Abstract
A fundamental element of computer graphics is produc-
ing realistic visualizations of various natural phenomena.
An important problem in this area is that of rendering
scenes containing atmospheric effects, which arise from
the absorbtion and scattering of light due to small parti-
cles such as dust and smoke. Generating photorealistic
renderings through ray-tracing is computationally very
demanding because of the time needed to perform numer-
ical integration along the length of each ray to determine
the opacity and color of the gaseous media.
We present a new data structure and algorithm for effi-
ciently rendering atmospheric effects. Our approach is
