Hi Folks!
I'd like to submit my least squares plugin. Right now it is using a very simple library i found in Sf.net. Is K-3D using any linear algebra library? Cheers!

Doesn't boost have some linear algebra functionality?

As far as I know there is no lib in K-3D for it already, but if Evan is correct in Boost having it, maybe that should be used instead. At least it might be a good idea to investigate. /Anders ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

But useful for the beginning. http://www.google.com/search?q=SimpleNumericalLibrary.tar.gz&ie=utf-8&oe=utf-8&aq=t&rls=com.ubuntu:en-US:unofficial&client=firefox-a Seems it's gone from sf.net there are mirrors only Thank for the answer. I guess i'll use boost. Cheers! Joaquín ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

The QuadrilateralRemeshing plugin has a dependency on SuperLU. PGPRemesh has a dependency on GMM. In fact, there is a copy of GMM in the k3dsdk/gmm directory, which in hindsight was a mistake, so don't plan on it staying there. My suggestion (applies to anyone) would be: * If Boost.ublas meets your needs, use it - since Boost is already a required dependency for K-3D, it's guaranteed to be there. It also benefits from all the good Boost design and coding practices that we actively embrace. * If Boost.ublas doesn't meet your needs, use whatever you want, but plan on making it an optional dependency, setting up a FindFoo macro in CMake, etc. Cheers, Tim -- Timothy M.
