Computer Graphics by Amrendra N. Sinha and Arun D. Udai: A Review
Computer graphics is a fascinating field that combines art, science, and technology to create realistic and immersive visual experiences. Whether it is for entertainment, education, or research, computer graphics has many applications and challenges that require both creativity and technical skills.
One of the books that aims to introduce the concepts and implementation of computer graphics is Computer Graphics by Amrendra N. Sinha and Arun D. Udai. This book is written for students who wish to learn not only the theory but also the practical aspects of computer graphics. It is a comprehensive text that covers the basics as well as the advanced topics of computer graphics.
What does the book cover?
The book is divided into 12 chapters that cover the following topics:
Introduction to computer graphics: This chapter gives an overview of the history, applications, and hardware of computer graphics. It also introduces some basic concepts such as coordinate systems, transformations, clipping, and rasterization.
Mathematical preliminaries: This chapter reviews some mathematical concepts that are essential for computer graphics, such as vectors, matrices, curves, surfaces, and solids.
Scan conversion: This chapter explains how to convert geometric primitives such as points, lines, circles, ellipses, polygons, and curves into discrete pixels on a raster display.
Two-dimensional transformations: This chapter discusses how to perform geometric transformations such as translation, rotation, scaling, shearing, reflection, and composite transformations on two-dimensional objects.
Windowing and clipping: This chapter describes how to define a viewing window and clip objects that are outside the window using various algorithms such as Cohen-Sutherland, Liang-Barsky, Sutherland-Hodgman, and Weiler-Atherton.
Three-dimensional transformations: This chapter extends the concepts of two-dimensional transformations to three dimensions. It also introduces homogeneous coordinates and perspective projection.
Hidden surface removal: This chapter deals with the problem of determining which surfaces are visible and which are hidden from a given viewpoint. It presents various algorithms such as depth buffer (z-buffer), scan-line z-buffer, painter's algorithm, BSP trees, ray casting, and ray tracing.
Shading and illumination: This chapter explains how to model the interaction of light with objects and produce realistic shading effects. It covers topics such as light sources, ambient light, diffuse reflection, specular reflection, Phong model, Gouraud shading, Phong shading, and global illumination.
Color models: This chapter introduces different color models such as RGB, CMYK, HSV, HSL, CIE XYZ, CIE L*a*b*, and CIE L*u*v*. It also discusses color quantization and dithering techniques.
Curves and surfaces: This chapter covers various methods of representing curves and surfaces such as parametric curves (Bezier curves, B-splines), implicit curves (conic sections), parametric surfaces (Bezier patches), implicit surfaces (quadrics), subdivision surfaces (Catmull-Clark), and NURBS (non-uniform rational B-splines).
Solid modeling: This chapter introduces some techniques for modeling solid objects such as constructive solid geometry (CSG), boundary representation (B-rep), sweep representation (sweeping), spatial partitioning (octrees), voxel representation (voxels), and fractal geometry (fractals).
Animation: This chapter discusses some principles and techniques of animation such as keyframing, interpolation (linear interpolation,
