Abstract: Systems, methods, devices, and non-transitory media of various embodiments enable prioritization of requests for hierarchical level of detail (HLOD) content over a communications network. Various embodiment methods may reduce load time of nodes in the HLOD data structure, such as nodes in the HLOD that may be deemed important, compared to the load time achieved in current methods. Various embodiments may provide methods for prioritizing requests for nodes.

Abstract: Systems, methods, devices, and non-transitory media of various embodiments enable subdividing large polygon meshes with diverse materials into a hierarchy of separate components, such as tiles. In various embodiments, the components may in aggregate represent the entire mesh. In the hierarchies of separate components as provided by the various embodiments, the components may be loaded as-needed based on importance, culled due to lack of importance to a given view, and/or replaced with higher or lower detail variants depending on importance to a given view. The ability to load components, such as tiles, on-demand provided by the various embodiments may provide improved rendering performance of a large polygon mesh with diverse materials, especially when the rendering leverages data transmission over a network.

Abstract: Systems, methods, devices, and non-transitory media of various embodiments render vector data on static and dynamic surfaces by a computing device for a graphic display or for a separate computing device and/or algorithm to generate an image. Complex vector data associated with a surface for rendering may be rendered. The complex vector data may be decomposed into one or more vector subunits. A geometry corresponding to a volume and a mathematical description of an extrusion of each corresponding vector subunit may be generated. The volume and the mathematical description of the extrusion may intersect a surface level-of-detail of the surface. The geometry may be rasterized as a screen-space decal. Also, a surface depth texture may be compared for the surface against the extrusion using at least the screen-space decal. In addition, geometry batching may be performed for drawing simultaneously a plurality of the one or more vector subunits.

Abstract: Systems and methods for three dimensional modeling using skipping heuristics and fusing are disclosed herein. An example method includes obtaining a plurality of three dimensional models of a target, each of the models having a unique resolution level, assembling an aggregate three dimensional model using a hierarchical tree representation of the plurality of three dimensional models by skipping levels of detail in the hierarchical tree and rendering the levels of the hierarchical tree that were not skipped. Fusing overlapping sections of the aggregate model can be accomplished using bivariate visibility testing.
