Running heavy scenes faster using BSP trees

Until recently, one could only dream of creating a complex indoor environment in Away3D.To set up a scene with a system of several rooms was an extremely difficult task in terms of performance and although some companies quite succeeded in creating a relatively complex environment, they were still highly restricted in the amount of geometry they could afford as well as the optimization work consumed a bulk of the total development time. Eventually, the Away3D team came up with the solution known as BSP trees a term widely used in industrial real-time game engines. Without entering into details on how those trees work, you should know that they significantly increase performance of quite heavy scenes ...
