A pipeline for the creation of progressively rendered web 3D scenes

Abstract

We present an end-to-end pipeline for the export of 3D scenes from content creaton tools to a real-tme rendering engine in an embeddable web-page, including a novel system for compression/decompression of textured polygonal meshes. We show that the compression/decompression outperforms the best state-of-the-art non-progressive alternatve, especially as bandwidth increases, showing that web-specifc techniques should consider the whole user pipeline. Our pipeline also includes progressivity, which is paramount for a good interactve user experience, and permits full user interacton with lower resoluton versions of the 3D scenes, while progressively higher resoluton data is downloaded. Finally, we discuss how our method may be used in the future to facilitate the transfer of animated meshes.
