Wireframe Tendrils

[ruchitinfushion]

Hi, How can i  create effect like this Wireframe Tendrils in Houdini ?

And is it possible to transfer poly texture color to wireframe??

You can create the effect by advecting points through some perlin noise.

The example in the link uses a rgb perlin noise image (http://charliehoey.com/threejs-demos/textures/rgb-perlin-seamless-512.png)

 

You can use this function to sample the image:

Hi

 

looking great, can you pls share hip file???

 

thank you.

Here is the hip file. Most of the code is copied from his glsl shader.

You need to download the rgb noise image and put in the same folder as the hip file.

Thanks for the example file Simon. It renders very fast using the OpenGL rop.

I had a quick go at this too, just using vops rather than particles. Really good way to visualise the different noise types, see their ranges, how they animate, what they might be suited for. That three.js demo was a really nice find, thanks for sharing!
