Example HTML

<div
	class="cloudimage-360"
	data-folder="https://scaleflex.cloudimg.io/v7/demo/360-car/"
	data-filename-x="{index}.jpeg"
>
	<button class="cloudimage-360-left"></button>
	<button class="cloudimage-360-right"></button>
	<button class="cloudimage-360-top"></button>
	<button class="cloudimage-360-bottom"></button>
</div>

Spin in X and Y axes

Allow the view to spin in both X, Y axes

Requirements

We need to provide the file-name of the y-axis images using data-filename-y

Also as we did for the x-axis if we are intializing the view using data-folder and data-filename-y so we need to provide data-amount-y which indicates the number of images on the y-axis. example:

<div
   class="cloudimage-360"
   data-folder="https://scaleflex.cloudimg.io/v7/demo/360-nike/"
   data-filename-x="nike-{index}.jpg"
   data-filename-y="nike-y-{index}.jpg"
   data-amount-x="35"
   data-amount-y="36"
>
</div>

Note: We can initilize the view in x, y axes without providing add data-folder, data-amount-y, data-amount-y. Just we need to provide the data-amount-y

Hotspots or Markers

Display information about the product on specific areas. Once a hotspot is created it can be used on more than one image.

Requirements

First, we need to set data-hotspots attribute to the view we want to add hotspots or markers on it, to prevent the plugin to init the view without hotspots config. Also we need to set an id attribute, we will need it to link the view with the hotspots config.

Create hotspots configuration

The hotspots config should be an array of objects, each object in the array indicates a single hotspot config. For each item in the array, we need to set the positions (X-coord and Y-coord) of the hotspot at every image index we need to show the hotspot on it. hint: To know the current image index we will need to set data-info="white || black" attribute.

example:

const HOTSPOTS_CONFIG = [
 {
  positions: [
   { imageIndex: 0, xCoord: 527, yCoord: 319 },
   { imageIndex: 1, xCoord: 524 },
   { imageIndex: 2, xCoord: 520 },
   { imageIndex: 3, xCoord: 498 },
   { imageIndex: 4, xCoord: 470 },
   { imageIndex: 5, xCoord: 441 },
  ]
 }
]

In the previous example, we have only set the Ycoord a single time at the image index 0. So if the coord didn't change there's no need to reset it, it will already take the previous value.

Now we need to set the hotspot variant, we have three types of hotspots (link, popup, and custom), as it will be explained below.

Variant

Link

we need to provide the URL of the link and the link title.

example:

const HOTSPOTS_CONFIG = [
 {
  positions,
  variant: {
  title: 'New Gurkha Technical Specifications',
  url: 'https://www.forcegurkha.co.in/specifications/',
  newTab: true
  }
 }
]

Popup

Only the property inserted will displayed. | Property |Type | Default | Description | | ------------- | ------------- | ------------- |------------- | | images | Array| [] | To display a carousel of images we need an array of objects, each object should include the src and the alt of each image | | title |String| null | Display title underneath the images | | description| String | null | Display description underneath the title | | moreDetailsUrl | String | null | Display a button underneath the description to navigate to a provided URL | | moreDetailsTitle | String | null| Set the title of the more details button |

example:

const HOTSPOTS_CONFIG = [
 {
  positions,
  variant: {
   images: [
    { src: 'https://scaleflex.cloudimg.io/v7/demo/360-assets/AIR_SNORKEL_FINAL_JPG.png?vh=88bccb', alt: 'air snorkel' }
   ], // optional
   title: 'Air Intake Snorkel', // optional
   description: 'The snorkel gives the Gurkha an unmatched water-wading ability and ensures ample supply of fresh air for combustion.', // optional
   moreDetailsUrl: 'https://forcegurkha.co.in', // optional
   moreDetailsTitle: 'Read more' // optional
  }
 }
]

Custom

Display any element in the DOM in a popup and link it with the hotspot. We will need to set the variant property value to the id of the element.

example:

const HOTSPOTS_CONFIG = [
 {
  positions,
  variant: 'gurkha-suv'
 }
]

PopupProps

Options to customize the hotspot popup.

Properties

| Property | Type | Defaullt |Description | | ------------- | ------------- | ------------- | ------------- | | popupSelector |String| null |Set className to the popup wrapper | | open |Boolean | false |Open the popup | | arrow |Boolean| true |Dipslay an arrow that points toward the hotspot element| | offset|Array | [0, 0] |Set a distance between the hotspot element and the popup | | placement|String| Auto|- we can adjust the position of the hotspot popup relative to the hotspot element. (top - bottom - left - right)|

example:

const HOTSPOTS_CONFIG = [
 {
  positions,
  variant,
  popupProps: {
   popupSelector: 'air-intake-popup', // optional
   offset: [20, 5], // optional
   arrow: false, // optional
   placement: 'bottom' // optional
  },
  indicatorSelector: 'first-hotspot-icon' // optional
 }
]

Responsive hotspots

Now we need to make our hotspots responsive to have an accurate positioning in different screens. we have to set initialDimensions property to every hotspot config. which indicates the dimension of the cloudimage-360 view. hint: data-info can be used to get view size.

example:

const HOTSPOTS_CONFIG = [
 {
   positions,
   variant,
   popupProps,
   indicatorSelector,
   initialDimensions: [ 1170, 662 ]
 }
]

Add Hotspots

we need this function to link the created config with the 360-view.

window.CI360.addHotspots(idOftheView, hotspotsConfig);

example:

window.CI360.addHotspots("gurkha-suv", HOTSPOTS_CONFIG);

data-responsive (or responsive)

Type: String (Cloudimage token) | Default: none | required for cloudimage responsive plugin

Enables cloudimage responsive plugin for 360 view.

Cloudimage Responsive Integration

See how it works (article on Medium)

Requirements

To use the Cloudimage Responsive plugin, you will need a Cloudimage token to deliver your images over CDN. Don't worry, it only takes seconds to get one by registering here. Once your token is created, you can configure it as described below. This token allows you to use 25GB of image cache and 25GB of worldwide CDN traffic per month for free.

data-responsive (or responsive)

Type: String (Cloudimage token) | Default: none | required for cloudimage responsive plugin

Enables cloudimage responsive plugin for 360 view.

data-request-responsive-images (or request-responsive-images)

Type: Bool | Default: false

Request new images on resize, based on the container width.

data-transformation (or transformation)

Type: String | Default: none | optional

Applies Cloudimage resize operations to your image, e.g. width, height, crop, face crop, rotate, prevent enlargement... Multiple transformation operations can be applied to your image, separated by "&" (Ampersand). example:

data-transformation="w=400&h=200&func=fit"

Full documentation here.

data-filters (or filters)

Type: String | Default: none | optional

Applies Cloudimage filters to your image, e.g. brightness, contrast, greyscale, blur, Sharpen... Multiple filters can be applied, separated by "," (comma). example:

data-filters="bright:15,contrast:30"

Full documentation here.

Lazy Loading

Lazy loading is not included into js-cloudimage-360-view by default. There are well thought libraries to achieve that. If you enable lazy loading in the configuration, you need to add an additional library like lazysizes, yall.js (Yet Another Lazy Loader), lozad.js to handle it.

Implementation example with lazysizes

Implementation example with yall.js

Implementation example with lozad.js

Best practices

• In order to use cloudimage responsive with 360 view, your original (master) images should be stored on a server or storage bucket (S3, Google Cloud, Azure Blob...) reachable over HTTP or HTTPS by Cloudimage. If you want to upload your master images to Cloudimage, contact us at [email protected].
