An apparatus and method for partitioning a three-dimensional graphical environment for displaying representative images of objects in a database dependent on the database of objects and their associated metadata is described. According to the apparatus and method, the database of objects is represented by a hierarchical tree derived from the object metadata (20). The tree includes parent nodes (23, 24, 25), their associated child nodes (24, 25, 26), and data object nodes (26), where every node has an associated weight. A predetermined parent node (23) is pre-assigned an area (27) corresponding to the undivided graphical environment. Then, for each parent node having at least two associated child nodes in the tree, the area is recursively divided (22) into a plurality of areas corresponding to each of the associated child nodes such that the areas are proportional to the child node weights.
