Embodiment Construction

[0021] Reference will now be made in detail to embodiments, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the embodiment, not limitation of the present disclosure. In fact, it will be apparent to those skilled in the art that various modifications and changes can be made in the embodiments without departing from the scope or spirit of the present disclosure. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Accordingly, aspects of the present disclosure are intended to cover such modifications and variations.

[0022] Generally, the present disclosure relates to systems and methods for generating soft occlusion data for physical objects and using the soft occlusion data to render virtual elements relative to physical objects in an augmented or virtual reality environment. More specifically, the disclos...

Abstract

Systems and methods for rendering computer graphics using soft-occlusion are provided. A computing system can obtain display data for a virtual element to be displayed in association with imagery depicting an environment including a physical object. The computing system can generate a set of graphics occlusion parameters associated with rendering the image data and the display data based at leastin a part on an estimated geometry of the physical object,. The set of graphics occlusion parameters can define blending of the display data for the virtual element and the imagery at a soft-occlusionregion that includes one or more locations within the estimated geometry. The computing system can render a composite image from the display data for the virtual element and the imagery based at least in part on the set of graphics occlusion parameters.

Description

technical field [0001] The present disclosure generally relates to mapping applications that provide and / or display map data associated with geographic areas. Background technique [0002] A geographic information system (GIS) is a system for archiving, retrieving, and manipulating data that has been stored and indexed according to the geographic coordinates of its elements. The system can generally utilize various data types such as imagery, maps and tables. GIS technology can be integrated into Internet-based mapping applications. [0003] Such mapping applications may be, or may otherwise be associated with, software applications that display interactive digital maps. For example, mapping applications may run on laptop and tablet computers, mobile phones, car navigation systems, handheld global positioning system (GPS) units, and the like. In general, mapping applications can display various types of geographic data, including topographical data, street data, city tran...
