A multi-instance, multi-user animation platform includes a plurality of modeled parallel dimensions in a computer memory. Each of the parallel dimensions may be an independent model of a physical, three-dimensional space having corresponding features such that the parallel dimensions are recognizable as counterparts to each other. Avatars are located within corresponding ones of the parallel dimensions so as to prevent over-population of any one of the parallel dimensions by avatars. Avatars are animated within different ones of the parallel dimensions using input from respective users to provide virtual-reality data. A common space is modeled in the computer memory configured in relation to the plurality of parallel instances so that an object located inside the common space is visible from viewpoints located inside each of the plurality of parallel instances. Remote clients may output an animated display of a corresponding one of the parallel dimensions and avatars therein.
