iTwin Viewer for Desktop

The iTwin Desktop Viewer is a configurable iTwin.js viewer that offers basic configuration out-of-the-box and can be further extended through the use of iTwin.js UI Providers. This package should be used for Electron-based desktop applications. For web applications, use @itwin/web-viewer-react.

Installation

yarn add @itwin/desktop-viewer-react

or

npm install @itwin/desktop-viewer-react

Dependencies

If you are creating a new application and are using React, it is advised that you use create-react-app with @bentley/react-scripts. There is also a predefined template that includes the iTwin Viewer package:

npx create-react-app@latest my-app --scripts-version @bentley/react-scripts --template @itwin/desktop-viewer

React component

import React, { useState, useEffect } from "react";
import { Viewer } from "@itwin/desktop-viewer-react";

export const MyViewerComponent = () => {
  const snapshotPath = "./samples/house_model.bim";

  return (
    <Viewer filePath={snapshotPath} enablePerformanceMonitors={true} />
  );
};

Props

Required

  • enablePerformanceMonitors - Enable reporting of data from timed events in the iTwin Viewer in order to aid in future performance optimizations. These are the metrics that will be collected and logged to the browser's performance timeline:
    • Duration of startup to the initialization of iTwin.js services
    • Duration of startup to the establishment of a connection to the iModel
    • Duration of startup to the creation of a view state for the iModel
    • Duration of startup until the last tile is loaded and rendered for the initial iModel view
Local iModel
  • filePath - path to a local Briefcase or Snapshot to load in the viewer. If provided, it will take precedence over any iTwinId/iModelId that may also be provided
Connected iModel
  • iTwinId - GUID for the iTwin (project, asset, etc.) that contains the iModel that you wish to view
  • iModelId - GUID for the iModel that you wish to view
Blank Connections
  • location - The spatial location for the blank connection.
  • extents - The volume of interest, in meters, centered around location Note that this can't be used in conjunction with the iTwinId or iModelId prop.
