A Study on Four-Dimensional Geometric Modeling for Cyber Field (6th Report)

Reducing Computational Resources by Streaming Mesh Format and Mesh Simplification

Abstract

In this research, a four-dimensional mesh model has been proposed for construction of a cyber field which manages dynamic states of object models. The four-dimensional mesh model is generated by 4D-Marching Cubes algorithm and contains a great number of vertices and tetrahedrons; therefore the four-dimensional mesh model requires massive amounts of system memories. In this report, for reducing computational resources, the method for conversion of the four-dimensional mesh to a streaming mesh format is proposed. The streaming mesh format allows sequentially constructing a large model. In addition, the four-dimensional mesh simplification algorithm based on QEM is proposed. These methods are implemented and the efficiency of these methods is demonstrated from the results.
