Model management in virtual reality research

In this paper, a Bi-angle Model Management method (BiMM) is proposed to manage models in virtual reality research. One angle is based on the model itself, which includes the model, model scheme, and texture; another angle is based on the model sort - each sort has its child sorts except leaf nodes. Based on this method, we have developed a model management application that has the following major functions: model management, model sort management, model query, model statistics, model registration into database as a whole, etc. With this method, researchers can manage model data conveniently and efficiently.
