JavaScript Documentation

Documentation for the JavaScript version, API and overall JavaScript implementation.

Getting Started

Flimstrip Carousel, a powerful, responsive, and extremely customizable infinite 3D carousel with image (.jpg, .jpg, .png, .webp) and video (.mp4) support and lightbox support using Revolution Lightbox, 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 carousel is using Three.js and WebGL shaders running exclusively on the device's GPU, the interface like buttons are in 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, especially since they are used as textures. Larger image files demand more GPU power to display due to the increased number of pixels. To minimize performance impact, select images that are visually close in size to the carousel plane width and height. After you have the final images use tinypng to reduce the images size without losing quality, there are other similar tool.

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


Installation

There are a few HTML filse 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 carousel is used.

Include the carousel CSS file and JavaScript in the header:

<head>

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

</head>

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

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

	function setupFSC(){

</script>

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

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

To add multiple carousels just redo the steps explained above and make sure to change the instance to fwdfsc1, fwdfsc2, fwdfsc3, etc... depending on how many carousels are added, also change the parentId to a different ID and if you want add a different carousel gallery by also change the carouselDataId to point to a different carousel gallery.

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


A carousel gallery 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 carousel gallery data markup, This unique ID has to be added as the value of the carouselDataId option in the carousel settings like this carouselDataId: 'carouselData'.

<!-- Carousel data. -->
<div id="carouselData" style="display: none;">

	 <div>
		<div data-src="media/thumbnails/mp4.jpg" data-width="900" data-height="600"></div>
		<li data-rl-src="media/videos/fwd-1080p.mp4" data-rl-poster-src="media/images/mp4.jpg" data-rl-subtitle-src="media/subtitles/english_subtitle.vtt"></li>
		<div data-caption="">
			<p class="caption-title">Lightbox MP4 Self/External Hosted With Subtitle</p>
			<p class="caption-desc">Film Strip Carousel has included <a href="https://webdesign-flash.ro/p/evp" target="_blank">Easy Video Player</a> with amazing features.</p>
		</div>
		<li data-rl-caption="">
			<p class="fwdrl-title">MP4 Self/External Hosted With Subtitle</p>
			<p class="fwdrl-desc">Film Strip Carousel has included <a href="https://webdesign-flash.ro/p/evp" target="_blank">Easy Video Player</a> with amazing features.</p>
		</li>
	</div> 

	<div>
		<div data-src="media/thumbnails/adsense.jpg" data-width="900" data-height="600"></div>
		<li data-rl-src="media/videos/fwd-1080p.mp4" data-rl-poster-src="media/images/adsense.jpg" data-rl-vast-src="//googleads.g.doubleclick.net/pagead/ads?ad_type=video&client=ca-video-pub-4968145218643279&videoad_start_delay=0&description_url=http%3A%2F%2Fwww.google.com&max_ad_duration=40000&adtest=on"></li>
		<div data-caption="">

		</div>
		<li data-rl-caption="">
			<p class="fwdrl-title">Google Adsense & IMA SDK/Interactive Media Ads</p>
			<p class="fwdrl-desc">Google Adsense & IMA SDK/Interactive Media Ads support, <a href='https://webdesign-flash.ro/p/evp' target='_blank'>Easy Video Player</a>.</p>
		</li>
	</div> 

	... etc add as many images as you want ...

</div>

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

Carousel item parameters

  • data-src - required media path (.jpg, .jpeg, .png, .webp, .mp4).
  • data-width - the image native width.
  • data-height - the image native height.

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.

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.

		clearInterval(fwdfscAPI);

		// Register the update event.
		fwdfsc0.addEventListener(FWDFSC.ITEM_UPDATE, onItemUpdate);

}, 100);

// Listen for the CHANGE event.
function onItemUpdate(e){
	//console.log(e)
}

Notes

As a developer, I love building with Film Strip Carousel (FSC). Crafting the curved 3D film-strip effect, fine-tuning animations, and customizing every detail—from spacing and colors to smooth motion—makes the process both creative and technical. Bringing media to life with FSC is one of those projects where code and design truly meet.
