algorithmic modeling for Rhino
How can I apply a displacement maps to Meshes for 3D printing?
example: I want to create an embossed pattern that wraps around the surface of a simple wine glass, using a displacement map.
Then save the wine glass with the embossed pattern geometry for 3D printing. How would I do that in GH?
The following pic shows the process in Maya.Note: the traditional use of Displacement maps is for rendering, such as the pic of the Head, where it is used as an opacity map.
The entire ZBrush interface is shown in a single tall image, here:
Hi Kim - since you are planning on using 3D printing to make your design I'd like to suggest an alternative approach: Make the basic part (the glass in your case) one part, and then make the bumps (or whatever other decoration you want) as a separate part. Then, when you print, you can combine the 2 parts and they will print as one.
A second benefit of this approach is that you can print with 2 different colors and/or type of filaments. (Of course this assumes your printer has dual extruders.) So your basic shape (the glass) could be one color (perhaps transparent) and the decorations could be a totally different (and perhaps non-transparent) color.
The 2 photos show a small table lamp that has 2 such parts; the images are from Simplify3D which does a nice job of handling 2-color prints.
Hi Birk - thanks for your suggestion. :)
Rhino itself has ApplyDisplacement to bake a displacement map and create a mesh from a model.
Along with the ability to edit maps, it may be useful.
