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.

A method for combining independent scene layers to form computer generated environments, comprising the steps of:
- constructing a terrain layer using stored terrain data;
- generating a feature layer using feature layer data that is configured to be modified independently and stored separately from the stored terrain data;
- applying different run-time response rules to the terrain layer and the feature layer;
- combining the feature layer and the terrain layer to form a composite environment;
- and
- rendering the composite environment for viewing.
A method for combining independent scene layers to form computer generated environments, comprising the steps of:
- a. constructing a terrain layer using stored terrain data;
- b. generating a feature layer using feature layer data that is stored separately from the stored terrain data;
- c. combining the feature layer and the terrain layer to form a composite environment;
- and
- d. defining a run-time response rule for the terrain layer and a different run-time response rule for the feature layer.
