]]> Comment on Salmorejo means food in summer by Pablo http://castano.ludicon.com/blog/2009/07/10/salmorejo-means-food-in-summer/comment-page-1/#comment-31525 Pablo Mon, 01 Mar 2010 01:42:03 +0000 http://castano.ludicon.com/blog/?p=1581#comment-31525 Saludos desde españa, no tengo ni idea de como he conseguido este blog, pero creo que ha sido gracias a the witness. Me he sorprendido de que realmente conozcas y aprecies el Salmorejo, que siendo yo de Andalucía, y específicamente de Huelva, conozco a la perfección. Un plato frio, que debe comerse preferiblemente en Verano, y que es una delicia para el paladar. La foto tiene una pinta espectacular, solo que el jamón siempre se sirve por encima del huevo, y el huevo rallado en laminas muy finas. Pero a quien diablos le importa... EXCELENTE!!! PD. Estamos muy interesados en más noticias acerca de The Witness, y te deseo la mejor de las suertes en este nuevo proyecto... Grettings from Spain.

We are finally doing something interesting with parameterizations in our current project and I hope we will be able to release that at some point. I didn't avoid doubles for any particularly good reason, other than I tend to avoid them unless it proves to be necessary, but maybe this is one of those cases. On the other side I did use Kahan sums to compute dot products since in some cases I noticed that affected the output. Maybe switching to doubles would have achieved the same results. Will do!

Cheers, -- Bruno P.S. I've seen that you are using single precision floating point number, did you try with double precision ? From my own experience, it is faster for mesh parameterization (due to numerical precision and convergence speed of conjugate gradient). Hi Ignacio,
Thank you very much for the link to OpenNL, please tell me when
your own package is available, I’ll add a link.
