Abstract
A parametric geometric element definition and generation system and method is described herein. 3D model of geometric objects are generated by execution of one or more directed acyclic graphs having a plurality of nodes which represent various modeling operations and parameters or properties used in defining and generating geometric elements. In further embodiments, an object player monitors modeling operations of nodes and communications with the rendering system to dynamically adapt the performance and format of the rendering system. A notification mechanism is used where nodes may send and/or listen for change events. A modification to one or more properties of node or nodes may trigger the transmission of a change event throughout the directed graph.
