Abstract in different language:	This paper focuses on how to calculate, with radiosity techniques, images associated to different scenes which take into account both an isotropic diffuse participating media and specular surfaces. To do so, we propose a new expression of the form factors defined in the zonal method. The first part of this article briefly quotes the expression of energetic exchanges by using operators and zonal method equations. The second part deals with the different changes brought to the zonal method in order to express it under the form of operators first and then redefine its form factors. Finally, we will treat of computational considerations and see how different images enable us to show the many possibilities of our algorithm.
