System and method for combining independent scene layers to form computer generated environments
First Claim
Patent Images
1. A method for combining scene layers from independent databases to form a computer generated environment and associated images, comprising the steps of:
- processing a terrain database containing terrain data;
constructing a terrain layer that is stored in a data structure, and the terrain layer is constructed using the terrain data;
processing a feature layer database containing feature data;
generating a feature layer using the feature data that is separate from the terrain data, wherein features in the feature layer have locations in reference to the terrain layer;
combining the feature layer and the terrain layer to form a composite environment; and
rendering the composite environment for viewing by a user.

Abstract
A system and method is provided for combining independent scene layers to form computer generated environments. The method includes the operation of constructing a terrain layer using stored terrain data. Another operation is generating a feature layer using feature layer data that is stored separately from the stored terrain data. The feature layer and the terrain layer can then be combined to form a composite scene.

10. A system for combining independent scene layers to form computer generated environments, comprising:
-
a terrain database configured to store a terrain layer;
a feature database that is separate from the terrain database and configured to store a feature layer; and
a scene assembler configured to receive the terrain layer from the terrain database and the feature layer from the feature database in order to combine the terrain layer and the feature layer into a composite environment. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
