Object Oriented programming and Computer Graphics syllabus

Programming paradigms - Introduction to programming paradigms, Introduction to four main Programming paradigms- procedural, object oriented, functional, and logic & rule based. Need of objectoriented programming, Fundamentals of object-oriented programming: Namespaces, objects, classes, data members, methods, messages, data encapsulation, data abstraction and information hiding, inheritance, polymorphism. Benefits of OOP, Java as object oriented programming language. Overview of Java Language: simple Java program structure: documentation section, package statement, import statements, class definition, main method class. Implementing Java Program, JVM, Data types, Primitive Types vs. Reference type, floating point numbers, operators and expressions, Java Class Libraries, Typical Java Development Environment, and Memory Concepts. Control Statements: Selection Statements: if, if-else, nested if-else, Iteration Statements: do, while, for, for-each statement, break, and continue statements

Case Study: Analyze the object -oriented features in Java with other object oriented programming languages.

Introduction to Classes and Objects: Defining a Class, Field declaration, method declaration and definition, instantiating an object of a Class, Accessing class members, declaring methods with multiple parameters, argument passing, object as a parameter, returning objects, assigning object reference variables, set methods and get methods, constructors, this keyword, Constructors, static methods, scope of declaration, method overloading and Java API packages. Arrays: declaring and creating arrays in Java, examples using arrays, passing arrays to methods, multidimensional arrays, variable-length argument lists, using command-line arguments. Managing I/O: Streams Byte Streams and Character Streams, Predefined Streams, Reading console Input, Writing Console Output, Print Writer class.

Case Studies: Demonstrate an interactive Banking/Library management system using class, objects, array of objects

Inheritance: Super classes and Subclasses, protected members, relationship between super classes and subclasses, types of Inheritance, constructors in subclasses, object class. Polymorphism: Abstract classes and methods, final methods and classes, dynamic binding, polymorphism examples and Interfaces. Exception handling: fundamentals, Exception Types, Using try-catch, Multiple try-catch clauses, Nested try statements, throw, throws, finally, Built-in Exceptions MultiThreading: Java Thread Model, Main Thread, Creating a Thread , Creating Multiple Threads.

Case Study ; Demonstrate online Banking/Library system using Inheritance, Exception handling and Multi-Threading concepts

Introduction: graphics primitives - pixel, resolution, aspect ratio, frame buffer. Display devices, applications of computer graphics. Scan conversion: Line drawing algorithms: Digital Differential Analyzer (DDA), Bresenham. Circle drawing algorithms: DDA, Bresenham, and Midpoint. Polygons: Introduction to polygon, types: convex, concave and complex. Inside test. Polygon Filling: flood fill, seed fill, scan line fill. Windowing and clipping: viewing transformations, 2-D clipping: Cohen – Sutherland algorithm line Clipping algorithm, Sutherland Hodgeman polygon clipping algorithm.

Case Studies - 1) Real-Time Map Rendering in GPS Navigation Systems using Line and Circle Drawing Algorithms 2) 3D pipeline / polygonal modelling and applications

2-D Transformations: 2-D transformations - Translation, Scaling, Rotation and Shear, Rotation about an arbitrary point. 3-D Transformations: 3-D transformations - Translation, Scaling, Rotation and Shear, Rotation about an arbitrary axis. Projections: Parallel (Oblique: Cavalier, Cabinet and orthographic: isometric, diametric, trimetric) and Perspective (Vanishing Points – 1 point, 2 point and 3 point)

Case Studies - 1) Affine Transformations Vlab (Vlab link: https://cse19- iiith.vlabs.ac.in/exp/affinetransformation/theory.html) 2) Image augmentation in Deep learning
