Abstract
A multi-resolution representation of a radiosity equation for a scene is constructed. The scene comprises object elements and steps are performed to identify specialised cluster elements by associating object elements having a characterising relationship. Elements are linked and/or meshed in response to an estimate of error of light transmission between the elements. The linking includes the process of calculating a form factor and when linking a specialised cluster, the form factor is calculated with reference to the characterising relationship. The characterising relationship may be, for example, near co-planarity and in this way the overall processing and calculation requirements are reduced.
