Yes, I can tell you about the core principle of these organics: Create an interesting structure of lines (this is the main work). (Optionally run a resample node over them, if they do not have enough points to make the following nodes create something interesting) Run a "Connect adjacent points" node on that structure, adjust parameters to taste. Next run a strong "Smooth" node over it, again, adjust to taste. Render as strands/hair. Then you listen into yourself what comes up while looking at it. You write that down. Good luck ;-) Cheers, Tom

Sorry, didn't see your reply ;-) This one took something like 16 hours, filling the maximum size of the printer. It's relatively fast to print, since it's only one layer thick with a 0.4mm nozzle. In the middle the structure became rather wobbly and I was amazed that it printed so well until the end. Sadly, the finished lamp doesn't look as cool as the start of the print, since you can no longer see the internal structure, only the folds. So it's live and learn... ;-) Cheers, Tom

Reusing some older Differential Line Growth setups for 3D Printing: Got a Creality Ender 3 Pro for a recent project to create prototypes for several designs we're working on. Updated it quite a bit to be silent and more convenient to use. Last week I finally had some time for my own stuff and tried out some generative things for lampshades. Created the wiggly lines in Houdini, exported as NURBS curves (IGES) to Rhino 7 and did the loft there as NURBS. Sliced the resulting STL in Simplify3D and printed it in glow-in-the-dark (blue) translucent PLA+ Learning and exploring a lot ATM, love to be finally able to bring virtual stuff back into the real world... Fun :-) Cheers, Tom

Hehehe - yeah, that one turned out awesome, still love it too! :-) Cheers, Tom

Hey Wout, thanks a lot! :-) I was away from 3D for a year and only start coming back now, but concentrating more on real-world-design ATM using Rhino - which thankfully now got SubDs... :-) But I did this a while ago in my old Houdini 16.5 and older Redshift, the second image with Octane 4: "Sine Waves" This was a re-visit of my custom "Threader", improving it some more on the way. Cheers, Tom

That was the old workaround, needing an object (probably my own screenshot even ;-) ), but in more recent versions of Redshift you can indeed click into the IPR to set the focus point. Doesn't work well with fiddly thin strands, but is great for product shots etc. Cheers, Tom

IIRC it was a plane that I formed into those ridges and afterwards several bend deformers overlaid. I'm not doing any 3D for a year but making music and creating wood sculptures and other "real" things instead, so can't help you further, my licenses of Houdini and RS actually ran out recently... Cheers, Tom

I wish you all a totally awesome and alive 2020! :-) May your creative juices flow!!! Cheers, Tom

And now for something totally unrelated to Houdini :-) I recently started to finally get into Blender after looking at it for almost 20 years and thinking "it's almost there but..." And now it finally is (for me at least). 2.8x is amazing and especially the modelling part is really great. I love designing with subdivision surfaces & edge weights and missed this since XSI went belly up. Houdini - with everything I love about it - just isn't really made for manual modelling, the tools feel extremely clumsy to me and the whole workflow is weird. The procedural tools are more in the way than helpful and relying on point numbers really isn't a good way to deal with groupings or edge selections in this case. So Blender to the rescue and it really is great in this regard, very fast even at SDS level 3-4 in the viewport, good modes for dealing with working on the cage or the SDS directly, edge creases work very well and are easy to work with. I also like Cycles. It's really fast with my two GPUs and shows great quality - would love to have it in Houdini actually, way more than Karma... ;-) So yeah, if the Houdini modelling tools don't convince you, give it a try. Back and fourth works well with Alembic, and USD is in the works already. VDB too... Some recent fun things: So yeah, Blender 2.81 & Cycles. Cheers, Tom

:-) Thank you very much eetu! Coming from you that means a lot - you have been a great source of knowledge and inspiration on my Houdini journey. :-) Cheers and all the best to everybody for 2020! Tom

"Radiolaria II" I'm currently learning Blender for modelling after totally failing to enjoy manual modelling in Houdini for years now and really love it. Also I found the "Tissue" plugin to be extremely cool for pattern based design. So this is modelled in Blender 2.81, then imported into Houdini 18, further evolved and rendered with Redshift: And with a bit more oooophf: Both are mostly direct renders with Redshifts PostFX & LUTs. Cheers, Tom

Organics: "Radiolaria" Two variations of a scene I created with those fascinating tiny beings in mind... Somehow I was not 100% convinced by the inner structure, so I tried out a more solid version via VDB in the center: Houdini 18, Redshift, Luminar 2018 Cheers, Tom

"Spiraling Sphere II" Re-did this scene with 3Delight as a renderer. It's still in beta but very interesting as a CPU renderer with perfectly integrated cloud rendering. Houdini 18, 3Delight, Luminar 2018. Cheers, Tom

"Spiraling Thing" Worked a bit more on my threader tool... Houdini 18, Redshift, Luminar 2018 Cheers, Tom

"Rumis Field" "Out beyond ideas of wrongdoing and rightdoing there is a field. I'll meet you there." Rumi One of my favourite quotes ever... And an organics version: Both created with a custom solver in Houdini 17.5 & rendered in Redshift for High-Rez printing at 18000x12000 (https://www.artstation.com/thomashelzle/prints). Cheers, Tom
