Developing Physics Simulation in Augmented Reality

Use of a physics engine to drive a virtual scene is becoming more common. Physics simulations aim to model the behaviors of objects in space so as to provide realistic motions in computer animation, thereby enriching the interaction and user experience in augmented reality. In this paper, we present a cross-platform environment in which handheld and desktop-computer users can collaborate with each other in a shared scene to accomplish physically realistic experiences during the course of interaction. In realizing the system, we explore and exploit several novel techniques, including bare-hand manipulation, a client/server computing framework, a tangible mobile phone interface, and a distributed scene graph structure. To demonstrate the effectiveness of the system, we developed JengAR, a simulation of the well-known tower building game

ViWoSG: A distributed scene graph of ultramassive distributed virtual environments

An ultra-massive distributed virtual environment generally consists of ultra-massive terrain data and a large quantity of objects and their attribute data, such as 2D/3D geometric models, audio/video, images, vectors, characteristics, etc. In this paper, we propose a novel method for constructing distributed scene graphs with high extensibility. Thismethod can support high concurrent interaction of clients and implement various tasks such as editing, querying, accessing and motion controlling. Some application experiments are performed to demonstrate its efficiency and soundness.

Myriad: scalable VR via peer-to-peer connectivity, PC clustering, and transient inconsistency

Distributed scene graphs are important in virtual reality, both in collaborative virtual environments and in cluster rendering. Modern scalable visualization systems have high local throughput, but...
