Water modelling

#1

Hi again guys, long time =)

I just posted a tread about this in the general modelling section, so sorry for dubbleposting. However, I am a all-rhino modeller, so maybe you have som better answers for me…?

So the thing is… Im hired for making hard-body modells > pointclouds for crystal ingavings. This is the easy part… Problem is that Im considered the modelling guy, by a boss who dont realy see the diffrence between hard-body and water effects:p He want me to make a hi-detailed pointcloud formed as a breaking wave, fram som reference pic’s of his…

I neverd work with water before, hardly tuched poly’s for years… anyone have any ideas where to start? Does Rhino have any usefull plugins? Or do I need to go ahead and earn a new program dubbletime? hehe… so much for hollydays…

modelling rough water in motion would be a real PITA in Rhino :slight_smile: - but there r nice fluid and particle systems in e.g. Maya - although doing a breaking wave might need some effort there too.
The only thing within Rhino which might help is the Blobby Tools for Rhino - a script for Rhino 3, which uses Rhinoman and AIR-Rendere (preferably but not necessarily) to create fluid like bubbles and blobs out of clusters of primitives - haven’t tried myself, but it looks quite nice…

can u show some example of those engravings? what size do they measure?

Hi again…

Well actually I gave up on this one… Water over my head, convinced my boss to pay somebody else to do it, someone with organic-modelling skills I guess… Hehe, better keep
to what your good at right?

I do have new projects on my hands though, seems Im stuck with a lot of smal stupid tasks, after I started working with theese crystals…

anyways, thanks for your help, but sometimes it’s just not worth it :shrug:

Hey, do you know how to create a surface with Z-cordinates from a bitmap? Easy task in Max, but I naver done it in Rhino before. Im planing to make a map of Norway, stylizing some mountans++ :slight_smile:

I like such crystal very much - unfortunately they are usually not so cheap :frowning:

Concerning your relief - that’s easy in Rhino as well - the command is called “Heightfield from image” [ _heightfield ]; it’s in the surface menu - should do the trick, although something complex as the norwegian landscape most likely will result in a massive file… but I’d love to see the results !!!

#5

ooh, hehe… blush, I’v been looking trough plugins for about an hour… Simply overlooked it, in the command list:D Thanks mate!

As for the crystals, they’re a lot of work to make some times, defined by pointcloudes, and a mess to get right:) Beatutifull up close though, if my comp buy their own laser, Ill send you some =)

#6

I’ll take you up on that g
Just out of curiosity - what resultion do you need in order to make such a nice hollow model as the ship you showed above ? How are they created anyway - i mean how do u get the hole within the solid body?
or is it “just” 2d-engraving ?

#7

Hehe, they are full 3d, and are made by several lasers from diffrent directions. Only where the lasers cross, its produced enough heat to melt the glass, and make a tiny bobble (150-250 μm. Not sure what ress. you “need”, depends on what effect you are after, but the laser can ingrave points side-by-side… =)

#8

2C if i got it right: so the inside isn’t actually hollow but you “only” create surfaces (with bubble arrays :slight_smile: within the crystal box ?

#9

Yupp, thats right, I just feed the machine pointcloads, and out they come=) Thats y its tricky, getting from nurbs to stl’s to pointcloads, and get cloads with the right desity all the way…
