VEX101 - Generating Curl Noise
Added 2018-04-17 08:07:30 +0000 UTCAh! What can be more relaxing than having our copies transformed by everyone's favorite noise - the curl noise? This is the same technique we used to create this course's preview image.
After this one we'll look into how we can combine simple VEX with a bit of math to visualize acoustic patterns.

Cool! Anyway to have them loop?

2020-08-12 06:32:04 +0000 UTCGreat series, thank you for such high quality content. I don't know how to thank you enough. I have a simple question that may not have a simple answer. In the version that you've created for the Intro graphics I notice that your rectangles animated with the curl noise do not intersect each other, are you perhaps combining the attribute wrangle with rigid bodies?

2020-08-12 01:57:35 +0000 UTCAmazing as usual. Maybe for performance and Redshift stylesheet could be a good option using Instance node instead of "copytopoints"? I tried and it works good.

2019-09-20 08:34:04 +0000 UTCHi guys — Great tutorial. One question though: I'm not quite sure I understand how the curl noise generates the result it does when we set it to affect the template point's position v@P and not rotation / orientation. The point's stay where they are, so how come the normals rotate? All the best, Andreas

2019-07-11 06:58:25 +0000 UTCHi Juan, typically I'd stay inside of Houdini for those kinds of setups. I think what might work could be using a convert-SOP before exporting to alembic, so you'll convert the packed&instanced primitives into geometry. Not sure though - gonna check as soon as I'm back at my workstation. Cheers, Mo

2018-10-18 08:44:01 +0000 UTChey guys so how can i pack this into 1 animated alembic object, when i export as alembic i get each object separated its a nightmare for c4d, runs so fast in houdini its a joke. i´ve tried alembic rop but i can´t seem to get all to be 1 animated object. How would i go about this ?

2018-04-24 00:39:37 +0000 UTCshort and sweet! had a lot of fun using the curl noise function, especially when changing the copies color and pscale over time. made me very happy. thank you!
