Abstract: A computer can identify discrete objects within a 3D geometry in a vector-based format. The computer can compare a spatial property of each of the discrete objects against an established spatial range. From the comparing, the computer can determining that a set of the discrete objects have a spatial property within the spatial range. The computer can omit the discrete objects from the 3D geometry as a group to create an altered 3D geometry. The computer can submit the altered 3D geometry to a render engine for display. The number of polygons in the altered 3D geometry is less than the number of polygon faces in the 3D geometry.

Abstract: A method for identifying, by at least one processor, at least one feature in a raster image based on a set of extraction parameters, and generating, by the at least one processor, a feature path file conforming to a vector format, the feature path file represents a plurality of instances of the at least one feature in the raster image. A system and computer program product are also disclosed.

Abstract: A polygon mesh may have a plurality of vertices and a set of polygon faces. Each of the triangles defining candidate planes may include one of the vertices as an endpoint of each line segment. For each of the candidate planes, an area or a number of vertices, referred to as a point count, may be computed. The candidate planes may be ordered by decreasing area or by decreasing point count. A planar face may be selected in accordance with the ordering. The selected planar face may be added to a set of polygon faces for a modified polygon mesh. Non-selected ones of the candidate planes may be excluded, whenever the non-selected candidate plane overlaps in area with an already selected planar polygon face. The selecting and the excluding may be repeated until the modified polygon mesh is formed. The modified polygon mesh may be a tessellation in three dimensions.
