VRVIEW React

React Component for virtual tour creation

- It encapsulates Google's Vrview Library
- It is posible to define points (aka hotspots) to navigate between images/videos
- It is posible to assign an arbitrary function to a hotspot click event
- Using a smartphone and Google's Cardboard
or other specialized hardware it is posible to have a full and inmersive virtual reality expereince

## Demo

- DEMO full screen (for mobile)
- DEMO in simulator (for desktop) Warning: Javascript in external iframes might have restrictions
for security reasons. Run the full scren demo to avoid restrictions.
- Note: the demo uses Fabric UI Framework from Microsoft

## Requirements
- Node/npm/yarn
- A project created with Create-React-App for Typescript. If you don't want to use Typescript you must erase all
type information manually.

## Installation

- To install in a existing `Create-React-App` project, run `nmp install --save YagoLopez/vrview-react`
- To copy and run this project:
- Clone or fork this repository
- Install dependencies: `npm install` inside your local directory project
- Run the application: `npm run start`

## Application Programming Interface

```reactjs

```

Vrview is a prure component. It receives scene data as props from a parent component and asign those props to its state which implements the following interface:

```typescript
export interface IScene {
scene: {

// Scene id
id: number | string,

// Scene title
title?: string,

// Scene description
description?: string,

// URL pointing to a 360° video file or an adaptive streaming manifest file (.mpd or .m3u8).
video?: string,

// URL pointing to a 360° image file. Exactly one video or image is required.
// Images and videos must be in /public directory
image?: string,

// Iframe's width attribute.
width?: string | number,

// Iframe's height attribute.
height?: string | number,

// URL to a preview image for a 360º scene (video/image).
preview?: string,

// Indicates whether the content has stereo format or not.
is_stereo?: boolean,

// Turns on/off debug canvas features (like showing the FPS meter).
is_debug?: boolean,

// Enables/disables the VR mode button.
is_vr_off?: boolean,

// Enables/disables the autopan introduction on desktop.
is_autopan_off?: boolean,

// When true, prevents roll and pitch. This is intended for stereo panoramas.
is_yaw_only?: boolean,

// The initial volume of the media; it ranges between 0 and 1; zero equals muted.
volume?: number,

// Enable/disable the loop in the video
loop?: boolean,

// Mutes/unmutes the sound of the video
muted?: boolean,

// Numeric angle in degrees of the initial heading for scene.
default_yaw?: number,

// By default, the camera points at the center of the image.
// When true, the fullscreen button contained inside the VR View iframe will
// be hidden. This parameter is useful if the user wants to use VR View's fullscreen
// workflow (via vrView.setFullscreen() callback) with an element outside the iframe.
hide_fullscreen_button?: boolean
},

// Array of clickable points on scene
hotspots?: Array
}
```

A scene can have zero or more hotspots of type `IHotspot`:

```typescript
export interface IHotspot {

// Hotspot identifier. Used on click event
name: string;

// The latitude of center, specified in degrees, between -90 and 90, with 0 at the horizon.
pitch: number;

// The longitude of center, specified in degrees, between -180 and 180, with 0 at the image center.
yaw: number;

// The radius of the hotspot, specified in meters.
radius: number;

// The distance of the hotspot from camera, specified in meters.
distance: number;

// Destination scene for on click event
idNewScene?: number | string;

// Arbitrary function to run on hotspot click event. (Function call must be string to be valid JSON)
clickFn?: string;

}
```

## Use

- Static assets like images and videos must go in `public` directory
- Copy `public/vrview` folder to your project `public` folder
- Import `Vrview` component from `node_modules/vrview-react/src/vrview`
- Define a scene in json format and pass it to `VrviewCmp` component as props. Each scene follows the interface `IScene`.
For example, for a simple scene:

```javascript
scene: IScene = {
scene: {width: '90%', height: 400, image: '../images/coral.jpg', is_stereo: true, is_debug: true}
}
```

- To create a virtual tour with several scenes you can define an array of scenes. To navigate from one
scene to another define a hotspot and a relation with other scene using "idNewScene" as external key (like in a
relational database). In this demo it has been used the Repository Pattern and a `SceneCollection` Class that loads
and manages the scenes from a `scenes.json` file but this data could be loaded from an external API.

```javascript
[{
"scene":
{
"id": 1,
"width": "100%",
"height": 400,
"image": "../images/coral.jpg",
"is_stereo": true,
"is_debug": true,
"title": "Title Scene 1",
"description": "Initial scene with three hotspots. One hotspot has a new scene associated, other has no new scene and the third executes a function"
},
"hotspots": [
{"name": "scene1-hotspot1", "pitch": 0, "yaw": 0, "radius": 0.05, "distance": 2, "idNewScene": 2},
{"name": "scene1-hotspot2", "pitch": 0, "yaw": -35, "radius": 0.05, "distance": 2},
{"name": "scene1-hotspot3", "pitch": -20, "yaw": -25, "radius": 0.05, "distance": 2,
"clickFn": "alert('Function executed');"}
]
},
{
"scene":
{
"id": 2,
"image": "../images/landscape1.jpg",
"is_stereo": false,
"title": "Title Scene 2",
"description": "Scene 2 has two hotspots with respectives scenes associated"
}
}]
```

- Each time the user clicks a hotspot a new scene is loaded from `ScenesCollection` and passed from `App`
component to `VrviewCmp` as props and `VrviewCmp` set its state from the incoming props with the new scene data.

- Hotspots are optional and you can also define an arbitrary function for a hotspot click event.
For example, in the following case instead of defining a `idNewScene` object just define the `clickFn` property:

```javascript
{
scene: {image: '../images/walrus.jpg', is_stereo: true},
hotspots: [
{name: 'hotspot5', pitch: -20, yaw: -25, radius: 0.05, distance: 2, clickFn: '() => alert("Function executed")'}
]
}
```
