Houdini Tutorial: Space Filling Cable Generator

[@alexrumsey3946]

Such a well structured tutorial, so useful to see the thought process and the complexity build, rather than just laying down all the nodes in order and trying to explain the future reasons for each node. It's nice to see the simplest version of the thing first.

Thank You very much, Chris!

This is so cool. Thank you!

Always, Next level stuff.

The expresion: nearpoint(1, v@P, chf("Radius")) != -1

[@towhidurrahman4686]

Great!! But missed the rendering part.

[@6rilllir6]

thanks for the video. At 14:34 how come you set the sweep node radius to a fix value (0.5) and the cables are of different radius ? Is the radius parameter of the sweep a factor of the pscale automatically ?

[@gh0st_h4rdware27]

Not sure I’ve understood correctly, the sweep node is reading the pscale attribute

[@1974elky]

Yes. If you follow this simple setup in a geo node, you can see how the two interact. line -> point wrangle (define pscale) -> sweep The sweep node uses the pscale as a multiplier

[@6rilllir6]

@@1974elky good idea to test it out ! I didn't because the info when hovering the mouse over the radius field is not talking about it being a factor... anyway, good to know.

Just curious - what is hard for Houdini to do, is there thing that are inherently imposible or hard to do here?

[@jabelsjabels]

I don't think it's really designed for traditional 3D modeling. Like I wouldn't use it to build something like a human head from reference images like you would in Blender for example. It really doesn't have those kind of quick shortcut-key modeling tools as far as I know. Because everything is non-destructive and node-based, you'd need a new node for each edge loop you wanted to cut, or each extrude operation or whatever. I've only used it for about a year now though, so that functionality might be in there and I just haven't found it yet!

@@jabelsjabels So, only for abstract procedural stuff?

[@somerandomlittlechannel7860]

@@bbrother92 Doesn't have to be abstract, but procedural yes. Like you could use it to build entire cities e.g. Matrix Awakens (they used Houdini for that)

@@somerandomlittlechannel7860 is posible to create procedural humanoid monster, you know organic staff?

[@MarcouscousAurelius]

as a beginner I was following fine until ... I assume intentionally overly complicated setup for randomizing cable thickness, there must be an easier way,, right? I mean its cool to show the hard way for learning purpose but viewer would also benefit from learning the easiest route as well.

[@JamesFriggens]

I think it would have been easier to use an attribute randomize node after the "smooth1" node within the for each loop. And then using a channel reference to read in the iterationnum attribute for the seed parameter
