Abstract :
Ray-tracing methods are extended to include the mirage effect. This is accomplished by simulating atmospheric variations. Different air layers are distinguished in modeling the continuous spectrum of temperature change, each layer being assigned a refractive index, which causes a penetrating light ray to bend in accordance with Snell´s law of refraction. A classification of mirage images is included.<>
