Evaluation of 3D Data Compression and Retrieval Method Based on Curve Mesh Filling
Abstract. Digital mock-up (DMU) and/or compound document with 3D data are one of the most important methods to represent a product model. Since 3D models become greater year by year, 3D data compression and retrieval algorithm is required to easily exchange such information through the internet. Because broadband is still not popular in some regions in the world, it is necessary to send huge data in a small size as much as possible. A number of methods have been developed to compress 3D surface models; Wakita et al adopted surface interpolation method using Gregory patches. However, the surface interpolation method cannot be applied to the concave shapes or shapes with holes. To overcome this problem, Muraki et al. proposed a surface compression method using a surface fitting method. In this paper, the performance of the 3D surface compression and retrieval algorithm based on a curve mesh interpolation and N-side filling is evaluated. To be more concrete, an application system that transfers 3D surface models has been firstly developed. After that, the performance is evaluated with different network environments: such as third generation of mobile telecommunications (3G) and Worldwide Interoperability for Microwave Access (WiMAX).
