Computer Graphics : PU [SEM 4] - Comp & IT




Introduction


       The subject Computer Graphics was introduced into the IT syllabus from the 2008 pattern in the 4th semester. Earlier in the 2003 pattern I.T. had computer graphics in the 5th semester under the title 'Multimedia'. Computer Engg had it in the 4th sem of the curriculum even in the 2003 pattern. Syllabus for Comp and IT is quite different, around 3 to 3.5 units in common.

Overview

     Computer Grpahics aka CG is a simple and easy to learn subject. Very interesting and also scoring. The subject includes a 100 marks Theory paper , 50 marks practical  i.e. CG&OOPL and 50 marks term work. This subject does not need tedious efforts to score even though a major part of this subject is theoretical. Even though 80% of the subject being theoretical  it is pretty easy to score 65+ without strenous efforts.And of course,you can definitely  score 70+ but it requires quality efforts.

Books to Refer


Among the local authors, I would recommend Technical. Techmax publication is good but section 2 in Techmax is poorly organized and explained. People who are referring Techmax..I would suggest at least use Technical for Section 2.

Among the foreign authors "Introduction to Computer Graphics" - Steven Harrington and "Procedural Elements for Computer Graphics"  - Davis Roger. These two will  suffice. You should also fire your queries on google which will actually help you in understanding the subject better. Wikipeia is another important resource for Computer Graphics.

Analysis of the Subject 


Unit 1:
Introduces to you the basic concepts of Computer Graphics. Easy to learn and is interesting. Many concepts which we actually assume to be known are cleared in this unit. It is relatively vast but not at all difficult. The unit introduces  to you different algorithms which are new to you. These algorithms should be learnt..or instead you will  learn it in your practicals.

Unit 2 :
This unit is less time consuming when compared to the 1st unit. Easy to learn.This unit is scoring....as many sums are asked usually from this unit. The unit also introduces 3 main algorithms of computer graphics which you will  be implementing in your practicals. Algorithms are a must learn.

Unit 3:
A bit boring when we compare the contents to the other units. This unit is also time consuming as it introduces many new concepts. No practical assignments are covered from this unit.

Unit 4 :
Section 2 of computer graphics has very less contents and topics when we compare to section 1. Its almost half of section 1 when we compare in terms of number of pages. This unit has new concepts introduced .This unit is really interesting to learn. It is theoretical, some people may unfortunately find it a bit confusing in the first go. But over a couple of glances ...things become more easy and interesting.

Unit 5 :
Very small unit in terms of number of pages, this unit is really intersting BUT not for everyone. People who are actually fond of multimedia and physics to certain extent will like this unit...others will have realtively a bit tough time learning this unit . 100% theoretical....that is the problem which makes it difficult to learn and remember. Multiple glances through the contents are definitely required.....

Unit 6 :
The questions  to be asked are quite predictable from this unit. Totally theoretical...you will need to mug up many equations ...without which it wont work!!.. Small unit BUT...its really time consuming. 

Verdict


Computer Graphics i.e. CG is a simple , easy to learn, interesting and pretty scoring subject. Please do not assume that you can complete the section 2 of this subject in a day during your exams looking at the size  of the Local author textbook. Section II even though not more than 60-65 pages, it is completely  theoreticalvery confusing and time consuming if you try finishing the book in a day!
