## What is viewing explain the 2D viewing transformation?

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 mapping of a part of a world coordinate scene to device coordinate is referred to as viewing transformation.

## What is viewing transformation Mcq?

Explanation: The process of mapping the window port to view port is termed as ‘Window to view port Transformation’. It is also known as ‘Viewing Transformation’ or ‘Windowing Transformation’.

## How do you pixels are addressed in the seed fill algorithm *?

First of all, a starting pixel called as the seed is considered. The algorithm checks boundary pixel or adjacent pixels are colored or not. If the adjacent pixel is already filled or colored then leave it, otherwise fill it. The filling is done using four connected or eight connected approaches.

## What are viewing coordinates?

Viewing Transformation is the mapping of coordinates of points and lines that form the picture into appropriate coordinates on the display device. World coordinate system (WCS) is the right handed cartesian co-ordinate system where we define the picture to be displayed. A finite region in the WCS is called the Window.

## What are the steps involved in 2D viewing pipeline?

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 do you mean by 2D transformation?

2D Transformation. Transformation means changing some graphics into something else by applying rules. We can have various types of transformations such as translation, scaling up or down, rotation, shearing, etc. When a transformation takes place on a 2D plane, it is called 2D transformation.

## Which of the following equation is used in 2D translation to move a point?

Explanation: The 2D translation equation is P’=P+T.

## What is the process of mapping of coordinates in the display of an image *?

5. The process of mapping a world window in World Coordinates to the Viewport is called Viewing transformation. Explanation: The viewing transformation is the operation of computer graphics in which the maps are the perspective view of an object in world coordinates into a physical device’s display space.
