This paper presents a system for creating a full 360-degree panorama from rectilinear images captured from a single nodal position. The solution to the problem is divided into three steps. The first step registers all overlapping images projectively.

Image-based virtual reality is emerging as a major alternative to the more traditional 3D-based VR. The main advantages of the image-based VR are its photoquality realism and 3D illusion without any 3D information. Unfortunately, creating content for

Publisher Summary This chapter presents an algorithm for computing the inverse square root. In computer graphics calculations, the square root is often followed by a division, as when normalizing vectors. This adds a significant amount of computation

Publisher Summary This chapter describes an algorithm for calculating fixed-point square root. Many graphics algorithms rely upon fixed-point arithmetic and its inherent speed advantage over floating point. Often, a fixed-point algorithm requires the

Global illumination rendering involves the simulation of light interreflections between emitting and reflecting surfaces. Accounting for global illumination is necessary in the quest to generate images indistinguishable from real photographs. However

Publisher Summary This chapter presents an algebraic solution to the rendering problem of circular arcs. These forms commonly arise in graphic design. For instance, well-designed typefaces may apply a very slight curvature on a portion of a letterfor

Even though a signal is sampled, we may have certain rules about inferring the values between the sample points. The most common assumption made in signal processing is that the signal is bandlimited to an extent consistent with the sampling rate, i.

Introduction to the CORDIC Technique CORDIC is an acronym that stands for COordinate Rotation DIgital Computer, and was coined by Volder [Volder 59]. Its concepts have been further developed to include calculation of the Discrete Fourier Transform [D

We demonstrate the use of coordinate frames to simpli- fy transformations. We show how to specify coordinate transfor- mations without trigonometry. The viewing transformation is sim- plified considerably by specifying it in terms of coordinate frame
