Foveated 3D model simplification

Visualization of 3D images is becoming more commonplace for a variety of applications including online games and e-commerce. For efficient online visualization of 3D objects it is necessary to quickly adapt 3D models (including the wireframe and texture) to the available computational or network resources. In this paper we propose enhancements to 3D model simplification based on interactive level-of-detail (LOD) update with foveation. Our technique differs from the others in that simplification is based on both surface curvature surface and the region of interest. Data structures to implement model simplification are also described. Experimental results comparing the simplified models and the computational time demonstrate the feasibility of our approach.
