  1. Differential curve growth

    Very cool stuff here, guys! I learned a lot.
  2. Controlling Curl Noise Direction along a surface

    Wow. That is an insanely helpful resource. As a beginner in this software, that is awesome. Thank you so much!!!
  3. 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.
  4. Hey guys. First post here. Very new to Houdini. Does anyone know how to do this effect? Could you tell me how? More specifically, it looks like a shockwave that radiates outward from a fixed point....but the shockwave isn't totally uniform. As it radiates outward, it creates little randomized circles and shapes. Please note, I'm talking about the opening shot with the mint-green background. Not the thumbnail of the video. See video here: If you guys could point me to tutorials (or maybe it's a combination of several different tutorials), that would be really awesome. I would do it myself, but I don't know what search keywords to use to find out how to make a similar effect. I've only been using the program for a few weeks! Edit: I found an entagma tutorial entitled "differential line growth". This is pretty close to what I want to do. The main difference is that I want it to radiate outwards from a fixed point, and I need it to be happening on actual geometry...this tutorial seems to be just lines. I'm going to go through the tutorial right now and see if I can figure it out myself. If I do, I'll be sure to share my findings.
