Computer Graphics Through OpenGL: From Theory to Experiments, Second Edition




Computer graphics is a fascinating field that combines mathematics, physics, art, and programming to create realistic and interactive 3D scenes and animations. If you are interested in learning computer graphics, you may want to check out the book Computer Graphics Through OpenGL: From Theory to Experiments, Second Edition by Sumanta Guha.




Computer Graphics Through OpenGL: From Theory to Experiments, Second Edition



This book is a comprehensive introduction to computer graphics that uses an active learning style to teach key concepts. It covers topics such as geometric primitives, animation, 3D modeling, lighting, shading, texturing, curves, surfaces, transformations, and more. It also teaches you how to use the OpenGL Application Programming Interface (API) to code 3D scenes and animation, including games and movies.


What is OpenGL?




OpenGL is a cross-platform, low-level API for rendering 2D and 3D graphics. It is widely used in the industry and academia for developing applications such as video games, simulations, virtual reality, computer-aided design, and scientific visualization. OpenGL allows you to access the graphics hardware of your computer and control how pixels are drawn on the screen.


OpenGL is not a programming language, but a set of commands that you can use in your program to specify what you want to draw and how. You can use OpenGL with any programming language that supports it, such as C, C++, Java, Python, etc. However, you need to have some basic knowledge of linear algebra and geometry to understand how OpenGL works.


What are the benefits of learning computer graphics through OpenGL?




Learning computer graphics through OpenGL has several benefits:


  • You can learn the fundamental concepts of 3D computer graphics in a practical way.



  • You can see the results of your code immediately on the screen and experiment with different parameters and effects.



  • You can develop your own applications using OpenGL and showcase your creativity and skills.



  • You can prepare yourself for more advanced topics and techniques in computer graphics.



  • You can use OpenGL as a stepping stone to learn other graphics APIs such as DirectX, Vulkan, Metal, etc.



What are the features of Computer Graphics Through OpenGL: From Theory to Experiments, Second Edition?




The book has several features that make it an ideal choice for learning computer graphics through OpenGL:


  • It is written in a clear and engaging style that explains the theory and practice of computer graphics in an accessible way.



  • It provides an understanding not only of the principles of 3D computer graphics but also of the use of the OpenGL API to code 3D scenes and animation.

  • It covers both fixed-function pipeline and programmable pipeline approaches to OpenGL programming. It also introduces new features of OpenGL 4.3 such as shaders, vertex buffer objects, occlusion culling, texture matrices, multisampling, point sprites, pixel buffer objects, shadow mapping, etc.



  • It explores more advanced topics such as the structure of curves and surfaces and the application of projective spaces and transformations.



  • It includes an instructor's manual with solutions to 100 problems (for qualifying instructors only).
