shape a cloud

[danipa]

Hello everyone are a new user of this forum.. .
I wanted to have some advice on how to create and shape a cloud.. .
starting from solids, surfaces,... I don't know!
I hope in your contact

Welcome to the forum,
To help you with some other information, for example, should you tell us what kind of cloud you want to model, those of comics? or simil-realistic? cirri, nembi, or what else?
good stay soon.

Sorry, I was a little too general. ...
The cloud must be symil-realistic, it doesn't cause too thin strands, I'm getting closer to the idea I have in my head.
must have a very soft shape and not like those of the comics too pumped and full, you have to approach the real... .
I attach an image so you realize the shape I have to achieve

 

[Ezio Olivato]

given the sample image and thanks to clarification. still one thing to consider and that is if the result of the modeling will become part of a static image or video, it simply changes in the sense that if a static image remains, you can also rely on modeling through solids; if you have to enter a video you must use the mesh: because the latter weigh less in terms of kb.

I just need to shape it and then make it for a project board. . .
so more static images of the cloud and no video...
Thanks again

Please, you're welcome!

You always start from a nurbs, then when you like it, you make a mesh so that it weighs less, but only then, because you lose so much information and you can no longer change it.

I'll tell you how I'd do it.
I would design a sphere, insert some isoparametrics here and to inflate the control vertices. Then I would select groups of randomly, more or less distributed, and I would scale them to the center of the ball. the same groups can also be moved up or down to make a wave effect.

made this, uses a material that has a shaded transparency outwards, so as to achieve an evanescent effect.

Okay, it's badly shaped, but I did it fast, just to figure out what I meant.

Carina!

I'm sorry if I answer now, but I couldn't connect yesterday. ..problems with wind...
I read your method now. It seems to have a great result. . .
but explain to me what the sphere is and how are the isoparametrics added?
a last question you used seems to give a good result....

I didn't use rhino, but the process is the same. for specific commands you have to ask someone who knows rhino, however, in the first line it leaves the increase of the complexity of the surface, starts with displaying the control vertices and move them a little by hand, see what comes out.

for the material, I made one myself, a white with a mapping of the transparency of circular type, with matte in the center and transparent at the end

Now I'm starting to shape my cloud. . .I hope that with your advice reached a good result. . .
cmq qlc I reach her after what you told me, result that I would never reach alone.. .
Thanks
