Abstract: Systems and methods are disclosed for providing interactive displays of complex virtual environments. Systems and methods consistent with embodiments of the invention may be implemented to generate virtual reality (VR) file(s) from a 3D model of the complex environment. The VR file(s) may include octree and collision detection information that is used to simulate and render frames of the complex environment. During simulation, moving objects may be evaluated to detect for collisions with other objects. Further, during rendering, objects or elements may be dynamically tessellated during run-time operations to actively control their appearance when displayed to a user. Memory management operations for facilitating the display of complex virtual environments are also disclosed, consistent with embodiments of the invention.
