Curvilinear 3D GIS Graphics Viewpoint Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing GIS technologies face challenges in displaying advertisements in 3D environments, as rectangular billboards can be distorted and not clearly visible from all viewpoints, leading to an intrusive and unrealistic user experience due to limited perspectives.
Innovation Solution
Implementing curvilinear representations of graphics, such as cylindrical or spherical shapes, that adjust and orient themselves directly towards the user's viewpoint, ensuring visibility and minimizing distortion across various perspectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If rectangular billboards are applied to flat surfaces in 3D GIS environments, then advertisements can be displayed, but the billboards become distorted and not clearly visible from certain viewpoints
Solution Approach 1:
The patent applies curvature by transforming flat rectangular billboards into curvilinear surfaces (cylindrical or conical) that wrap around 3D geographical features. This allows the advertisement surface to conform to the curved geometry of the environment, maintaining visual consistency and readability from multiple viewpoints without the distortion that plagues flat billboards in 3D space.
Solution Approach 2:
The patent implements dynamic adjustment of billboard orientation and positioning based on the user's viewpoint. The billboards automatically reorient themselves to face the user or adjust their visible surface, ensuring that advertisements remain clearly visible and undistorted regardless of the user's position or movement through the 3D environment.
2Loss of information
If rectangular billboards are positioned on storefronts, then advertisements can be displayed, but part of the storefront is hidden and the billboards are intrusive
Solution Approach 1:
The patent nests the advertisement billboard within or around the existing storefront structure by wrapping it around 3D geographical features. Instead of placing a flat billboard on the storefront surface that obscures the building, the curvilinear billboard conforms to and integrates with the surrounding environment, allowing the storefront to remain visible while displaying the advertisement.
Solution Approach 2:
The patent transitions from 2D flat billboards to 3D curvilinear surfaces that wrap around geographical features. This dimensional change allows advertisements to be displayed in space around the storefront rather than on its surface, reducing occlusion and creating a more integrated, less intrusive display that respects the original storefront visibility.
3Ease of operation
If incremental navigation is used in 3D GIS, then users can navigate through the environment, but available perspectives are limited and some billboards cannot be clearly seen
Solution Approach 1:
The patent makes the billboards dynamic by enabling them to reorient and reposition themselves based on the user's current viewpoint and navigation position. As users move through the 3D environment with incremental navigation, the billboards automatically adjust their orientation to face the user or optimize their visibility, ensuring that advertisements remain clearly seen from any navigation position without requiring the user to stop at specific predetermined locations.

AI summary
Methods and systems for providing a graphic, such as an advertisement, in a 3D geographical information system (GIS) view are described. A method for providing a graphic in a 3D GIS view may include obtaining a graphic and determining a 3D geographical space in the GIS view based on a geographical reference in the GIS view. The method may also include rendering and displaying a curvilinear representation of the graphic in the geographical space. The method may further include adjusting the curvilinear representation of the graphic according to an updated viewpoint of the GIS view. The curvilinear representation may be oriented directly towards the updated viewpoint. A system for providing a graphic in a 3D GIS view may include a geographical space manager, a graphic representation generator and a display module.
