Configurable instances of 3D models for declarative 3D in the web

Abstract

Figure 1: A Virtual World scene featuring several instances of the same robot character, configured to have individual poses and colors. AbstractThe Declarative 3D for the Web initiative by the W3C [W3C 2011] connects 3D content to the Web document, intertwining it with other Web technologies known to millions of Web developers. The goal is to make 3D on the Web more accessible compared to lowlevel APIs such as WebGL. However, all proposals for Declarative 3D for the Web are missing an essential feature: configurable instances of structured 3D models. While instance mechanisms do exist, they all have limited capabilities to configure instances individually.In this paper we present a new approach for configurable instances of 3D models that is integrated into XML3D. Our approach comes with a compact interface, a powerful extension mechanism to handle configurations, and an efficient data structures for efficient instancing. We demonstrate how our instance mechanism simplifies the handling of 3D models in several different application areas, including Virtual Worlds, and provide several performance results for the instancing process.

Real-Time Large Crowd Rendering with Efficient Character and Instance Management on GPU

“…Ashraf and Zhou [46] used a hardware-accelerated method through programmable shaders to animated crowds. Klein et al [47] presented an approach to render configurable instances of 3D characters for the web. They improved XML3D to store 3D content in a more efficient way in order to support an instancing-based rendering mechanism.…”

Crowd simulation rendering for web

“…But, regardless of the fact that the possibilities of web-based simulations are subject of interest for more than a decade [Kuljis and Paul 2001], just a few works have dealt with crowds in the limited web-browser environment [Bruzzone and Signorile 1999;Klein et al 2014]. …”
