windowing, rasterization, Graphics Pipeline, Hidden Surface Removal, Object
hierarchies, fractals, L-systems, Cubic Curves and Bicubic Surfaces, Meshes,
Lighting, Material, Shading, texture mapping, environment mapping, shadows and
interreflections.
This
comprehensive lecture note by Prof. Vijay M. Shekat comprehensively explains the
basics that surround the fundamental concepts in computer graphics. The basics
of computer graphics, such as the principles and application of graphics
primitives, are explained-entities required to display a picture. The note
throws light on the 2D transformations and viewing techniques that form an
important approach toward manipulating and displaying two-dimensional graphics.
The text also covers 3D concepts and object representation, which are important
in acquiring knowledge about the complexity of three-dimensional modeling. The
discussion covers 3D transformations and viewing, and a deep view is taken in
how objects are manipulated and viewed in three-dimensional space. Advanced
topics are also covered and may include recent developments and sophisticated
techniques of computer graphics, making this note very useful for students and
professionals who want to learn both the basics and the advanced aspects of the
subject.
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.
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.
This
note is concentrated on computer graphics, integrated with multimedia,
applications, and systems. It covers basic graphics system architecture and the
output primitives that are commonly used to display images. Also, it explains
the basic two-dimensional geometric transformations and viewing techniques,
three-dimensional object representation, and transformation. The illumination
model and methods of rendering surfaces will also be discussed to highlight how
the properties of light and material result in visual appearance. It also covers
topics relevant to the multimedia components-digital audio and digital
images-since working with graphics now increasingly involves their integration
in a combined fashion for multimedia presentation.

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.
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.
