A Short Introduction to Computer Graphics

Three-dimensional computer graphics architecture

Three-dimensional (3D) computer graphics hardware has emerged as an integral part of mainstream desktop PC systems. The aim of this paper is to describe the 3D graphics architecture at a level accessible to the general computational science community. We start with the generic 3D graphics rendering algorithm, the computational requirements of each of its steps, and the basic architectural featu...

Accessibility Analysis Using Computer Graphics Hardware

Analyzing the accessibility of an object's surface to probes or tools is important for many planning and programming tasks that involve spatial reasoning and arise in robotics and automation. This paper presents novel and eecient algorithms for computing accessible directions for tactile probes used in 3-D digitization with Coordinate Measuring Machines. The algorithms are executed in standard ...

Mediated Reality Using Computer Graphics Hardware for Computer Vision

Wearable, camera based, head–tracking systems use spatial image registration algorithms to align images taken as the wearer gazes around their environment. This allows for computer–generated information to appear to the user as though it was anchored in the real world. Often, these algorithms require creation of a multiscale Gaussian pyramid or repetitive re–projection of the images. Such opera...
