Lumiscaphe 3D Viewer

Installation

$ npm i @lumiscaphe/viewer

or

$ yarn add @lumiscaphe/viewer

The basics

Initialize Lumiscaphe Viewer as simply as this:

const container = document.getElementById('viewer');

const viewer = new LumiscapheViewer(container, {
  server: 'https://wr.lumiscaphe.com',
  onInteraction: () => {},
  onLoadStart: () => {},
  onLoadProgress: () => {},
  onLoadEnd: () => {},
  onLoadError: () => {},
});

LumiscapheViewer constructor accept following parameters:

• container : div where viewer will be integrated
• server : WebRender server url
• onInteraction : event sent on user interaction
• onLoadStart : event sent on load start
• onLoadProgress : event sent on load progress
• onLoadEnd : event sent on load end
• onLoadError : event sent on load error

Scene

const scene = [{
  database: 'ee294840-5689-49b0-9edb-527598602df0',
  configuration: 'Bin.Blue/Cabin.Yellow/Style.Design1/Wheels.Red',
  animations: ['LeftDoor'],
}];

viewer.load(scene);

A scene is an array of products defined with:

• database : product 3D model guid string
• configuration : product configuration as a string of concatenated values separated by a slash
• animations : product animations as an array of string

Basic scenes should contain only one product.

Decor

Two ways to drive scene decor.

Integrated

When a 3D model contains integrated decors, it can be change through product configuration. For example: add ENV.STUDIO or ENV.ALPES to product configuration string.

const scene = [{
  database: 'ee294840-5689-49b0-9edb-527598602df0',
  configuration: 'Bin.Blue/Cabin.Yellow/Style.Design1/Wheels.Red/ENV.ALPES',
  animations: ['LeftDoor'],
}];

viewer.load(scene);

External

When a 3D model does not contain integrated decors, it can be added with an external 3D model. For example:

const decorProduct = {
  database: '82c1f7e8-9ae4-4f00-b45c-c857e21a954f',
  translation: { x: 0, y: -0.12, z: 0 },
};

const product = {
  database: 'ee294840-5689-49b0-9edb-527598602df0',
  configuration: 'Bin.Blue/Cabin.Yellow/Style.Design1/Wheels.Red',
  animations: ['LeftDoor'],
};

const scene = [decorProduct, product];

viewer.load(scene);

Decor product is defined with:

• database : decor product 3D model guid string
• translation : decor product 3D position (e.g. decorDeltaAltitude)

Note: decor product should always be the first product in the scene.

View

const view = {
  mode: 'image',
  camera: 'EXTER/1',
  background: 'product',
};

viewer.setView(view);

A view can be defined in the following modes:

Image

• mode : image
• camera : camera path
• background : view background mode (product, transparent, gradient)

VRCube

• mode : vrcube
• camera : camera path
• background : view background mode (product, transparent, gradient)

VRObject - animation

• mode : vrobject
• animation : animation name
• camera : camera path
• frames : number of frames
• loop : whether animation loops or not
• background : view background mode (product, transparent, gradient)

VRObject - bookmark set

• mode : vrobject
• camera : camera group path
• background : view background mode (product, transparent, gradient)

Transition

const transition = {
  fromPosition: 0,
  toPosition: 2,
  animation: {
    name: 'Porte Gauche',
    camera: '/Camera_Ext',
    duration: 1,
    reverse: false,
  },
};

viewer.load(scene, transition);

viewer.setView(view, transition);

A transition can be set when loading a scene or setting a view with:

• fromPosition : go to specific vrobject image at the beginning - optional
• toPosition : go to specific vrobject image at the end - optional
• animation :
  • name: animation name
  • camera: camera path to use for animation
  • duration: animation duration in seconds
  • reverse: whether to reverse animation direction

Encoder

// Default values
const encoder = {
  format: 'jpeg',
  quality: 80,
};

viewer.setEncoder(encoder);

An encoder is defined with:

• format : encoder format (jpeg, png)
• quality : encoder quality (0-100 for jpeg and 0-9 for png)

Parameters

// Default values
const parameters = {
  antialiasing: false,
  superSampling: 2,
};

viewer.setParameters(parameters);

Render parameters are defined with:

• antialiasing : whether software antialiasing is enabled or not
• superSampling : super sampling coefficient 1-4

WebRender is always optimized for the following default values (false, 2). Change this with precaution !
