Predictive Modeling of User Interaction Patterns for 3D Mesh Streaming

3D Streaming – An Overview

3D streaming (Cheng, Ooi, Mondet, Grigoras, & Morin, 2007; Tang, Z., Guo, & Prabhakaran, 2011; Cheng, Liu, & Ooi, 2009; De Paor & Whitmeyer, 2011) is the process of delivering 3D content in real-time for the users over a network. 3D streaming is carried in such a way that the interactivity and visual qualities of content may match as closely as if they were stored locally. The main resource bottleneck here is usually assumed to be the bandwidth and not rendering or processing power of the clients (Teler, 2001). To effectively utilize the bandwidth, various approaches are followed out of which the following two categories are considered to be highly dominant strategies.

  Model Simplification;

Model Simplification Approaches

Approaches for simplification of the 3D model in other words polygon reduction techniques are the one of the dominant strategies used in 3D streaming by many researchers. The following section discusses the predominantly used polygon reduction techniques in 3D streaming by exploiting user perception. Also, it discusses the type of network environment considered for streaming.
