Shadows.
We investigate the brightness distribution in and around outdoor shadows (for a variety of sky conditions) using modeling and field measurements. The dominant factor influencing the brightness of a shadow is the solid angle subtended by the object blocking the Sun. Occulters at the zenith that subtend a small solid angle cast shadows that are bright and possess a nearly uniform brightness acros...
متن کاملShadows.
It is almost 160 years since Dr James McDonnell delivered an address to the students entering the Belfast General Hospital. Since that time it has fallen upon a member of this staff to welcome those students who have commenced their first year in the clinical branches of medicine. This year it is my privilege and honour to address and welcome you on behalf of the medical and dental staff of thi...
متن کاملInduction The dance of shadows
Statistics stems out from induction. Induction is a long lasting notion in philosophy. The nature of notions in philosophy are such that neither they can be solved completely nor one can leave them forever. One of the most important problem in induction is “the problem of induction”. In this paper we give a short history of induction and discuss some aspects of the problem of induction.
متن کاملSelf Shadows and Cast Shadows in Estimating Illumination Distribution
This paper compares two methods for estimating illumination distributions from shadows: methods using self shadows and cast shadows. The cast shadow method provides an effective framework for recovering illuminations in a real scene utilizing variations of image brightnesses inside shadows cast by an occluding object of known shape. The shadow surface is typically the same plane on which the ob...
متن کاملShadows and Soft Shadows with Participating Media Using Splatting
— This paper describes an efficient algorithm to model the light attenuation due to a participating media with low albedo. Here, we consider the light attenuation along a ray, as well as the light attenuation emanating from a surface. The light attenuation is modeled using a splatting volume renderer for both the viewer and the light source. During the rendering, a 2D shadow buffer accumulates ...
