(a) Define: a) Virtual Reality b) Augmented Reality c) Mixed Reality

a) Virtual Reality (VR) refers to a computer-generated environment that simulates a real or imagined environment and allows users to interact with it using specialized hardware and software, such as a VR headset. VR creates an immersive experience that can be used for a variety of applications, including gaming, education, and training.

b) Augmented Reality (AR) refers to the overlay of digital content onto the real world, typically using a camera-equipped device such as a smartphone or a tablet. AR enhances the user’s perception of the real world by adding digital content such as images, text, or animations, and can be used for various applications, including gaming, advertising, and education.

c) Mixed Reality (MR) is a combination of VR and AR, which allows users to interact with both digital and real-world objects simultaneously. MR creates a virtual environment that is anchored in the real world and enables users to interact with virtual objects as if they were real. This technology is commonly used in areas such as gaming, education, and healthcare.

(b) Explain the Primary Features and Present Development on Virtual

(c) Explain the various components of virtual reality systems with block

(a) Explain Virtuality and Immersion.

Virtuality refers to the extent to which a VR experience replicates the characteristics of the real world. In other words, it describes how closely the virtual environment resembles the physical environment in terms of its visual, auditory, and other sensory cues. The higher the level of virtuality, the more closely the virtual environment resembles the real world.

Immersion refers to the extent to which a user feels like they are a part of the virtual environment. It is the degree to which the user is psychologically and emotionally engaged in the VR experience. High levels of immersion are characterized by a sense of presence, where the user feels like they are actually present in the virtual environment.

Virtuality and immersion are closely related because the degree of virtuality of a VR experience directly affects the level of immersion that the user can achieve. A highly realistic and detailed virtual environment can increase the level of immersion by making the experience more engaging and believable. Similarly, a lower level of virtuality can reduce the level of immersion by making the experience less realistic and less engaging.

(b) Define computer graphics and also discuss rendering process.

(c) What is projection? Explain in detail with its type.

(c) What is reflection? Explain its models in detail.

(a) Explain 3 ‘I’ of virtual reality.

The 3 ‘I’s of Virtual Reality are:

  1. Immersion: Immersion refers to the degree to which the user feels fully engaged in the virtual environment. The immersive experience is created by providing a sense of presence, where the user feels as though they are part of the virtual environment. This can be achieved through high-quality graphics, sound, and interactive elements that respond to the user’s movements and actions.
  2. Interaction: Interaction is the ability of the user to engage with the virtual environment and the objects within it. In virtual reality, interaction is typically achieved through the use of motion controllers, haptic feedback, and other sensory devices that provide a sense of touch and presence. Interaction can help to enhance immersion and make the virtual experience more engaging and enjoyable for the user.
  3. Imagination: Imagination refers to the ability of virtual reality to transport users to new and exciting worlds, providing a sense of wonder and exploration. Virtual reality can enable users to experience things that may not be possible in the real world, such as exploring other planets, visiting historical landmarks, or interacting with fantastical creatures. Imagination is a key component of virtual reality, as it allows users to expand their horizons and experience things that would otherwise be impossible.

(b) Write short note on display technologies of Augmented Reality with

(c) List and explain the various challenges with Augmented Reality.


(a) What is Linear and Nonlinear interpolation?

Interpolation refers to the process of estimating values of a function for any given point within the range of known values. It is commonly used in computer graphics to create smooth transitions between points, such as when creating animations.

Linear interpolation is the simplest form of interpolation. It works by drawing a straight line between two points and estimating the value of a point along that line. For example, if you have two points A and B, with values 2 and 5 respectively, and you want to know the value at point C, which is halfway between A and B, then linear interpolation will estimate the value of C to be 3.5.

Nonlinear interpolation is a more complex form of interpolation that uses mathematical functions to estimate values between known points. It is used when the relationship between points is more complex than a straight line. For example, if you have a set of data points that form a curve, then nonlinear interpolation can be used to estimate values between those points.

(b) Explain 2D and 3D with respect to Virtual Reality

(c) What is Shading? Explain the various algorithms of it.

(a) What is marker-less tracking for augmented reality?

Marker-less tracking is a technique used in augmented reality (AR) that allows for the tracking of real-world objects without the use of markers or any external reference points. It involves the use of computer vision algorithms and sensors, such as cameras or depth sensors, to detect and track natural features in the environment. These natural features can include corners, edges, and other distinctive patterns on surfaces, which the algorithm uses to establish a reference frame for tracking and overlaying digital content.

One of the main advantages of marker-less tracking is that it allows for more flexible and natural interaction between the user and the AR experience, as there are no markers or fiducial points that the user needs to align or track. However, it can also be more challenging to implement, as the algorithm needs to be robust enough to detect and track features in varying lighting conditions, angles, and distances. There are several different marker-less tracking algorithms, including feature-based tracking, model-based tracking, and SLAM (Simultaneous Localization and Mapping) tracking, each with its own strengths and limitations.

(b) Explain the visualization techniques for augmented reality.

(c) Discuss the use of virtual reality in Education field.


(a) Write short note on Google Card Board.

Google Cardboard is a low-cost virtual reality headset developed by Google that allows users to experience virtual reality content using a smartphone. It is made of cardboard, hence the name, and uses a smartphone’s display and processing power to provide an immersive virtual reality experience.

To use Google Cardboard, users need to download a compatible app on their smartphone and insert the phone into the Cardboard headset. The app displays two images on the smartphone screen, one for each eye, which creates a stereoscopic 3D effect when viewed through the lenses in the Cardboard headset.

Google Cardboard was introduced in 2014 and quickly gained popularity as an affordable and accessible way for people to experience virtual reality. It has since been used in various fields, including education, gaming, and entertainment. In the education field, Google Cardboard has been used to create virtual field trips, allowing students to explore historical sites, natural wonders, and other locations without leaving the classroom. It has also been used to create interactive learning experiences, such as virtual dissection and laboratory simulations, which enhance the learning experience and provide a safe and cost-effective alternative to traditional methods.

(b) Explain the role of eyes, ears and senses in Augmented Reality

(c) Discuss the use of virtual reality in Film industry.

(a) What is VRML (Virtual Reality Modeling Language)?

VRML stands for Virtual Reality Modeling Language. It is a programming language that is used to create 3D models and virtual environments. It was developed in the mid-1990s and was one of the first standards for creating 3D graphics on the web.

VRML files are created using text editors or 3D modeling software and are saved in a standard format with the .wrl file extension. These files can be viewed using a VRML browser or a virtual reality headset.

VRML supports a wide range of features, including animation, interactivity, and scripting. It also supports the integration of multimedia elements, such as images, sounds, and videos, into the virtual environment.
