Mesh simplification algorithm based on screen resolution of mobile devices

Abstract

According to the feature that the mobile user's perception to 3D scene is considerably related to the screen resolution of the mobile devices,we put forward a mesh simplification algorithm based on screen resolution of the mobile devices.The new algorithm defined the Benchmark of View(BoV) when the model was displayed on the target screen.The resolution threshold e can be determined by the resolution of the target screen.And then the new metirics can be obtained by weighting the Quadric Error Metrics(QEM) with the resolution factor which is principally made up of the resolution threshold e and distance from the 3D object to the view point.Redundancy of the model that did not match the resolution of the target screen was removed.The proposed algorithm is suitable for the applications of graphics for the mobile devices.The algorithm is tested on various data sets through experiments and results show its availability.
