Is there displacement mapping in Blender (2.28a)?
I’ve also tried Tuhopuu-Blender 2.25 (2003-07-06), but I didn’t find such a feature there either.
You mean bump mapping? Just click on the ‘nor’ button on the far right in materials. Oh and crank up the slider that determines the relative values right next to it.
Displacement mapping is not implemented yet, but poeple are working on python scripts.
https://blenderartists.org/forum/viewtopic.php?t=13135&highlight=displacement
Without scripts you can only displace a grid. Give it a texture and in edit mode press noise, this will displace in one axis according to the texture.
Then there are scripts which will turn this grid to different shapes (sphere, torus, cylinder).
Best is a script called TrueDisplacement or so, which will displace according to a uv-mapped grayscale image-texture.
None of this will generate more vertices, so for smooth displacement you need “some” of them.

Modron: Displacement mapping (3D) different from bump-mapping (2D) 
tordat & DanielP: Thanks for your help! Even though it’s not “real” displacement mapping yet, interesting to see a nice vertex-displacement technique being implemented so far. I do this in Houdini a lot too.
Actually, there is a tex plugin that will do that with the clouds texture, and another that does the same with either the marble or wood texture. I’m not aware of any that will read a loaded tex though. (such as a height map in terragen, though you can import terragen meshes with the ter2blend script.)
i just found the page with the aforementioned plugins. This would appear to be similar to what you were asking about:

Modron, ther is a difference between displacement mapping like MG is talking about and bump mapping like you mention. Bump mapping is an “illusion”, for example:
Create a sphere.
Apply clouds texture with bumpmapping.
While the sphere now appears bumpy, look closely at the “edge” of he sphere and you will see the profile is still prefectly round, not bumpy. Bump mapping uses shading to create the appearance of the bumps, where displacement mapping actually deforms the mesh. With true displacement mapping the profile of the ball would show the bumps too.
Having never used a high end 3d app, I was confused about the two for quite a while myself, and hope Blender gets real displacement mapping someday (maybe for 3.0), wouldn’t it be nice?
Modron, where is this slider. I’ve found Nor button, but I can’t see any slider.
It’s on the bottom left of the materials window, a set of three sliders, one says ‘col’ one says ‘nor’ and one says ‘var’. Be sure you hit the ‘nor’ button on the FAR right. there are two. one is closer to the middle.
And toka,…look more closely at the plugins,…see the ones that look like mountains? that’s definately not bump mapping. That is 3D.
Bump mapping only gives higlights to the 2d texture on a mesh, displacement mapping actually displaces verts in a mesh according to a 2d hightmap.
And toka,…look more closely at the plugins,…see the ones that look like mountains? that’s definately not bump mapping. That is 3D.
Texture plug-ins can not manipulate a mesh, he probably used the hight map faetures of the plug-in to generate a (sort-of) displacement map button in (it’s the noise button i think) editbuttons.
Thank’s Modron 
Ah, thanks, dittohead, and, you’re welcome, Mkul. I love the noise button btw, I use it all the time.
