The method comprises identifying a number of faces in the mesh model and constructing an adjacency graph of connections between the faces. A value is assigned to each connection in the adjacency graph according to a metric of similarity between incident faces of the connection.

From the remaining connections in the adjacency graph a number of strongly connected components in the mesh model are determined.

Abstract: An exemplary three-dimensional (3D) simulation system accesses a two-dimensional (2D) video image captured by a video capture device and that depicts a bounded real-world scene and a real-world object present within the bounded real-world scene. The 3D simulation system accesses respective 3D models of the bounded real-world scene and the real-world object. Based on the 2D video image, the 3D simulation system tracks a spatial characteristic of the real-world object relative to the bounded real-world scene. Based on the tracked spatial characteristic of the real-world object and the 3D models of the bounded real-world scene and the real-world object, the 3D simulation system generates a 3D simulation of the bounded real-world scene within which the real-world object is simulated in accordance with the tracked spatial characteristic of the real-world object. Corresponding methods and systems are also disclosed.

Abstract: Systems and methods are described that provide for distributively storing and accessing data across multiple hash tables, such that utilization of the hash tables is optimized. In particular, a key associated with a value is split into two or more sub-keys and the sub-keys are inserted into respective hash tables with associated values. For each sub-key except the final sub-key derived from a particular key, the value paired with the sub-key is an identifier that points to the location of the next sub-key and its associated value, which may be stored in the other hash tables. The final sub-key derived from the original key is paired with the value associated with the key, such as an action to be performed. Thus, rather than using a single key (which may be very large) to access or store a particular value, multiple (smaller) sub-keys are used to ultimately access the same value via multiple, smaller hash tables.
