System and method for highlighting a feature in a 3D map while preserving depth
Abstract:
Systems and methods for rendering 3D maps may highlight a feature in a 3D map while preserving depth. A map tool of a mapping or navigation application that detects the selection of a feature in a 3D map (e.g., by touch) may perform a ray intersection to determine the feature that was selected. The map tool may capture the frame to be displayed (with the selected feature highlighted) in several steps. Each step may translate the map about a pivot point of the selected map feature (e.g., in three or four directions) to capture a new frame. The captured frames may be blended together to create a blurred map view that depicts 3D depth in the scene. A crisp version of the selected feature may then be rendered within the otherwise blurred 3D map. Color, brightness, contrast, or saturation values may be modified to further highlight the selected feature.
