Is there a way to control the flow of scatter points using curves?

Hello, I'm trying to create a signed distance with curves or a vector file. But I'm having trouble figuring out how to go from one shape to another... Essentially I'm trying to be able to blend from a complicated shape (in the center) to a simple rectangle on the exterior. attached is a simple...

Hi everyone, I am looking for a good approach to generating curves that follow the curvature of a mesh. The goal is to generate line art in 3D, so not in post-process. First Approach My first attempt was based on vertex normal to find the lines, but if I push too far the sharp edge detecti...

Hello. Help me, please get rid of flickering on animated geometry. I have curves generated with "find shortest path". I'm tried interpolate, but still error

Is it possible to use a curve to influence the vertices on a mesh like this grid?

I imported my xgen descriptions as alembic curves to houdini and i'm trying to use these curves for the simulation. I did select the Use external Geometry in the guide groom node's basic tab but they are not doing what i want them to do. I basically want to simulate this curves from my t pose charac...

Hi Guys, I'm stuck doing this stuff, I would like to make a DNA based on fiber/curves like in the picture The 2 branchs and every step in the middle are noisy fiber.. I getted the DNA but can't get the way for the middle steps.. Any help would be appreciate. Thank you...

I'm snapping a path along a terrain and then using that path in a sweep node as a backbone curve to generate a wall. The problem I'm running into is that the sweep is following the tangent of the terrain normals and creates a warped look in the corners that's accentuated with increased height. I t...

I have a 1 object that consists of a ~1000 closed curves/splines (same ammount of primitives), i want to generate particles on each curve and move those particles along them, but each particle stays on that same curve it has been generated onto. i started with popnet with a force an...

Hi, So, I following this tutorial and got stuck at the actual web shooting part which happens at 43:00. He did it with vops, is it possible to apply the same principle to achieve it with vex? Maybe by moving it back to rest position? I tried it with a carve node but the transformation isn't as...

Hi, Anyone knows a good way to deform groom using sim curves? as guidegroom deform doesn`t seem to work for me and pointdeform has some other issues. Do I really have to sim low res curves and then apply hairgen for full res? Problem is that i have my groom done already and want to s...

Hi, I've created a basic picket fence setup. Each picket is positioned on a ground fence segment based on its width, as well as the segment's length. There's a curve_height that I want each individual picket to extend to. I'm currently stuck as to which part of the for-loop to...

Hi guys, may I ask for a quick way of converting geo tubes into straight splines? ATM I'm abusing the fracture tools to generate single constraints withing the center of mass and a join afterwards. Kinda works but wth some flaws. A few lines show discontinuities/breakups. Disabling "onl...

Hey all, I've been having an issue figuring out the best way to make panels move along a curve - constrained to each other. Like chains, tank treads, sectional garage doors, etc. I've attached an image of the issue, the black dots would be wheels on a rail. It looks like the chain sop uses curv...

Hello everyone, I am new to Houdini and was wondering how to solve an issue regarding the overlapping or intersection of curves. As you can see in the supplied images the curves become messy and extremely close to one another. Is there a method in order to be able to either delete curves...

Hi guys, I'm looking a way to refine my trace node import (iges). Is there a way to keep point only at angle? to keep it clean when extruding.. Thank you for you help.

Hey Guys! I'm trying to find a way to interact Vellum Grains with curves using Vellum Hair/Cloth. Attached you can find a test scene where you can see an simple example. In this example there is a switch node with three different setups: 1) Hair 2) Grains 3) Cloth M...

Hey everyone I am making a road system that dynamically deforms the terrain and for the most part it works great however every individual street is its own curve then merged and fused together. The problem is I will end up with 100's of curves and if I want to go back and adjust a point I have to go...

Hi everyone, I'm trying to bake to texture a bunch of curves running along a surface. I'm wondering if someone can suggest a more effective solution than the rough one I've already figured it out. I basically made a color attribute transfer form the curves to a very high subdivided mesh, but th...

I've got a curve that I want to attach to a piece of geometry. The connection should be smooth, more like roots of a tree, and not with a hard angle. How can I make my curve follow the shape of the surface I want it to connect to for a bit? Everything I came up with was either not really...

I'm running into an issue. I'm using the convert node to change my wires to NURBS. However, when I render these out it renders them as if the conversion hasn't happened. Is there a good reason as to why this is happening?
