Precomputed radiance transfer for X3D based mixed reality applications

Tobias Franke, Yvonne Jung
2008 Proceedings of the 13th international symposium on 3D web technology - Web3D '08  
We present a lightweight framework composed of two extensions to introduce precomputed radiance transfer (PRT) to X3D.  ...  In this paper, we identify the minimal set of components needed for an X3D application to use spherical harmonic based PRT, and discuss how further enhancements to PRT can be implemented, like new basis  ...  This special texture node is used in our paper as one of the building blocks for an X3D-based precomputed radiance transfer application to generate the light vector in the PRT equation.  ...
