Try everything in your space - WebXR
Today’s websites are designed first for mobile and then for other platforms, and it is getting important to bring mobile XR functionality into the websites. Google’s scene viewer is bringing WebXR for mass adoption. Theoretically any 3D model can be tried in your space, and you can easily built AR experience for your website.
eCommerce has already transformed into mCommerse, and now taking steps into xCommerse (XR Commerce). 3D Model viewer is very common requirement for across different domains, and it will be the basic requirement of developing for Metaverse as well as for any digital business in future.

A new form of WebXR
Accessing native XR features from the device using a web page is another form of WebXR.
In this article, I want to share an experiment where I tried to control the android device’s native features such as controlling volume and camera torch from a web page. This use case can be really useful in the XR world, where I can control the feature access in the device from cloud services, even the whole look and feel for showing the device controls can be managed from a hosted web page.

User Account Management In XR
In the previous article, we described the importance of interoperability in while building Enterprise XR solutions, In the article, we will discuss how to manage user accounts in the XR device, and implement single sign-on across the XR apps. We will use Android’s AccountManger approach to login into active directory and integrated it into Unity. Please read my earlier article on setting up the app in active directory, log in using android webview, considering a web-based company login form should appear for login, and no custom login form is allowed to capture the credentials.

WebXR - the new Web
The web has grown from a read-only web (Web 1.0) to interactive web (Web 2.0) and then moved into the semantic web which is more connected and more immersive. 3D content on the web is there for quite some time, the most web-browsers support rendering 3D content natively. The rise for XR technologies and advancements in devices and the internet is leading the demand for Web-based XR. It will be a norm for web-based development.

Enterprise XR - Interoperability
In the previous article, we discussed implementing multi-factor authentication for an andorid application, and in the article we will cover another enterprise aspect, Interoperability.
Interoperability is key aspect when we build enterprise solutions using XR technologies. The enterprises have digital assets in form of mobile apps, libraries, system APIs, and they can’t just throw away these existing investments, in fact, the XR apps must be implemented in such a way that it is interoperable with them seamlessly.

Enterprise XR - Multi-Factor Authentication
XR use cases are growing with advancements in the devices, internet and development technologies. There is an ever-growing demand to build enterprise use cases using ARVR technology. Most enterprise use cases eventually require integration with an enterprise ecosystem such as IAM (Identity and Access Management), ERP, CRM, and single sign-on with other systems.
Most organizations protect digital assets with a single sign-on using Multiple Factor Authentication (MFA). The MFA is generally a web-browser based authentication where the browser redirects to tenant’s authentication page where the user provides their credentials and then the user confirms another factor (PIN, OTP, SMS or mobile notifications), once it succeeds, it gets redirected back to the protected resource.

Static Code Analysis for Unity3D — Part 2
This article is in continuation of Static Code Analysis for Unity3D — Part 1 where we talked about setting up a local sonar server, sonar scanner and running the analysis for a Unity3D project.
It this article, we will discuss setting up the Static Code Analysis with SonarCube in IDE — Rider. We are using Rider as the “External Script Editor” in Unity. Configure Rider here in Unity> Preferences > External Tools > External Script Editor.

Static Code Analysis for Unity3D — Part 1
Static code analysis is a standard practice in software development. There are code scanner tools, which scans the code to find vulnerabilities. There are some nice tools for visualizing and managing code quality. One of the most used tool is SonarQube, supports 25+ languages and flexible configurations of the rules.
There are not enough resources talking about static code analysis for Unity3D. This post covers steps to configure SonarQube and use it for scanning Unity projects.

Exploring AndroidThings IoT
Android Things, an android based embedded operating system, is the new “it” thing in the Internet of Things(IOT) space. Developed by Google under the codename “Brillo, a.k.a. Project Brillo”, it takes the usual Android development stack—Android Studio, the official SDK, and Google Play Services—and applies it to the IOT.
Google formally took the veils off of Brillo at its I/O 2015 conference. It is aimed to be used with low-power and memory constrained IOT devices, allowing the developers to build a smart device using Android APIs and Google Services.

Introduction to Java Lambda Expression
After Java 8, developers can apply functional programming constructs in a pure Object-Oriented programming language through lambda expressions. Using lambda expression sequential and parallel execution can be achieved by passing behavior into methods. In Java world lambdas can be thought of as an anonymous method with a more compact syntax. Here compact means it is not mandatory to specify access modifiers, return type and parameter types while defining the expression.

Introduction to Java Stream API
Prior to JDK 8, collections can only be managed through iterators with the use of for, foreach or while loops. It means that we instruct a computer to execute the algorithm steps.
int sum(List<Integer> list) { Iterator<Integer> intIterator = list.iterator(); int sum = 0; while (intIterator.hasNext()) { int number = intIterator.next(); if (number > 5) { sum += number; } } return sum; } The above approach has the following tailbacks:
