A new method, Global Newton-Raphson (GNR), for forward kinematics analysis of six degree–of-freedom (DOF) parallel robots is proposed, in order to obtain direct solutions of parallel robots in real time without divergence. The parallel robot can produce 3-DOF linear motions and 3-DOF angular motions, and feeds back positions of actuators measured by position sensors in real time. The GNR for the robot...
The real-time distributed computing environment and reusable software architecture are important factors that affect the fidelity of flight simulation. We accomplished a flight simulator based on DDS (data distribution service for real-time systems) middleware and structural software architecture and proved its high fidelity as a flight training device. According to the analysis of flight simulator's...
Flight simulator is among the most sophisticated software systems in existence. It is highly distributed, has rigorous timing requirements, and must be amenable to frequent updates to maintain high fidelity with the ever-changing vehicle and environment it is simulating. We proposed an optimized distributed real-time simulation framework to facilitate the high fidelity flight simulator research. It...
For efficient visualization, storage and management of massive datasets in current large-scale terrain rendering system, a real-time rendering algorithm of large-scale terrain based on GPU (graphic processing unit) is proposed. The algorithm is an out-of-core supported aggregated LOD (level of detail) rendering method and focuses on the use of GPUs' ability in the computation and programmability....
