These 7 Questions will help you in an AR Developer Interview

-

 


Making your mark in Augmented Reality tech requires strong technical foundation, likely found only in a augmented reality course. With the growing popularity of both AR and VR technologies, their use in retail, marketing, entertainment and even BIM, and Training prove that the technology is the future of interactivity.


Today's world has been revolutionized by technology. Smart devices such as TVs, baby bassinets, self-driving cars, and voice assistants such as Google Home are becoming more common in our everyday lives. Niantic’s (developer) mobile game Pokemon Go took the world by storm and if you’ve played it, you've encountered another branch of this emerging tech - Augmented Reality (AR).


AR is one of the hottest job segments in today's job market due to thriving progress in the field. There are lots of opportunities for people to get on board the AR train now. They get to discover and develop innovative ways to craft solutions for long-standing problems. Preparation is key to landing a job in this popular field.


To help you prepare for your next interview as an AR Developer, here are 7 of the most frequently asked questions.


1. Are There Different Types Of AR?

There are five types of AR: marker-based, markerless, SLAM-based, object recognition, and PC-based.


What is the main difference between markerbased AR and markerless AR?


Marketers and retailers use marker-based AR in their homes for marketing and retail purposes. An example would be an app that enables you to visualize objects virtually in your home before you purchase them.


Devices with markerless AR use their own hardware. The AR software collects information from GPS, camera, and accelerometer.


2. What are the Constraints That Affect A Mobile AR Experience?

Mobile AR experiences are limited by the following technological limitations:

  • Memory

  • Processing power

  • Graphics capability

  • Input and output options

  • Available screen real estate.

 

3. What Is Your Experience With Game Engines? Do You Have Any Preference(S)?

A game engine is a software framework that contains all the necessary tools for creating a game. Building video games requires physics, input-output, and audio-visual interfaces. Game engines serve as the foundation for AR applications.


Unity3D and Unreal are the most commonly used game engines. Download the software and go through the tutorials to familiarize yourself with game engines.


Questions Specific To The Unity Engine:

4. Is There A Difference Between Awake And Start Unity Events?

A Start event is called only when the script component has been enabled. If not, performance will be saved.


When the script instance is loaded only then the Awake function is called.


5. Delta-Time: Why Is It Used?

By using Time.deltaTime, you can find out how long it took the last Read-Only frame to complete (in seconds). As a result, your game is independent of the game frame.


Questions Related To C#:

6. Is There A Difference Between A Class And A Structure?

Structures are value types whose variables contain their data. Stack allocation is used by structures. There are no inheritable elements, and they are all public by default.


A class is a reference type containing a reference to data. Classes can use heap allocation and are inheritable. However, variables and constants are private by default. But all other elements of a class are public.


7. Method Vs. Function: What Is The Difference?

Unity game engine primarily depend on language C#. Understanding the basics of programming is therefore essential.


Functions are snippets of code that are called by a defined name and can have parameters passed to them. A method is a code snippet that is known by a name associated with an object. It works on data that is contained within the class.


Conclusion

The days of playing Minesweeper on your digital platform while living in your real world are long gone. It is all about pushing the boundaries of technology further every year in this era. That is why in Augmented Reality, the real and digital worlds are combined to create a new reality. It's important to be familiar with the various concepts of this field if you're aspiring to make a mark in it.

  V ideo Game Design is not just about a well-written plot and enjoyable gameplay but also requires excellent and engaging character development. Designers and authors create stories and motivations for characters. The character concept artist develops the initial sketches for the characters and adversaries, then the digital art assets that turn into animated things in the game environment created. Innovation is always welcome. Character designers can draw inspiration from the sources as video games get more innovative, bending genres and blending styles. In other words, there is no need for aspiring video game character artists to delay getting started. Today, you may enroll in various Digital Art Courses that will teach you how to create a game design language for your video game concept, sketch them out, and share them on social media or online portfolios.   Importance of Character Design Consider a game in which the main character is absent. Isn't that strange? A ...
