Patent ID: 8031192

Claim:
A graphics engine for controlling a level of detail in a rendered object, the graphics engine configured to: identify a set of parent vertices defining corners of a polygon within the rendered object, the set of parent vertices comprising one or more parent vertices in a low level of detail area and one or more parent vertices in a high level of detail area, wherein sides of the polygon are defined by connecting corresponding pairs of parent vertices in the set of parent vertices; generate a corresponding child vertex for each pair of parent vertices, each child vertex connected to the corresponding pair of parent vertices; connect each child vertex to at least one other child vertex; determine whether both parent vertices of each corresponding pair of parent vertices that defines a side of the polygon lie within the low level of detail area; and relocate a corresponding child vertex along a side of the polygon toward a predetermined parent vertex in the corresponding pair of parent vertices following the determination that both parent vertices in the corresponding pair of parent vertices lie within the low level of detail.
