How do I convert the Blender texturing techniques discussed in the link below into geometry so that I can print them on a 3D printer, and are there any limitations that I should be aware of?
If you apply the texture to a "displace" modifier, you can apply this modifier and have it affect your geometry permanently and 3D-printable. (The "displacement" from the material editor will not work for this, the texture needs to be used by the "displace" modifier.)
There are only two things you should be aware of:
- if you have any other modifiers (such as subdivision), you need to apply them before you apply the displace
- obviously, the effect of your displace-modifier should be strong enough to be actually resolvable by your 3D printer
