A Web-based Framework for Compressed 3D Objects: Downloading and Rendering

Abstract

This paper is focused on proofing the concept of a web based receiver to download, decode and render 3D objects. It demonstrates the effectiveness in performances when compressed 3D objects are used. It also enlightens the advantages for downloading and rendering in web browsers at different compression environments. It revealed that web-based receiver was useful for downloading, decoding and rendering 3D objects. Downloading time of compressed and uncompressed files was dependent on internet speed while decoding time upon client processing power. The 3D compressed objects took less download/decoding time as compared to 3D uncompressed download time at low (512 Kbps) internet speed. At 2 Mbps, time was not dependent to file sizes. At 10 Mbps, the process was amazingly inversed as times taken by compressed files were more than uncompressed files. This performance evaluation confirmed effectiveness of using compressed 3D objects over uncompressed ones at low speed. The work can also be extended for dynamic 3D objects and animations in future.
