An advanced data generation system for use in complex object synthesis for computer display

An integrated system for the creation and modification of three dimensionCl I datil for use in imilC'W synthesis is described. The hierarchical organization of the system functions is shown, and several of these functions are detailed. The system is designed so that a user can create a large class of three dimensional objects in an intuitive fashion without an extensive knowledge of the internal workings of the software and the associated data structure .
