Feature lines extraction for remote rendering on point model

  • 121 Accesses

Abstract

In this paper, we propose a method to extract feature lines on point model via an implicit fitting process at various scales. Based on these feature lines, we present a feature-based remote rendering scheme to interactively display large-scale point models on mobile devices over a low-bandwidth wireless network. By quickly loading and rendering the feature-line representations, users can well capture the general shape and main features of a model. Further a hybrid rendering of point and feature line helps to interactively display regions of interest. If with a powerful rendering capability, clients can also approximately reconstruct the model guided by the features. Experiments show that a small amount of feature lines can hold the ruling perceptual details and deliver a good visual impression.
