Hybrid shading model based on device performance for LOD adaptive service

초록

This paper proposes an adaptive method for providing a single set of contents to various device environments simultaneously in real time. Using meshes with multiple levels of resolution has been proposed as an adaptive method for 3D graphic contents according to the capacity of device environment and user requirements. This study proposes a standard algorithm for selecting an appropriate level in a mesh model and a shading technique for performing rendering with low capacity and performance devices. The proposed shading technique is an improvement from the existing Gouraud and flat shading libraries. It offers an effective alternative by applying different shading schemes in each of multiple polygons to reduce the time required for real-time rendering, merits that are expected to be very useful in real-time adaptive services. © 2008 Springer Berlin Heidelberg.
