## What is 3D viewing pipeline?

14. █ 3D-Viewing-Pipeline. The viewing-pipeline in 3 dimensions is almost the same as the 2D-viewing-pipeline. Only after the definition of the viewing direction and orientation (i.e., of the camera) an additional projection step is done, which is the reduction of 3D-data onto a projection plane: norm.

## What are the stages in 3D viewing?

Three-Dimensional Viewing

- THREE-DIMENSIONAL VIEWING.
- Specifying the View Plane.
- PROJECTIONS.
- Perspective projection.
- THREE-DIMENSIONAL VIEWING FUNCTIONS.

**What is 3D viewing?**

A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.

**What is 3D viewing transformation?**

In Computer graphics, 3D Translation is a process of moving an object from one position to another in a three dimensional plane. Consider a point object O has to be moved from one position to another in a 3D plane.

### What are 3D viewing devices?

The 3D viewing device comprises a body, two displays, two light sources, and two sets of projection lenses. The body is adapted to externally connect to a head-worn device. The body has a space therein, and a base side and opposite lateral sides neighboring thereto.

### What is 3D object representation?

Objects are represented as a collection of surfaces. 3D object representation is divided into two categories. Boundary Representations B−reps − It describes a 3D object as a set of surfaces that separates the object interior from the environment.

**What is viewing pipeline in computer graphics?**

The term Viewing Pipeline describes a series of transformations, which are passed by geometry data to end up as image data being displayed on a device. The 2D viewing pipeline describes this process for 2D data: norm.

**What are applications of 3D viewing?**

3D is an excellent medium to make more representational models, visuals or movies in Design, Engineering, CAD/CAM and Simulation applications. 3D models enable the viewer to fully appreciate the final appearance of an engineered product.

## Why do we need 3D viewing devices?

The physical world around us is three-dimensional (3D), yet traditional display devices can show only two-dimensional (2D) flat images that lack depth (i.e., the third dimension) information. This fundamental restriction greatly limits our ability to perceive and to understand the complexity of real-world objects.

## What is 3D form?

3D shapes are shapes with three dimensions, such as width, height and depth. An example of a 3D shape is a prism or a sphere. 3D shapes are multidimensional and can be physically held.

**What are different techniques for 3D transformation?**

Transformation Techniques-

- Translation.
- Rotation.
- Scaling.
- Reflection.
- Shear.

**What is 2D viewing and viewing pipeline?**

Two dimensional viewing The viewing pipeline A world coordinate area selected for display is called a window. An area on a display device to which a window is mapped is called a view port. The window defines what is to be viewed the view port defines where it is to be displayed.
