  • 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.

  • Out-of-core point rendering with dynamic shapes
    Patent number: 10347034
    Abstract: A method, apparatus, and system provides the ability to process and render a point cloud. The points in the point cloud are grouped into three-dimensional (3D) voxels. A position of each of the points is stored in the point data file. The position is with respect to a location of the point's corresponding 3D voxel. Surface normal data for a surface normal associated with each of the points is also stored in the point data file. The points are organized into levels of details (LODs). The point data file is provided to a graphics processing unit (GPU) that processes the point data file to render the point cloud. During rendering, a LOD is selected to determine the points in the point cloud to render.
