Q.2. Explain Bresenham’s line-drawing algorithm and write its advantages over the DDA line-drawing algorithm.

Ans 2.

Bresenham’s Line-Drawing Algorithm

Bresenham’s line drawing algorithm is a raster scanning algorithm that determines the number of areas of the screen that must be turned towards drawing straight lines between two endpoints specified on a screen. It was developed by Jack Bresenham in 1962. The algorithm is solely based on the concept of integers, making it extremely efficient for software implementation.

The basic idea is to determine incrementally the next pixel to be plotted through the evaluation of

 

Q.3. Explain the different transformations of 2D.

Ans 3.

A 2D transformation is a mathematical process that alters the position, size, orientation or shape of objects in a two-dimensional coordinate system. These transformations are essential in computer graphics and find application in various areas such as animation, game development,

Q.4. Explain the Depth Sorting Method and write its advantages and disadvantages.

Ans 4.

Depth Sorting Method

The Depth Sorting Method, also called the Painter’s Algorithm, is a technique used for 3D computer graphics to assess the visibility of surfaces and render them in the right order. The algorithm solves the hidden issue of surface removal by sorting all polygons or surfaces in the scene starting from the most distant from the closest one to the viewer and then painting them

 

 

Q.5. Explain the RGB color model. How it is different from the CMYK color model?

Ans 5.

RGB Color Model

The RGB color model is an additive model of color with colors created using three fundamental colors of light, Red, Green, and Blue. The model is built on the premise that our eyes detect color using three kinds of cone cells sensitive to red, green, as well as blue wavelengths. Through mixing the three colors at different intensities, a broad range of colors may be produced.

When using digital technology, every color channel is represented by a value ranging from zero

Q.6. Explain different types of frames used in compression through redundancy.

Ans 6.

Redundancy in video compression is a term used to define the repetition of details that are able to be removed or predicted to reduce file size without significant loss of quality. The most significant technique employed in video compression standards like MPEG uses frames of different varieties. They exploit two major types of redundancy: spatial redundancy within one frame and temporal redundancy between consecutive frames.

1. I-Frame (Intra-coded Frame)

A I-frame, also known as an Intra-coded frame, is an entire independent image. It is compressed
