Adaptation method for level of detail (LOD) of 3D contents

초록

In this research we present a method for adaptation of 3D contents over ubiquitous environment. The need of contents adaptation and delivery is growing to support multiple target platforms for single source. Since contents base on computer graphics deal with a large data set and a high performance, a service adaptation for context changing is required to manipulate graphics contents with a more complicated method in multiple devices such as desktops, laptops, PDAs, mobile phones, etc. This paper presents some theoretical method for adaptation, which is Service Rendering Middleware, and device-based decision making algorithm for LOD of 3D contents. Service Rendering Middleware consists of Service Adaptation (SA) for analyzing environments, Service Rendering (SR) for reconfiguring customized services and LOD Algorithm for generating an adapted service by processing customized data according to the level of detail. Also, the decision-making algorithm, which is based on device capabilities, is used both in LOD algorithm module and method to decide level of 3D contents. © 2007 IEEE.
