Optimal Combination of Multi-resolution Models in Visualization Techniques

Complex VR scenes, containing hundreds of multi-resolution models with millions polygons, cannot achieve real-time performance and verisimilitude at the same time. How to adaptively choose the appropriate level of resolutions according to the data volume and hardware/software environment is therefore a critical issue. This paper we propose an optimization algorithm to choose the model resolutions that maximize scene quality while meeting timing constraints. The mathematical model is given by means of the relationship between scene representation and model resolution. Lagrange multiplier method is used to solve the problem of extreme value solution under time constraints.
