This is very interesting indeed, thanks for pointing it out ! I wish I had some time to implement the paper and compare the performance/results to my existing implementation ! Grégory Jaegy -----Message d'origine----- De : Robin Green [mailto:rob...@gm...] Envoyé : lundi 21 septembre 2009 18:59 À : Game Development Algorithms Objet : [Algorithms] New research in SH rotations. I received in the mail this morning a print of a paper from a researcher in "Ambisonics" (the science of multidirectional or spherical sound field recording and playback), Michael Chapman, who claims to have new insight into producing rotation matrices for Spherical Harmonics based on his research into their symmetries: http://ambisonics.iem.at/symposium2009/proceedings/ambisym09-chapman-shsymme tries.pdf/at_download/file Along with this was a reference to a recent 2006 paper on efficient SH rotations from Pinchon et al where they claim to have improved on Kautz, Sloan and Snyder's methods not just in generation but in compact storage as well: http://www.math.univ-toulouse.fr/Archive-MIP/publis/files/06.30.pdf Just in case anyone still cares about efficient rotation of SH functions. - Robin Green. ---------------------------------------------------------------------------- -- Come build with us!
