Houdini releases always seem to have so many great features behind the headlines that become day to day workhorses.
I came across the improvements in the Smooth node as I was exploring the new 'Compiled Block SOP' feature with ome old VEX snippets that Shawn Lipowski shared as part of his VEX course a few years back (code for Laplacian/Taubin smoothing). The VEX method was just as good as the new Smoothing node in H16 but it was slow because it had to be iterated a fair number of times via a ForEach and the old ForEach wasn't multithreaded. The new 'Compiled SOP Block' solved that problem but then I discover Houdini ships with a C++ compiled Smoothing node that's even faster! At least I learnt a few things about the new 'Compiled SOP Block' so it wasn't a complete waste of time. :) On 28 February 2017 at 15:28, Ed Schiffer <[email protected]> wrote: > this is brilliant... thanks for sharing. > I still haven't checked this one. it's so much to see!! > > > > On 28 February 2017 at 10:31, Jonathan Moore <[email protected]> > wrote: > >> Loving the new H16 Smooth node.
