I’d think via email is best really, see address above… thank you in advance!

How should we send that information over? In the comments via email?

Comment on Upcoming: The Winged-Edge mesh class by Robert

I’m looking forward to the new release. I’m new at processing and new at 3D scripting. I’m learning a lot from you, and your toxilibs are extremely valuable to me (though, I can’t use most of them yet). I’m using the libs to design 3d items to be printed at Shapeways. I can’t thank you enough for your generosity…sharing your hard work…it’s awsome.

[...] Toxi recently posted about a library called simultis which explores this DLA process with some amazing looking results: http://toxiclibs.org/2010/02/new-package-simutils/ [...]

Hey, thanks guys & sorry for slow reply. There’re no courses planned in the US so far, but who knows. It’s good to know there’s growing interest in such things and that’s a start :) As for online courses, also not really. However, I’m publishing all source code of all project of each workshop on my learn wiki and will post an addendum of the Olhares workshop in the next few days… We build quite a few small projects this last week and more importantly they provide a great resource for all those struggling to understand how to use the various libraries in relation to each other and also provide an introduction to OOP in the context of small(ish) projects. So watch this space!

No need for that (in case of the AABB style clipping as above). The volumetric space itself is a cubic grid and what you’re seeing is simply the full space and the fact that he didn’t close the sides of the volume. You can also see the effect in the BoxFluid demo which comes with the libraries, only there I chose to close the sides by default (can be toggled on/off though). Online demo of that is here: http://www.openprocessing.org/visuals/?visualID=9673

As for clipping using a freely defined plane or other form: that’s something still outstanding (unfortunately), but since the resulting mesh is a standard triangle mesh you could at least do a simple culling of entire polygons by using the classifyPoint() method of the Plane class. If one (or all) vertices of a triangle are on the “wrong” side of the plane, simply don’t render it (or build a new mesh which only contains the triangles which are valid). That approach will create fuzzy borders for non-axis-aligned planes, but is better than nothing. If you want to spend more effort you can then also use intersectsRay() from triangle vertices outside to find the correct point on the clipping plane…

I’m curious, what method(s) would be a starting point for clipping the volume? Here it looks like a simple AABB is doing the clipping. intersectsRay?

Very cool though.

Have you taken in account magnetic field influence on the grown and many centers dla
