Abstract: The subject disclosure is directed towards an object (e.g., an aspected vector, queue, map, stack and so forth) container having an exclusive interface, a shared-read-only interface and a shared-write (and read) interface to a common set of data. Use cases during runtime determine the appropriate interface to use. No locking is needed with methods of the exclusive interface or the read-only interface. The shared-write interface is configured to have only concurrency safe methods. Also described is blocking the use of other interfaces while one interface is in use, and the use of reference counter tracking to know when no concurrent readers and/or writers remain, to allow transitioning to use a different interface.

Abstract: A method for collecting, managing, manipulating, and checking data during construction of a virtual environment, and automatically re-processing the subset of data necessary to produce a resource for use by a simulation program, is provided. This method provides for the repeated application of a designated material to commonly designated elements of multiple objects. Once the material has been designated to be applied to a particular element of an object, application to other objects is facilitated by designating the common element. This method significantly reduces the amount of repetitive artist labor related to iterated operations performed and features improved error detection and indication.
