Computer Graphics and Image Processing

Concept based notes Computer Graphics by Bindiya Patel

The book of Bindiya Patel from Biyani College Jaipur provides a more organized way of approaching the concept of computer graphics. The notes start with discussing graphics applications and raster graphics, hence laying a foundation of how images are created and manipulated on digital systems. Key topics that will be discussed include transformations-essential processes to change graphical objects-and output primitives-the basic elements used in drawing. Some of the notes also cover clipping algorithms, which are very important in showing only visible parts of the graphics. It explains the different methods for visible surface detection, answering how a particular surface in a scene would be visible or invisible. It also describes curves and surfaces-important in the case of higher degree shapes-and briefly describes image processing to integrate computer graphics with other visual technologies.

Computer Graphics by AAGASC

The following textbook by Arignar Anna Government Arts and Science College gives an overview of computer graphics systems in some detail. It begins with the overall architecture of computer graphics systems in order to place into context how such graphical applications are built and executed. Output primitives discussed in this book are the basic elements used in constructing an image. Also, there is a discussion about 2D geometric transformations for manipulating two-dimensional objects. It contains parts on the graphical user interface and the methods of interactive input that are very important when one is designing graphics applications that should be friendly to users. Geometric and modeling transformations concerning 3D graphics are dealt with in the book at the description of how to create and modify three-dimensional objects. Hence, the resource is helpful in studying both the basic issues of computer graphics systems and its applications.

Lecture Notes On Computer Graphics

The set of lecture notes provides an overview of some important topics related to computer graphics. It starts with the application of computer graphics, extending to various areas where graphical techniques are indispensable. The lecture notes discuss the basic algorithms for drawing lines like Bresenham's algorithm and go further to give details on two-dimensional transformation, such as scaling, rotation, and translation. Concepts about 2D viewing and representation of 3D objects with their transformation have been discussed. This is done by explaining methods for visible-surface detection. Finally, an understanding of some general concepts of the way dynamic visual content is produced and manipulated in computer animation is provided.

Computer Graphics Lecture Notes by Clinton L. Jeffery

The following are the notes from Clinton L. Jeffery on aspects in both the theoretical and practical aspects of computer graphics. An introduction to hardware in graphics and frame buffers is given first, followed by the description of line drawing techniques and the parameters for API. Next come color indices, colormaps, and raster operations-forming the very basics necessary to understand color and graphics management. These notes also extend to the UI graphics primitives, region filling, and advanced concepts such as the Golden Rectangle. There is great emphasis on OpenGL, GLU, and GLUT, which really establishes modern graphics programming. Other topics involve the Phong shading model, texture mapping, and 3D model file formats that make these notes comprehensive toward understanding the principles underlying many practical applications in computer graphics.

Computer Graphics by Seoul National University

Notes from Seoul National University, this set provides an excellent introduction to some of the more theoretical and practical aspects of computer graphics. It covers the more basic areas of scan conversion and clipping - both important areas in rendering and image processing. Detailed discussions on Windows programming, sampling techniques, 2D and 3D geometric transformations, and viewing methods are included. The curriculum also covers DirectX for device creation and vertex rendering, hidden surface removal, and matrix usage. It considers texture mapping and lighting, curve, and surface modeling. The material gains a good understanding of both fixed and programmable pipelines and thus would be useful to students and professionals interested in practical implementation related to computer graphics technologies.

Computer Graphics Lecture Notes by MIT

These lecture notes, by Prof. Wojciech Matusik and Prof. Fredo Durand, summarize the algorithms, software, and hardware used in computer graphics. The notes will introduce essential concepts: ray tracing and the graphics pipeline, to render realistic images. Further, various transformations will be introduced, along with the generation of shadows and texture mapping. Further topics in the curriculum include methods of sampling, global illumination, and splines in order to give a wide view on rendering and image synthesis, while animation and color theory are added to the completion of visual representation understanding. These notes are ideal for those seeking indepth studies of advanced graphics techniques and their applications, from basic principles to complex rendering and illumination models.
