Making a unqiue texture on a Brep in Grasshopper

[Edward_Lewis]

Im having trouble trying to make a suitcase with this texture

I have made the shape I want, but how I might create this texture using grasshopper is beyond me.

I also have curves that I created to use as a guide.

Anyone have any ideas of how I might go about this?

install the excellent Nautlius plugin to get access to noises

convert your brep to a dense mesh

use the noise to displace vertices

not entirely sure what’s the right noise for this (maybe @laurent_delrieu could help) , but you get the point

alternatively, try using an image texture. see this post

Displacement map from image

Hi again, I’ve changed the mesh creation using Mesh Plane, to have a regular grid. This has a better aspect in XY plane. Then you could use Smooth Mesh, or convert the mesh to a SubD at the end to have something less kinky. Reducing the amount of points will also help getting somethign smoother. image displacement.gh (1.5 MB)

@adel.albloushi thanks for your comments and example.
Yes noise could be used. This last tool from “Fast Noise Lite” has lots of options. You can use :
OpenSimplex or Perlin. Perlin Seems best.
Frequency must be adapated to the size of the object
In order to have repetitive valley PingPong could (must) be used.
It seem better to have gain to 0 so you will have just ONE frequancy of noises and no octaves (more thiner noise)
Use Ping Pong Strength to augment the number of valleys

I added a CAtmull & Clark subdivision so you can play with coefficient using a low resolution mesh and when happy use a higher subdivision.

Or you can draw curves and use attractors

Can the circuit board effect be created using Grasshopper?

Hello there was a discussion on this subject Some fast test using my Nautilus tool with stepped noise … [image] [image] [image] [image]
