OpenCSG - The CSG rendering library. Real-Time Rendering Resources. Nate Robins - Main. Computer Vision: Algorithms and Applications. © 2010 Richard Szeliski Welcome to the Web site ( for my computer vision textbook, which you can now purchase at a variety of locations, including Springer (SpringerLink, DOI), Amazon, and Barnes & Noble.
The book is also available in Chinese and Japanese (translated by Prof. Toru Tamaki). This book is largely based on the computer vision courses that I have co-taught at the University of Washington (2008, 2005, 2001) and Stanford (2003) with Steve Seitz and David Fleet. You are welcome to download the PDF from this Web site for personal use, but not to repost it on any other Web site. The PDFs should be enabled for commenting directly in your viewer. If you have any comments or feedback on the book, please send me e-mail. This Web site will also eventually contain supplementary materials for the textbook, such as figures and images from the book, slides sets, pointers to software, and a bibliography.

Real-Time Rendering Resources. Tutorial - Getting Started with the OpenGL Shading Language (GLSL) - joshbeam.com. Tutorial - Getting Started with the OpenGL Shading Language (GLSL) This article provides an introduction to the OpenGL Shading Language (GLSL).
It contains sample C and GLSL code, and is accompanied by a diffuse/specular lighting demo with full source code. The code is available under an open source, BSD-style license and was designed to be as simple as possible, so that it can easily be used in other projects. Overview of GLSL If you're not familiar with shaders, they are small programs that are executed on a per-vertex or per-pixel basis during drawing operations (there are also geometry shaders, which operate on geometric primitives, but they will not be covered in this tutorial).
Although there were various other extensions for using shaders with OpenGL in the past, the OpenGL Shading Language (or GLSL for short) has been an official part of the OpenGL standard since version 2.0 and is now the preferred language for implementing shaders in OpenGL. Shader and Program Objects. Tutorial - Introduction to Software-based Rendering: Simple Line Drawing - joshbeam.com. Tutorial - Introduction to Software-based Rendering: Simple Line Drawing This tutorial starts off a series of articles on software-based graphics rendering by introducing a simple line drawing algorithm.
It contains sample C++ code and is accompanied by a demo program with full source code that uses SDL for display. Rasterization First, a quick overview of this basic process of 3D graphics rendering is in order. Although real-time 3D graphics rendering is a vast and complex subject area with many different concepts and techniques, most of it basically consists of simple geometric shapes, primarily triangles, that are drawn in such a way that they appear to form a much more complex image. The process of drawing the triangles is called rasterization. A triangle, for instance, consists of three points.
