## Why is viewing transformation needed?

Remember that purpose of the viewing transformation **is to orient the objects in a coordinate system where the center of projection is located at the origin**. … This coordinate system is called either eye space or camera space.

## What is the viewport in computer graphics?

A viewport is **a polygon viewing region in computer graphics**. In computer graphics theory, there are two region-like notions of relevance when rendering some objects to an image. … In 3D computer graphics it refers to the 2D rectangle used to project the 3D scene to the position of a virtual camera.

## Why is transformation important in computer graphics?

Transformation means changing some graphics into something else by applying rules. … Transformations play an important role in computer graphics to **reposition the graphics on the screen and change their size or orientation**.

## What do you understand by viewing transformation?

Viewing Transformation is **the mapping of coordinates of points and lines that form the picture into appropriate coordinates on the display device**. … Mapping the window onto a subregion of the display device called the viewport is called the Viewing Transformation.

## What is the significance of 2D transformation?

When a transformation takes place on a 2D plane, it is called 2D transformation. Transformations **play an important role in computer graphics to reposition the graphics on the screen and change their size or orientation**.

## What is viewport performance?

CGDirector’s Cinema 4D Viewport Performance Benchmark **measures how snappy and smooth Active Work inside your 3D Software will be**. … In Cinema 4D and most 3D-Software, the Processor is responsible for a smooth Viewport experience and is rarely bottlenecked by the Graphics Card.

## What is viewing transformation explain in detail the various steps involved in the process?

The viewing transformation which maps picture co-ordinates in the WCS to display co-ordinates in PDCS is performed by the following transformations. **Converting world co-ordinates to viewing co-ordinates**. Normalizing viewing co-ordinates. Converting normalized viewing co-ordinates to device co-ordinates.

## What is 2D viewing transformation in computer graphics?

2D Transformations in Computer Graphics- Transformation is **a process of modifying and re-positioning the existing graphics**. 2D Transformations take place in a two dimensional plane.

## What is the need for concatenation of transformations?

Concatenation **combines two affine transformation matrices by multiplying them together**. You might perform several concatenations in order to create a single affine transform that contains the cumulative effects of several transformations.

## What is transformation matrix in computer graphics?

Transformation matrix is a basic tool for transformation. A matrix with **n x m dimensions is multiplied with the coordinate of objects**. Usually 3 x 3 or 4 x 4 matrices are used for transformation. For example, consider the following matrix for various operation.
