Efficient 3D object simplification and fragmented texture scaling for online visualization

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 simplification envelopes (ESE) and curvature variations (CPD) on the surface of an object. We compare the two approaches and demonstrate that the CPD method is much faster than ESE while producing comparable results. A technique for texture simplification driven by model simplification is also proposed. Experimental results comparing the simplified models and the computational time demonstrate the feasibility of our approach.
