Creating 3D texture based on Bitmap

[jessesn (Jessesn Chen)]

In this video will introduce how to use ShapeMap to create 3D texture based on an bitmap,

• You should to install the latest Rhino 8
• You need to install ShapeMap for Rhino 8
• Please download the .gh files demonstrated in this video if you want to give it a try following this video

Fading pattern
pattern gh
I’m working on a project and I want to blur the edges but I couldn’t do it
By the way, I watched it, but I could not apply it to my work

@Mehraneftekari Just fyi, any question please reply here.

@jessesn Hi,
I was trying your new example with textures applied to my starting surface. As you can see from the screenshot, when the “RD” option is not connected, I can see the height of the object. However, if I connect it to “Image2mesh”, I can’t see the image on the target surface.

You need set a valid Doman value to Range,

Image2Mesh_Range.gh (2.4 MB)

BTW，you need to know how to set the Range, for current setting 2 to 5

• The texture height within the range of 0 to 2 from the edge is 0.
• The texture height in the range from 2 to 5 gradually increases from 0 to 5 (determined by the Height value).
• For distances from the edge greater than 5, the texture height is equal to the Height value.

Thank you for the help, one last thing: in case I want to move the coordinates in x and y, is it possible to do it? Because, as you can see, the texture is not aligned with the axis of symmetry.

Sure, you can adjust it via Image Samper

I was trying to follow the example from the tutorial. I have a problem when I load my 3D file on subd as shown in the picture. How can I explode the shoe into various parts? The example model allows me to do this, but I can’t figure out how to do it with my subd model. In my 3D model, I simply applied a quad remesh with subd. Do I need to mark the sole line in some way?

Please give it a try with Split and EdgeLoop option ?

Hi Jessesn, I’ve been stuck on a problem for a long time. I created a closed polysurface and need to generate textures on one of its faces, as shown in the figure below.

Textures generated via ShapeMap are mesh geometry. The high-density textured mesh creates topological inconsistencies between the textured face and the remaining surfaces. Is there a way to stitch everything into a single watertight closed mesh without converting any geometry to NURBS surfaces? My final output is for 3D printing.

(Converting such a huge number of faces into NURBS would also take an extremely long time, anyway.)

You’re right — converting a high-poly SubD to NURBS does take a while (especially with the Packed option on). From your screenshot, it looks like the texture is surrounded by planar curves. You can try extracting those edges and extruding them into new mesh geometry to build a watertight closed mesh. If you get stuck, feel free to share your .gh file — that way we can take a closer look.

Hello @jessesn I have been able to recreate your video and apply the texture from a bitmap to the sole of the shoe. I would like to exchange my model (in this case a plain sphere) to a brep or subD that is valid for this script? It seems whatever I try to use is the shapesolver is not able to process it. ( I will eventually want to add a bark texture to a door I need to cut out.)

Since ShapeMap doesn’t support closed objects, you could divide this closed sphere into two open halves and give it another try.
