An interpolation technique has been identified for resampling the measured data, and an initial implementation has been produced. Work continues on improving this technique and software so it may be employed in a streamlined process for reducing BSDF measurements to a usable form and distributed as variable-resolution XML data. This data may then be employed by lighting simulation software to model complex fenestration systems.</p>1 aWard, Gregory, J.  uhttps://facades.lbl.gov/publications/conditioning-anisotropic-bsdf
