A cloud platform prototype for Computer Aided Engineering (CAE) simulation is developed for the large-scale parallel CAE simulation application. We propose the architecture of the platform. In the architecture, we propose a technology called CAE Application Packaging Template (CAE-APT) for integrating heterogeneous CAE softwares based on "Tianhe No.1". We discuss the design ideas and the...
In order to accurately construct the modeling of a telerobot in a virtual environment and reduce the work of developing the graphic design, this paper took the XK-II telerobot as a prototype, using SolidWorks modeling and interactive graphics programming with Open Inventor. First of all, we constructed each entities' geometric model in SolidWorks, and then, derived these models into VRML files and...
This paper presents a new mesh simplification algorithm based on edge collapse, it combines surface curvature and quadric error metric, the position of a new vertex for edge collapse depends on multiple-weighted approach. The new algorithm can improve simplification rationality in procedure and preserve important features after simplification. In an addition, we do some experiments with comparing...
In this paper, a new method for real-time rendering of three-dimensional terrain is proposed. The method combines together several methods such as block data, view-dependent multi-resolution LOD, view frustum culling etc. It exploits a new method to measure the terrain curvature. The new method uses multiple-approach to simplify terrain model and reduce the cost of memory, which can improve efficient...
A method that flatten surface of 3D model is presented. It can flatten the surface of model into a 2D shape as well as automatically cut and partition. The method avoids global and local self-intersections and minimizes the total length of the introduced seams. Then, a 3D models retrieval methodology based on the shape comparison is proposed. By using areas of the triangles, the convexity of each...

Hybrid control system is heterogeneous and difficult to design and modeling. This paper presents a component-oriented design methodology that reduces complexity by separating computational parts from interaction among components. We introduce a concept of supervisor to discuss how to aggregate individual component's computation into a coarse-grained composite component from a view of interaction semantics...
