Cushion pattern

Recommended Posts

Hello Odforce

Would anyone have an idea on how to approach this pattern (I would prefer to model it than displace render it). This is a watch bracelet.

I have made multiple disastrous attempts which are not worth posting here.

Many Thanks

I know the rest but kind like you sweet spot for the double sweep :)

Obviously you give that and there will always people will ask for some fancy pillow

I know, the double sweep put me on my butt.. the first one looks like it failed and then.. magic. I still haven't worked it out..

 

Now I need to make the tread to poke in and poke out of the leather.. I am thinking of using a sin wave function but likely beyond my capacities.. I'll give it a shot

Vincent to Vincent... Here's one way, hip attached

You could easily change the lacing design from this setup. Ok, there is more than 5 nodes here ^_^

Hey Vincent, you guys are awesome. That looks like another solved one. Finally showing the web community how to do stitches without Zbrush. I am not near my rig right now get back shortly.

Hy Vince, really nice. I learned a lot reading through the nodes.

So I tried to combine Konstantin's take and apply the threads.. taking a little shortcut.

The 2 problems that I have left are:

- I need to orient the loops in the direction of the lines to match the reference above

- I am having a hard time getting a nice smooth twist for the wires

 

If you can

Cheers

@N = set(0, 0, 0);
 
v@binormal;
i@group_group1 = 0;
 

if(@ptnum != 0 && @ptnum != @numpt-1)
{
    
    vector p0 = point(geoself(), "P", @ptnum-1);
    vector p1 = point(geoself(), "P", @ptnum+1);
 
  
    vector v0 = normalize(p0 - @P);
    vector v1 = normalize(p1 - @P);
 
  
    v@binormal = normalize(cross(@N, v1));
 
    
    if(dot(v@binormal, v0) < 0)
        i@group_outerPoint = 1;
}

Make two Groups/corresponding sides  and Shift, Play with Normal's. Have Fun

There is many way, but if your case, no curve banking or need to build parallele transform, just add 90degree roration on Y at your transform2, and that's it :)

PS: By the way, if you want more control on the deformation, you could just replace the last line of the def plane  wrangle by something like this

v@P.y += chramp("adjust",fit(dist,0,radius,0,1))*ch("mult");

Is this for the twist of the string itself?

I applied your function to the wrangle. Works real nice with 'round' curve. Gives me that master control.

 This is what I got right now combining all you guys techniques.. pretty neat

 

Yeah I would just improve the twist if possible, extrude the leather..bend it and roll..
