I ended up un-hiding the DOP-POP stuff that was in the beta but hidden in the final release, and building Scatter qL SOP. We're talking about tens of millions of points on a single CPU. Anyway, I was in a situation where I had to build my emission points in SOP using Scatter, then doing the sim in POPs. The way it's usually done is by creating some volume fluid/smoke sim and advecting lots of particles with the velocity volumes. Right now I'm working on some underwater-ink effects. The last two major additions to qLib are Scatter qL SOP and Ray qL SOP – they're a bit feature-incomplete compared to the originals, but they are multithreaded – if you're working with tens of millions of particles, using all CPUs does matter. Apart from sharing all the stuff we're very selfish people. We use this stuff all the time, so we want to make sure our own dog food tastes proper. Making sure the quality is OK is also very good for us in the long run. This library is basically a “side effect” (heh heh) of us working with Houdini (we realized we need to build an asset library anyway, so why not do it properly – and while we're at it, why not share with others). We believe that Houdini has a wonderful user community with lots of clever and helpful member, so we hope that a project like qLib can focus that knowledge and wisdom into tools thus making every Houdini user’s life a little bit better. Now we want to invite all of you to test, to comment, to criticize, to report bugs, to help us to write better docs, to fix tools that doesn’t work as intended, to share your ideas and to share your assets that you find useful and that you have no problem with others finding it useful too. Later we wanted version control and decided to embrace the open source development model, so we put the whole library up to github and made it public. When we started qLib we wanted to have a library that is documented, and actively developed and maintained. qLib is a library of more than a hundred more or less simple tools that we built during and beside production work as Houdini artists. Dear fellow Houdinistas! We are pleased to announce that after more than two years of tinkering, qLib - our open source asset library for Houdini - has reached version 0.1.
