The goal of image synthesis is to create, using the computer, a visual experience that is
identical to what a viewer would experience when viewing a real environment. Radiosity …

A method to display the earth as viewed from outer space (or a spaceship) is proposed. The
intention of the paper is application to space flight simulators (eg, reentry to the atmosphere) …

The various types of shadows are characterized. Most existing shadow algorithms are
described, and their complexities, advantages, and shortcomings are discussed. Hard …

Methods to display realistic clouds are proposed. To display realistic images, a precise
shading model is required: two components should be considered. One is multiple …

Studio spotlights produce dazzling shafts of light, while light scattered from fog illuminated
by automobile headlights renders driving difficult. This is because the particles in the …

We present a method for the efficient re-rendering of a scene under a directional illuminant
at an arbitrary orientation. We take advantage of the linearity of the rendering operator with …

We present a technique for capturing the extreme dynamic range of natural illumination
environments that include the sun and sky, which has presented a challenge for traditional …

The Fourier projection-slice theorem allows projections of volume data to be generated in O
(n2 logn) time for a volume of size n3. The method operates by extracting and inverse …

In this paper, we present a new approach to producing photorealistic computer renderings of
real architectural scenes under novel lighting conditions, such as at different times of day …

The use of digital terrain models and computer graphics techniques have become a more
common method not only for generating computer visualisations of the terrain but also for …
