The interaction of thermal radiation with conduction and laminar natural convection in a vertical circular pin, situated at participating gas, is numerically investigated. An absorbing and emitting gas is considered, and treated to be a gray participating media. Under the idealizing of gray gas, the Rosselan4 approximation is employed to describe the radiative heat flux in the energy equation. ...

This paper focuses on realistic ray-tracing rendering of scenes which integrate participating media. We work on the temperature sensitive index of refraction, in order to deflect the rays' path and thus visualize a scene through heat. We can also visualize three-dimensional convective motions, under the shape of fumes. In this respect, we suggest to solve the NS (Navier-Stokes) equations throug...

Volume caustics are beautiful patterns of light which are formed by light that first interacts with a specular surface and that is then scattered inside a participating medium. Although this phenomenon can be simulated, its generation process is usually non-trivial and time-consuming. Motivated by interactive applications, we propose a novel volume caustics rendering method for single-scatterin...
