Write a C-code for an interactive program which allows a user to draw a polygon object in a window and then gives various choices of geometric transformations on the polygon. Once the user selects a choice, the transformed polygon is also plotted on the window. To begin with, you can use a triangle in place of a polygon.
Translation, Rotation and Scaling - output primitives 1. Two basic approaches used in character generation are - Bitmap method and outline method. 2. All 2D geometric tran
Step1: Read a text file which we want to hide. Step2: Transform it into an array of its binary value. Step3: Transform this array into its equivalent one dimensional array
Question : (a) What do you understand by the term ‘contone'? (b) What are spot colours? (c) You have been asked to prepare an artwork (a magazine) to send to a printer.
What is scaling and shearing? The scaling transformations alters the shape of an object and can be carried out by multiplying every vertex (x,y) by scaling factor Sx, Sy where
De Casteljau Algorithm For computation of Bézier curves an iterative algorithm known as de Casteljau algorithm is used. The algorithm uses repeated linear interpolation.
Characteristics of vector drawings: Vector drawings are generally pretty small files as they include only data about the Bezier curves which form the drawing. The EPS-file format
Importance of Multimedia: Multimedia will help in spreading the information age to millions of teachers/learners. Today Multimedia educational computing is fastest raising markets
Problem with Interpolated Shading There are several more shading models that intermediate in complication among Gouraud and Phong shading, linking the liner interpolation of t
