Hey all, I'm using curl noise to make these coral-like structures. I figured out a way to make these structures grow generally upward, but I haven't figured out how to make the grow upward AND also follow a specific shape as they grow. Does anyone know how to do this? See attached images. Here is the HIP FILE: CoralGrowth-FlowAlongSurface-Interesting1.hipnc Here are some files that hopefully give more clarity around what I'm trying to do.

Ahoy there!!! A quick question... I'm writing VEX noise functions but is a bit confused with Curl Noise functions. It's not like that I didnt get it. Of course I get it but is stuck in this weird functions in voplib.h. Here's what I'm stuck with.... Down below is the Code. why is xDiffNoise yDiffNoise and zDiffNoise there anyways. I couldnt find a function that's making use of it. Maybe I'm missing some. But please somebody explain it to me. Just to say... I'm writing a Curl Vex Function with all the Noise options. Thanks. noisevec = onoise(pos*freq - offset, turb, rough, atten) * amp; xDiffNoise = onoise(xDiff*freq - offset, turb, rough, atten) * amp; yDiffNoise = onoise(yDiff*freq - offset, turb, rough, atten) * amp; zDiffNoise = onoise(zDiff*freq - offset, turb, rough, atten) * amp;

HI Does anyone know how to make an offset mesh, to create thickness?? Also, does anyone know how to make the exterior surface of my mesh like the image? I have uploaded my hip file. scene3.hipnc

Hi guys, I have imported a very simple obj from 3ds max and I am trying to apply a curl noise effect to the surface of it... I have played around with the amplitude etc but nothing seems to create very long lines and it looks pretty awful.... (I have attached an image...) When really I want to be getting an effect like the image below my image.... does anyone know why this may be? I am wondering if it is a scale issue perhaps? I want it to stick quite close to the geometry which has long trails but does flick off the geometry every now and then like my reference image.... Any help would be great! Thanks Matty

how to avoid curl noise trails end into point
cokopoboso posted a topic in General Houdini Questions
Hi this is a newer to Houdini, as the topic suggested, how can i avoid my curl noise trails ending in a point ? i want them keep flowing along the surface, is it possible? Thanks! curlnoise_trails.hipnc

Is there a way to freeze the transforms of a curl noise in a DOP popvop? I am running a point sim and my source emitter object is animated and rotated in world space. When the points emit, the curl noise added to the point position slides. I'm really not sure what to do in the popvop to freeze the curl noise. Ive tried using a popforce, however the curl noise does not seem to create the same shapes that the popvop does. Thanks in advance.
