How to make organic forms?

Hi, I am a basic user of Rhino3D, now I got a task to draw a dripping form (gonna be small size as earrings) -see attached picture.
Any ideas how I can do that? I’ve tried to use T-Spline plug-in, but my computer became very slow so I couldn’t really do anything..

I hope someone can help solving my problem <:)

Tsplines is really the best way to go about it in my opinion.
When you have the Tsplines HUD open if you use the number keys 1, 2 & 3 you can make the form less smooth (just visually) so that you don’t tax your computer nearly as much. Using the Tab key when the Tsplines HUD is open will also allow you to go back and forth between box model & smooth model.
With Tsplines you want to use the least amount of faces as possible to get the shape you want.

Using Rhino to model this with surfaces would be a pretty daunting task. Perhaps someone else has a good suggestion on where to start if you want to use Rhino surfaces.

The easiest way is to use the pipe command… Draw the top curve and then the drops as curves. TSPipe and mess around with the radii and location of the joints.

Once you’re happy with that add a seam along the equator and delete half of the model and then mirror along the equator so that what you do to the top happens to the bottom too.

Select points and use the move and the scale command - select them in groups of four (the circles that made up the pipe) and scale them as below. I’ve started on the left but not finished it. Mess around with it in box mode - if it doesn’t look right in box mode then it won’t be right in smooth mode… Try and keep the flow of the seams.

Thank you for your answers, guys! I hope I can manage to draw it now :slight_smile:

Wow… I was looking for a quick and simple solution to drips and I came across this, which I responded to back in 2016! :sweat_smile:

I’m no longer 2DCube though.

The SubD bits in Rhino 7 are great but there is still a lot of missing functionality from T-Splines.

The multi pipe command in T-Splines was exceptional, I used it for a coral project, which I wouldn’t be able to do today, with Rhino.

Do you know if there is going to be any added functionality?

Cheers,

Andy

The one below with the red curves was my T-Splines response back in 2016 and the poor line of ‘drips’ above it is the 2025 Rhino equivalent

i only have rhino 7 here now, but it seems Rhinos Multipipe will bring you close to it, then just gumball extrude the tips for more segments, scale and reposition the edges.

though i also would love some improvement here, setting the vertices direction or adding multiple radii here would be great indeed, i believe the radii part is possible in grasshopper, at least it was when it was introduced.

Ah yeah, that’s a work around.

The control cage was accessible at all stages, where you could tweak, change radii, move them along a guide curve, and add/remove sections and scale each point and/or rotate is at any point.

It was so helpful!

This was my first attempt back in 2014/15 after purchasing T-Splines…

They were eventually 3D printed, moulded and cast (I think the idea was that there were going to be platinum plated? I can’t show the full thing even now, sadly 11 years later)
