  • Line stylization through graphics processor unit (GPU) textures
    Patent number: 10540789
    Abstract: A method, apparatus, system, and computer program product provide the ability to render a line having line stylization/linetype pattern via texture mapping of a graphics processing unit (GPU). Linetype information for a pattern of a linetype for the line is acquired. The pattern is stored in a texture by encoding a type of element of the pattern and a texel center location. The GPU renders the line by computing a distance between a pixel of the line and the texel center location, determining if the distance exceeds a threshold, and rendering the pixel if the distance is within the threshold.

  • Spatial index compression through spatial subdivision encoding
    Patent number: 6463180
    Abstract: A technique for reducing the total storage used in representing data having spatial extents. The data is represented in a tree structure having a plurality of nodes, wherein each of the nodes has parent and child relationship to one or more others of the nodes in the tree structure. An encoded representation of the relation of a child node's extents with respect to its parent is stored in the node. A preorder traversal of the tree structure is performed to store it compactly in an output file.
