INTEGRATION OF LABELS INTO A 3D GEOSPATIAL MODEL

摘要

Architecture that enables the representation of labels as objects in the 3D (three-dimensional) world, with size, elevation, and orientation. Logical hierarchies in the world are represented by the placement and prominence of labels in the 3D world scene. For example, state labels are positioned higher and larger than city labels. The illusion of the label as a fixed element in the 3D model is maintained during manipulations. Additionally, movement is provided to ensure legibility, but is delayed until the user's input is quiescent. Moreover, labels along roads, for example, can be oriented to stand vertically along a curve.
