Abstract
To generate realistic representation of the nature scene is one of the most challenging areas in the computer graphics community. Ray tracing is the most well-known technique to synthesize a realistic image. Since ray tracing is the most suitable method for simulating reflection and refraction of the light, it has been used for simulating various atmospheric optical phenomena caused by them. Mirage is a kind of atmospheric optical phenomena. Therefore, it is possible to replicate mirages in 3DCG by simulating or modeling condition of the air. We focus on pencil tracing technique that is an extension of the conventional ray tracing technique based on the paraxial approximation theory. Our simple method based on pencil tracing can efficiently generate the appearance of mirages without complex thermodynamic simulation.
