<p>Rhino itself has ApplyDisplacement to bake a displacement map and create a mesh from a model.</p>

<p>Yeah, ZBrush is pretty much the master of this area. Getting the hang of how it works is one of the worst parts, it's GUI and workflow follows very unique roads...<br/>Otherwise it's really brilliant and second to none.</p>
<p>Great you got it working for you!</p>
<p>Cheers,</p>

<p>It took a few days to understand how Displacement works, and is applied to surfaces, in my 45 day Trial of Zbrush. Zbrush certainly has the ability to produce much crisper displacement, along with higher Polygon counts.

<p>Hi Thomas<br/>Thanks for the heads up about Zbrush. This thread is primarily about how to <strong>apply displacement maps to meshes for 3D printing</strong>. I'm also aware there is limit for the amount of polygons allowed per model by those that provide the printing service. So currently its a juggling act between a good looking high quality render, and a mediocre 3d printed product. :(</p>

<p>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. </p>

<p>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. </p>
<p>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. </p>
<p>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.</p>
