Graphics Book By Sushil Goel — Computer
It is likely you are referring to one of two possibilities:
- A local/Indian-published exam guide – Often, authors like Sushil Goel write “textbooks” for specific Indian university syllabi (e.g., UPTU, RTU, MDU). These books typically contain condensed notes, previous exam questions, and summaries, not rigorous algorithmic or mathematical content.
- A misspelling – You may mean Sushil Jajodia (database/security) or Sumanta Guha (author of Computer Graphics Through OpenGL).
1. The "University Exam" Focus
Unlike western textbooks that focus on programming projects, Sushil Goel’s book is designed for theorem-proof and numerical problem-solving. Every chapter ends with:
- "Short Answer Questions" (2 marks)
- "Long Answer Numerical Problems" (5-10 marks)
- "Derivation Questions" (7 marks)
Unit 5: Hidden Surface Removal & Illumination
Hidden Surface Removal
- Back-face culling
- Z-buffer (depth buffer) – algorithm + advantages/disadvantages
- Painter’s algorithm
- Scan-line depth algorithm
Illumination Models
- Ambient, diffuse, specular (Phong reflection model)
- Gourand vs. Phong shading
- Constant shading
Sample Problem
Compare Z-buffer and Painter’s algorithm. When does Painter’s fail?
Exam Tip – Numerical on Phong lighting is rare but conceptual comparison is common.
Where to Buy the Latest Edition
When searching for the "Computer Graphics Book by Sushil Goel," ensure you are buying the latest revised edition (typically the 5th or 6th edition). Be aware that the title may vary slightly: computer graphics book by sushil goel

Availability:
- Online: Amazon.in, Flipkart, or the Khanna Publishing website.
- Offline: Most campus bookstores in Delhi, Noida, Pune, Bengaluru, and Kolkata stock it heavily during July/January (semester start).
- E-book: Some editions are available via the Kopykitab or Google Play Books platform.
In-Depth Table of Contents and Syllabus Mapping
The strength of this book lies in how meticulously it follows the standard CS/IT Engineering syllabus (common to AICTE model curriculum). Below is a chapter-wise breakdown of what you can expect.
How to Study Using the Computer Graphics Book by Sushil Goel
Based on feedback from top-performing CS students, here is a 4-week study plan using this book. It is likely you are referring to one of two possibilities:
Unit 5: 3D Projections & Hidden Surfaces
- Projections: Perspective (1-point, 2-point) vs. Parallel (Orthographic, Oblique).
- Hidden Surface Removal: Back-face detection, Depth Buffer (Z-buffer) algorithm, Painter’s algorithm.
- Illumination: Basic light models (Ambient, Diffuse, Specular) and Gourard/Phong shading.
Unit 1: The Foundation of Graphics Systems
The book begins by defining what computer graphics is—distinguishing between passive graphics (static images) and interactive graphics. Goel provides crisp definitions of:
- CRT Technology: Raster scan vs. Random scan (a favorite 5-mark question).
- Color Models: RGB vs. CMY—explained with color cubes.
- Output Primitives: Basic geometry definitions.
Why Goel excels here: He uses simple black-and-white diagrams (rare in expensive color textbooks) that are easy to replicate in exam answer sheets.
