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.

What is claimed is: 1. 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. 2. A method as in claim 1, wherein the step of generating a feature layer further comprises the step of generating a plurality of feature layers that are configured to be combined together with other feature and terrain layers. 3. A method as in claim 1, further comprising the step of determining the locations of features in the feature layer in reference to the terrain layer. 4. A method as in claim 1, wherein the step of rendering the composite environment for viewing further comprises the step of resolving conflicts between layers. 5. A method as in claim 1, further comprising the step of defining different run-time response rules for the terrain layer and the feature layer. 6. A method as in claim 5, wherein the step of defining different run-time response rules for the terrain layer and the feature layer further comprises providing a level-of-detail control for the terrain layer and a separate level-of-detail control for the feature layer. 7. A method as in claim 5, wherein the step of defining different run-time response rules for the terrain layer and the feature layer further comprises specifying a field-of-view control for the terrain layer and a separate field-of-view control for the feature layer. 8. A method as in claim 1, further comprising the steps of: modifying the feature layer; and recompiling the feature layer independently from the terrain layer. 9. 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. 10. A method as in claim 9, wherein the step of defining different run-time response rules for the terrain layer and the feature layer further comprises providing a level-of-detail control for the terrain layer and a separate level-of-detail control for the feature layer. 11. A method as in claim 9, wherein the step of defining different run-time response rules for the terrain layer and the feature layer further comprises specifying a field-of-view control for the terrain layer and a separate field-of-view control for the feature layer. 12. 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; combining the feature layer and the terrain layer to form a composite environment; and defining a run-time response rule for the terrain layer and a different run-time response rule for the feature layer. 13. A method as in claim 12, further comprising the step of rendering the composite environment for viewing. 14. A method as in claim 13, wherein the step of rendering the composite environment for viewing further comprises the step of applying different run-time response rules to the terrain layer and the feature layer. 15. A method as in claim 13, wherein the step of rendering the composite environment for viewing further comprises the step of resolving conflicts between layers.
