Remarkable Atmospheric Phenomena in Ceylon

Simulation of atmospheric phenomena

This paper presents a physically based simulation of atmospheric phenomena. It takes into account the physics of non-homogeneous media in which the index of refraction varies continuously, creating curved light paths. As opposed to previous research on this area, we solve the physically based differential equation that describes the trajectory of light. We develop an accurate expression of the ...

Efficient Rendering of Atmospheric Phenomena

Rendering o f atmospheric bodies involves modeling the complex interaction o f light throughout the highly scat­ tering medium o f water and air particles. Scattering by these particles creates many well-known atmospheric optical phenomena including rainbows, halos, the corona, and the glory. Unfortunately, most radiative transport approximations in computer graphics are ill-suited to render co...

Pterygium in Ceylon.

The geographical situation of Ceylon led Cameron (I965) to suggest that the pterygium rate there would range from 5-5 to over io per cent., but the actual incidence appears to be much less for reasons which are discussed below. The incidence of pterygium has not been closely studied, first perhaps because it rarely causes blindness, secondly because the world's earliest eye hospitals were situa...
