Such utilization requires advanced modeling capabilities, especially for irregular solid objects. In this context, the suitability and limitations of the octree structure are examined, along with other representaiton schemes. Finally, a prototype system, produced as a result of this research, is outlined.\r\n\r\n \r\n\r\nView more or order: here
