Considering global illumination in a dynamical environment, the hierarchical radiosity method is essential. In this paper, we propose a new scene partitioning scheme, light source beam, it enhances the hierarchical radiosity for dynamic environments. A significant integration of relationship in geometry between the light source and object surfaces simplifies the visibility calculation efficiently. Also, energy links we have to recalculation when a change in geometric occurs can be identified effectively. And, We create the visibility link to enhance the recalculation of energy links.
