The book begins by defining what computer graphics is—distinguishing between passive graphics (static images) and interactive graphics. Goel provides crisp definitions of:
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.
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.
In the realm of academic computer science education in India, certain textbooks transcend mere syllabus fulfillment to become trusted companions for students. One such revered title is the "Computer Graphics Book by Sushil Goel." For over a decade, this book has served as a foundational pillar for undergraduate and postgraduate students (specifically those in B.Tech, BCA, MCA, and M.Sc. IT programs).
While international authors like Foley, Van Dam, and Hearn & Baker offer encyclopedic depth, Sushil Goel’s work provides something uniquely valuable for the Indian subcontinent: clarity, exam-oriented precision, and affordable accessibility. This article explores the features, structure, and enduring relevance of Sushil Goel’s contribution to computer graphics education.
This is where static drawings become dynamic animations. The textbook excels at explaining the Transformation Matrix. computer graphics book by sushil goel
The book opens by demystifying the Raster Scan Display vs. Random Scan Display. Goel uses simple diagrams to explain interlacing, resolution, and aspect ratio.

Many students find the ellipse or parabola drawing algorithms daunting. Goel often breaks down equations into tabular iterative steps. For example, the Bresenham decision parameter is presented as a loop table (k=0,1,2...), allowing students to manually calculate pixel positions by hand—a common exam requirement.
