What program? Not all can do that kind of work. I'm just curious. Thanks


zbrush, ...also can be done in maya, abit harder but doable..
cheers!

A while back I needed to make some cobblestone surface, and I used Solidworks to make a grid of stones, then used MeshLab to transform the stones into something more organic.

Here is the same technique applied to a set of bricks.  You can use any program to create the basic brick set, export it as an STL or OBJ, then use MeshLab to do the transformations to the mesh

I'm including the STLs, but you should probably do your own.

Sorry, I couldn't upload the last file, it's too big for the server (7.49MB).

Its how you add 'texture' to a 'texture' by fudging the objects 'normals' wink

http://en.wikipedia.org/wiki/Bump_mapping

Sketchup doesn't really do bump mapping... it requires 3rd-party rendering tools such as VRay (there is a freebie version or trial from memory... )  http://www.vray.com/vray_for_sketchup/m … maps.shtml

There are a few RGP objects out there with surfaces like that which you need.
You could just pull one face from one of those and work from there.

Most commercial modeling programs have "textures" that do not offer actually real effects. It will give you the look of stone, but not actually have those qualities in the STL file.

Sounds like you're stuck making it yourself. Seems like you need to make the basic block, and then use some form of "geometric pattern" tools to repeat the pattern. It will look slightly stiff, since real stonework isn't perfectly uniform.


But if you really want the true modeled stone look, as it sounds you do, then it will require use of blender most likely. Sketchup is a geometric modeling program and not as well suited for the sculpting sort of operations that blender is better at.  autodesk meshmixer would also be decent at this, though I've never gotten the hang of it.

Howwever, a cheaper and less problematic approach is to print it in any preferred filament, probably best at a higher resolution, then pick up some Rustoleum. They make a paint in a spray can that resembles stone.

Can someone point me in the right direction please?
Thanks
