How is this surface made?

Hi,

Can anyone advice me what to use to create this soft silk fabric like surface? Can I use Autodesk Mudbox? Any tutorials online perhaps?

Hi Diana,

There are multiple approaches to this - in plain rhino without plug-ins maybe use height field provided you have an image to work off of?

An option, mudbox, yes, or ZBrush (better) - though even with freeware blender you can use an image with depth information and pull off a relief.

I have used height field in rhino for a while but I only get rounded bumps nothing close to the above images.
Here is my drawing:

and this is what I get (which is no where close to what I am trying to achieve like the img on my previous post)

Yes I have played around with the numbers when it asks you after you insert the image. Still no success

maybe play with the height field settings a bit more for resolution? Results can also be influenced by the resolution of the image itself.

Example:
work your image a bit more in photoshop (invert colors if you need):

use mesh



…maybe closer to what you want, you can smooth the mesh afterwards - I grabbed a screen capture of your pattern.

Looking at your iso curves, you need much more control points. Use a very dense surface or mesh.

Hello
you could use smoke plugin.

Thank you where can I find this plugin?

Thank you so much!!! This was very helpful! :heart_eyes::grinning:
How would you smooth the mesh afterwards? By rebuilding it?

Check out weaverbird, in this case Laplacian Smoothing will be helpful. http://www.giuliopiacentino.com/weaverbird/

…not entirely sure if smoke plug-in is still around…also it appears you’re wanting to stick to Rhino only.

Alternatively - if you do choose grasshopper - Digital Substance had a twirl script that may be of help

find the ‘swirl mesh’ example here:

Not really I do want to transfer this model to Mudbox and continue working on it there however I find it a bit hard with the exporting part back and forth

Also I am not looking for twirls but rather translating my painting into these shapes (the first img I posted on this topic) to cnc into a block both cncd from top and bottom.
Thank you for the links

got you, probably better to stick to mudbox then, and avoid import/export hassle - you can sculpt a mesh using an image as displacement map

Hi Michael,

Which param would show the result as in what do I plugg output to to see how the surface would smoothen based on the sliders?

Hover over inputs for description, in this case L. Also, you will get nicer results if you blur the black parts of your image with a bit of a gaussian blur in photoshop so the jump from white to black isn’t so sharp.

Ah thanks the gaussian blur rlly helped.
Not sure what you mean about the description of L … I know its the subdivision of the surface…
So in conlusuion I dont need to plugg O into anything?

I’m saying the descriptions will tell you what the input is for.

Neither of those look like they were made from a heightfield, they were just brute-force modeled, likely using some kind of mesh sculpting tool.

Hmm what are you implying? Should I not approach it this way

I would use a polygon modeler with Rhino. That way you can subdivide the surfaces in a program like Silo, Blender or Z Brush. Then export back into Rhino.

Diana turn off the preview of your input mesh (mesh component) so you are able to see the smoothed mesh (wbLaplace) by itself and not overlaid with the mesh from rhino
