Hello! There used to be a good implementation of rotation matrix generation code for Real Spherical Harmonics by Don Williamson (donw.co.uk). (The website is still cached on google and the wayback machine: http://web.archive.org/web/20040918193802/http://www.donw.co.uk/) Unfortunately the site is offline right now. Does anybody still have the SH rotation code from there (SHRotation.zip) and could put it online? The demo (and of course, source code) would be quite interesting, too (IOTD by Don Williamson at flipcode: http://www.flipcode.org/cgi-bin/fcarticles.cgi?show=63501). Thanks a lot in advance! Regards, Leonhard

catched in my research folder ;)
