Abstract: A system and method is disclosed for resolving visual priority among coincident primitives for a computer graphics system. The method can include the operation of classifying primitives within a computer generated scene into an ordinary group and one or more coincident groups according to each primitive's visual depth set comprising a depth value, a group value, and a layer value. The primitives within the ordinary group can be rendered according to their depth value. The primitives within the same coincident group can be rendered according to their layer value.

Abstract: A system and method is provided for modeling a world database that is a spheroid in a computer graphics simulation system. The method includes the operation of modeling the world database using a plurality of geodetic terrain gridposts. A further operation is creating a triangulated network mesh based on the geodetic terrain gridposts in real-time as a function of eye position. In addition, the triangulated network mesh is stored in geodetic coordinates. The triangulated network mesh is then rendered using geometry formed by the triangulated network mesh.

Abstract: A method is disclosed for rendering a volumetric obscurant in a computer generated graphical image. The method can include the operation of defining a polygon template as a first surface of the volumetric obscurant comprising pixels and sub-pixels. A further operation can be spreading a depth of the sub-pixels for pixels in the polygon template to create a thickness in the volumetric obscurant. Finally, another operation can be modulating a depth density of the sub-pixels to vary the distances between the sub-pixels in the volumetric obscurant.
