Abstract: Systems and methods for block based level of detail representation are described herein. A method embodiment includes extracting one or more 3D models from 3D data, grouping the 3D models based on one or more attributes of the 3D models, distributing the grouped 3D models to a plurality of resolution levels of a geospatial data structure, and merging the grouped 3D models as a combined 3D model. A system embodiment includes a prepossessing system configured to extract one or more 3D models from 3D data and a block level of detail (LOD) creator configured to group the 3D models based on one or more attributes of the 3D models, and to render the grouped 3D models as a combined 3D model.

Abstract: Embodiments provide a system and method for height based indexing of data. In an embodiment, the present invention parses indexed data by (1) storing a geo-spatial multi-resolution data structure that represents a three dimensional environment, where at least a portion of the three dimensional environment lies within a view frustum; (2) traversing recursively the geo-spatial multi-resolution data structure, where the traversal is based on a range of coordinates that lie within the view frustum; and (3) extracting the indexed data from at least one vertical slice of at least one node of the geo-spatial multi-resolution data structure, where the extracted indexed data is displayed in the view frustum.

Abstract: Three-dimensional scenes or movies are generated by a user of a computer system by interactively selecting a stage from among several available 3D stages, each of which has at least one predetermined feature such as a pedestal, lighting characteristics, a camera path or the like. The user may import predefined 3D objects into the selected stage and move and resize the objects as desired to compose a scene. Once composed, the scene is rendered to generate an image or a series of successive scenes is rendered to generate an animated movie.

Abstract: A system, method and computer program product for optimizing a scene graph for optimizing rendering performance. The nodes of an original scene graph are rearranged to minimize a number of state changes while rendering the scene graph. The shapes of the original scene graph are further broken into a plurality of triangular strip sets, which lend to a better rendering performance. The system, method and computer program product also performs transformations on an object in the scene graph and sends the transformed object to a rendering library, which minimizes an amount of data transferred to the rendering library.
