generative modeling for Rhino
I have a problem and hope for help.
I want to construct (Rhino & Grasshopper) an object, which consists of different sized balls, who shall merge with each other. Ensuing I want to “drill” holes to the surface, similar to the picture above.
Can anybody help me?
Perhaps it is totally simple, but I’m a terrible amateur, so please help me! :)
Thank you in advance!
Hallo alle zusammen!
Ich habe Problem und hoffe auf Hilfe.
Ich möchte (mit Rhino+Grasshopper) ein Objekt/Gebilde erstellen, dass aus verschieden großen hohlen Kugeln besteht, die miteinander verschmolzen sein sollen. Und dann hätte ich gern ein paar Öffnungen auf der Oberfläche, ähnlich wie das Bild oben. Kann mir jemand helfen?
Möglicherweise geht es auch ganz einfach, aber ich bin der totale Anfänger auf diesem Gebiet, also bitte helft mir! :)
Danke schon mal im Voraus!
Other Examples, also possible:
Just to get you started: the merged balls can be created with metaballs. After you have a mesh there are numerous ways to punch holes into it. You can search for "voronoi on surface" or "weaverbird".
Thank you for answering!
I know, I tried a lot with metaballs, aber at the end the balls had not really a surface to edit.
As I said - I'm a amateur, so maybe my way to construct a curcuit was not the best one.
So can you show me how to construct a simple curcuit? And I have no idea how to make these holes in it...
I'm not a pro in metaballs so I have to rely on the forum myself. Looks like there is no easy way to get a mesh from the metaball component.
As for the holes: once you have the mesh, you could punch holes for each mesh triangle with weaverbirds Frame component.
Thats what I tried. The first one I tried a view days ago, but at the end there is no surface, only curves. I cannot drill holes in curves. And at the second example I couldn't find a curcuit, so it doesn't help me...
Therefore I look for another way to construct my object...
Is there anyone else who can help me? I saw a lot of nice objects, but with almost no curcuits.
As I said, I have very few experience with rhino and grasshopper, so unfortunately I'm not able to create the curcuit after reading some texts... Often I don't know how to connect some compoments...
So If anyone has an idea how to realize this, PLEASE help me!!!
The links I posted both stated, that you would eventually need to bake points or lines to rhino and create a mesh there. Then reimport this mesh to a GH def. Which is probably why there are no defs for metaballs.
I'd reccommend you work through some of the tutorials before you start into complex stuff such as metaballs. I know it is tedious but since you're a beginner and
Often [...] don't know how to connect some compoments...
And on a side note, as one of my Professors once put it: "Grasshopper is for when you're sick of doing it all manually in Rhino". Which is to say: most things you will do in GH are possble to do in Rhino. If you have no clue about how to do it (at least in principle) in Rhino, forget about GH. This isn't meant do discourage you, but learn how to hold a hammer before you try to drive a screw with it.
I like the play on George Santayana's concept which gave rise to the paraphrase:
Those who cannot learn from history are doomed to repeat it.
When altered slightly becomes:
Those who cannot learn from (Explicit) History are doomed to repeat it repetition.
Of course this only works when you remember that Grasshopper used to be called Explicit History :)
Yes, your right. But i don't have enough time at the moment to deal with this programm. In this initial I hoped for help in this way.
If I have someday enough time to deal with the programm, I will not start with metaballs... :-)
Is there somethere an expert in metaballs...? At least a little bit?
By the way, It does not matter how I wanted to look like. If anyone has a good idea how to make it like the picture above, please help me. It is so difficult to work with this programm, if you have no idea of it...
