Hi there, I'm trying to make a silver ring in Rhino and it needs to have hammered finish right on the model (not texture) so we can print it in wax and cast it.
I have no idea, however, where to even begin to make the ring surface hammered. I'd really appreciate any help.
P.S. attaching img for reference.
This is as far as I've gotten it for the moment - not too difficult but then it's a long way off from your picture ring. The model is in my public projects if you want to have a look.
I started off with a hammered texture picture I got from phoenixcnccreations.com and drew closed polygons over it.
I made a linear array and filled in the missing bits to make a tessellation piece that could be repeated and deleted the array bits
I copied these scaled them inwards in 2D and rebuilt the copies as degree 3 curves which I then moved down along the Y-axis (see picture)
Then I used a patch surfaces selecting both the polygons and their degree 3 counterparts. In the patch surface dialog box I played with the stiffness to get the desired shape.
I then used a planar surface that I moved slightly into the patch surfaces and did a trimming operation to make a single polysurface which I then tiled to get enough to flow along surface.
I have some ideas as to how get it better but I think that zbrush might be a better call for arriving at the type of finish shown in the picture.
The best way is to extract the surface you want to look hammered the add more points to that surface then click on each point and pull them up or down as you desire. The more points you have on that surface the better it will look.
This is how you do it , type rebuild in command bar, click on rebuild, click on the surface and enter, a box will open, put higher number in point count (U and V) then click on OK, then turn on the control points on and pull the points up or down , make sure the o snap is off and also you have to work in all four views. good luck
_move uvn command is very handy for this since most of the point editing is in the direction normal to the starting surface. So you can get the bulk of the tedious work done qdone quickly
Try T-splines, demo have 25 saves.
Good thought, I'll have a go and post results... Expecting the complication to be petering out hard edges in the middle of the scallops to get the balance of hard and soft edges right (TSweight maybe?) and n-sided faces.
Let me know if you make any progress
You could make the same look by using different size spheres and boolean differance on the surface.
Use GH in Rhino to get surface then flow on the right .
Why not make real Hammered finish if you don't make a lot ?
