Abstract

Mixed-reality systems are provided for using anchor data structures, such as anchor graphs, within a mixed-reality environment. These systems utilize anchor components, such as anchor vertexes, that comprise at least one first key frame, a first mixed-reality element, and at least one first transform connecting the at least one first key frame to the first mixed-reality element. Anchor connecting components, such as anchor edges, comprise transformations that connect the anchor components (e.g., anchor vertexes).

Claims20

Dependent claims

A computer system for connecting anchor components in a mixed-reality environment, comprising:

one or more processors;
and
one or more computer-readable medium having stored computer-executable instructions that are executable by the one or more processors to cause the computer system to perform a method that includes at least the following:
identifying a first anchor component in the mixed-reality environment that includes a first mixed-reality element and at least one first key frame that is connected to the first mixed-reality element with at least one first transform;
identifying a second anchor component in the mixed-reality environment that includes a second mixed-reality element and at least one second key frame that is connected to the second mixed-reality element with at least one second transform;
and
creating an anchor connecting component that includes a single connecting transform that connects the first anchor component to the second anchor component and which omits at least a separate transform between an individual key frame in the first anchor component with an individual key frame in the second anchor component.
