Procedural Representation of Three-Dimensional Objects
نویسنده
چکیده
A system of PL/I procedures has been written that permits geometric objects to be described hierarchically. The objects are themselves represented as P L / I procedures, allowing very general use of variables. By effectively intercepting subprogram calls, the system provides a means of modifying the semantics associated with any object without modifying the object’s procedural description
