Abstract: Computer-implemented systems and methods are provided for analyzing and determining properties of virtual environments rendered on a display. The disclosed embodiments include, for example, a method for obtaining, by one or more processors, one or more depth parameters comprising one or more display parameters reflecting characteristics of the display, wherein the display parameters include a height and width of the display, and one or more environment depth multipliers reflecting a scaling factor to optimize display performance. The method may also include calculating, by the one or more processors, a diagonal display distance based on the display parameters. The method may also include calculating, by the one or more processors, an environment depth based on the diagonal display distance and the one or more environment depth multipliers. The method may also include setting, by the one or more processors, the depth of the display equal to the environment depth.

Abstract: Computer-implemented systems and methods are provided for analyzing and determining properties of virtual environments rendered on a display. The disclosed embodiments include, for example, a method for rendering a virtual environment, the method comprising operations performed with one or more processors. The operations of the method may include generating a plurality of object layers, the object layers representing permissible height values. The method may also include populating the environment with a plurality of objects, wherein each object is associated with a height value corresponding to one of the object layers. The method may also include determining whether any two objects form an occluded pair. The method may also include calculating a cast shadow index for each occluded pair reflecting a magnitude of a height differential between occluding object and the occluded object. The method may also include rendering the virtual environment in accordance with the calculated cast shadow indices.

Abstract: Systems, methods, and computer-readable media are provided for generating an arced path of travel for a user interface element. In accordance with one implementation, a method is provided that includes operations performed by at least one processor. The operations of the method include determining coordinates for a start point and an end point of the user interface element corresponding to locations on a user interface. The method may also include determining a minimum arc angle and a maximum arc angle for an arc. Additionally, the method may generate an arced path based on the start point coordinates, the end point coordinates, the minimum arc angle, and the maximum arc angle. The method may also generate commands that move the user interface element along the arced path in the user interface.
