Volume Trails in Houdini

Volume trails are a pretty cool tool in Houdini which can create abstract forms, but can also be controlled to build a very specific shape using vector volumes. In this tutorial we set up our custom vector volume using the tangents of a curve mix it with a 3D noise and calculate a cross product to build an interesting vortex structure.

Nice tutorial! Clear & level speech pattern, concise information, and no fluff = well done!

[@mathef]

Absolutely amazing tutorial and very well explained. Thank you very much! :)

[@violentbadger6401]

Fantastic tutorial! Was great to hear how passionate you are! I'm using this for particles and it's really fun and effecient also!

[@STEALTH42UA]

Amazing! Houdini amazes me every day!

[@reecpj]

Awesome tutorial! Learned quite a few tricks from it, thanks!

[@northernmotion090]

Awesome tutorial, thanks! I'm only just beginning with Houdini, so I'm plowing through tuts right now... this one was great!

[@KikabomProductions]

Listen man this tutorial is insane I am learning houdini now and WOW this shows so many tools and how you can use them to create very nice effects!
Thank you very much for your time!

[@rupeshpatil8449]

It's really awesome. Thanks for sharing this with us. Nice.

[@randyjackson5535]

Very well done! Thank you!

[@xXSpaceCowsXx]

To anyone wondering why you cant see your volume, make sure your naming of velocity is changed to vel instead

[@rexrr1607]

Soooo helpful!!! great tutorial!!! Thanks!!!

[@tignas7]

Thanks Thanks Thanks!!!!
very very informative tutorial!

[@cabelnam]

Thanks for this! absolutely awesome stuff for my beginning)) would like to see more tuts about particle advection and different fields creation.

Thanks Man. keep doing it.

[@aryansachdeva5060]

Amazing Tutorial

[@davidharford3873]

Great tutorial! Are you Atom on the odforce forums?
Roughly how long did it take you to be able to think/prototype/create this in Houdini? I am interested in your learning methods.

[@khedkarsanto]

very well explained

[@maayaa77]

Dude Your a F%$#@N Legend !

[@VietnamFoodBoy]

Thanks

[@dtphongla]

thanks, i love your clip. we nee more tutorials.

[@TheLukazzz911]

grat vid, cheers

[@xxxAzraelxxx]

Thanks a lot for your tutorial, do you know how i can transform this to smoke? :)

[@Screamer]

Now I know a reason to complete highschool math.

[@Bloemhoofd]

It's been a while since this tutorial, so maybe you know this already. But instead in the wrangle node where you reverse the tangent, you can simplify from "v@tangent = @tangent * -1" to "v@tangent *= -1"

[@SupSupa10]

Many people commented here ( include me ) that using 16.5 is not working with this tutorial from step " creating Volum vop with input1 and input 2 and nothing happen " . Can you tell us some solution, please ?

[@gegwork]

@@SupSupa10 Inside volume vop, in bind, be sure the name is velocity

[@hyeokyoung]

I really love this tutorial and his way of teaching. Anyone know who he is? I want some more tutorials from him! :D

[@chachahu9433]

This digital artist named Simon Fiedler.

[@hyeokyoung]

Thanks!

[@abderrahmanewalidaissani909]

Great tutorial, Very helpfull. I'm just starting with houdini. I'd like to know if there's a possibility to upload data from matlab to houdini. The idea is to bring a velocity vector matrix and do simulation with it? Thanks!

[@krejcivaclav]

If anyone is wondering, here is a solution for Houdini 17 for the first step. In the Volume VOP, change the Bind export name to "volume_velocity". For previous version, you may want to use "vel". You don´t actually need volume VOP, as there is a dedicated node - Volume Velocity, where you can enable Curl Noise as well.

[@zorbutanofalis]

I want to make a custom velocity that follows the geometry of a specific object. How might I do this? Thank you!

[@TrainwreckNZ]

Once I connect the curl noise node to the bind export, nothing happens. What have I missed?

[@MartinZeme]

Same here!

[@manvredo]

Same here... have someone an answer... I think its about the new version...? Periodicnoise is working!

[@chachahu9433]

check the bind parm's name and type, which should be "velocity" for name and "vector" for type.

[@SupSupa10]

I connect volume pop exactly like in tutorial and nothing happen

[@lyndajones1133]

moving your mouse around the screen is a tad distracting rather than just landing it on the parameter you talk about changing

[@SupSupa10]

Nexttime please record at least in FULLHD. I can't read clearly what you code.
