script in the early 2000s, I’ve been driven by one goal: to turn static pixels into living, breathing experiences. Over two decades of relentless tinkering—mastering Three.js for real-time 3D, crafting custom GLSL shaders, and fine-tuning GPU optimizations—has culminated in Forever Grid. Today, it seamlessly transforms your images and videos into interactive, high-performance canvases on any device.

For me this is more than a job, it is my passion, I love to create innovative tools that my clients can benefit from. @Tibi - FWD.
