Book Description

What is Alpha Compositing In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. How you will benefit (I) Insights, and validations about the following topics: Chapter 1: Alpha compositing Chapter 2: Digital compositing Chapter 3: PNG Chapter 4: RGB color model Chapter 5: Gamma correction Chapter 6: Chroma subsampling Chapter 7: BMP file format Chapter 8: RGBA color model Chapter 9: Grayscale Chapter 10: Transparency (graphic) (II) Answering the public top questions about alpha compositing. (III) Real world examples for the usage of alpha compositing in many fields. Who this book is for Professionals, undergraduate and graduate students, enthusiasts, hobbyists, and those who want to go beyond basic knowledge or information for any kind of Alpha Compositing.

Book Description

Today truly useful and interactive graphics are available on affordable computers. While hardware progress has been impressive, widespread gains in software expertise have come more slowly. Information about advanced techniques—beyond those learned in introductory computer graphics texts—is not as easy to come by as inexpensive hardware. This book brings the graphics programmer beyond the basics and introduces them to advanced knowledge that is hard to obtain outside of an intensive CG work environment. The book is about graphics techniques—those that don't require esoteric hardware or custom graphics libraries—that are written in a comprehensive style and do useful things. It covers graphics that are not covered well in your old graphics textbook. But it also goes further, teaching you how to apply those techniques in real world applications, filling real world needs. - Emphasizes the algorithmic side of computer graphics, with a practical application focus, and provides usable techniques for real world problems. - Serves as an introduction to the techniques that are hard to obtain outside of an intensive computer graphics work environment. - Sophisticated and novel programming techniques are implemented in C using the OpenGL library, including coverage of color and lighting; texture mapping; blending and compositing; antialiasing; image processing; special effects; natural phenomena; artistic and non-photorealistic techniques, and many others.
