And another major difference is graphics, in 2D computer graphics are digital images. There are two types of graphics one is Raster graphics and another one is Vector graphics. Raster graphics or bitmap are composing by array of pixel, here each pixel has different color or shade.

Solution:-To determine the general form of the scaling matrix with respect to a fixed point P (h, k) we have to perform three steps: Translate point P(h, k) at the origin by performing translation (T1).

What is transformation? In many cases a complex picture can always be treated as a combination of straight line, circles, ellipse etc., and if we are able to generate these basic figures, we can also generate combinations of them. Once we have drawn these pictures, the need arises to transform these pictures.

This transformation when takes place in 2D plane, is known as 2D transformation. In order to reposition the graphics on the screen and change the size or orientation, Transformations play a crucial role in computer graphics. What are Homogenous Coordinates?

Classification of Computer Graphics by Object and Picture Type of Object 2D 3D Pictorial Representation Line drawing Gray scale image Color image Line drawing (or wire-frame) Line drawing, with various effects Shaded, color image with various effects Table 1.1 Computer graphics is used today in many different areas of industry, business.

Multiple choice questions on Computer Graphics topic Geometric Transformations. Practice these MCQ questions and answers for preparation of various competitive and entrance exams. A directory of Objective Type Questions covering all the Computer Science subjects.

Also note that all transformations are implemented in 2D. There are three basic kinds of Transformations in Computer Graphics: 1. Translation 2. Rotation 3. Scaling. Algorithms.

CS3162 Introduction to Computer Graphics Helena Wong, 2000 1 5. Three Dimensional Transformations Methods for geometric transforamtions and object modelling in 3D are extended from 2D methods by including the considerations for the z coordinate. Basic geometric transformations are: Translation, Rotation, Scaling 5.1 Basic Transformations.
