Abstract
A computer-readable medium having stored thereon an applications programming interface for causing a computer system to render a three-dimensional scene according to a downloaded file. A scene graph is constructed from a number of objects stored in memory. These objects have variables which can be changed by subroutine calls. Furthermore, one or more objects can contain one or more fields. A field is comprised of a data type which represents the state of an object. Engines are used to perform defined functions to the fields. One or more routes can be used to change one field in response to changes made to another field. A class hierarchy is defined to implement a retained mode graphics.
