dc.description.abstract-translatedMany of current rendering methods for participating media need a large storage space a huge computations but do not simulate realistic media. Most of the time, it is due to the way the media are sampled. A fine sampling leads to a good representation of the optical and physical properties of media but requests often powerful computers and huge memory space. That´s why we present a new sampling solution. It is based on analytic shapes to model volume boundaries and variation functions to model volume properties. The sample is fitted to the ray while it is crossing the medium. An independent solution is proposed for the multiple scattering effects. This new approach has numerous advantages. With a low memory and computation cost, the medium parameters are easy to change. The most important advantage is that all the physical and optical properties of volumes are designed, even the multiple scattering. Moreover, the density varies inside the medium using a non-linear function. Thus, we can represent a wide range of participating media without making important change in the implementation.en
