Hi PaQ, your ghost mechanical horse there looks like a good example of a combination of different styled elements.

Like I could imagine doing all the legs in MoI and the skull in a subd modeler.


I can understand that it would be cool to have just one environment that had every style of tool available in it so you wouldn't have to do any switching at all. Maybe look for that in MoI v4 or something... :)

- Michael

For exemple here are some models I made, they are not completely fit what I want to show, but it's just to give an idea ... and I have nothing better here :




Here's an helmet I did ... It's all sub-d. 90% of the model would be so easy to build in Moi (or any other nurbs software I suppose) ... but there is a detail (not very clear
in the image sorry), there is a face behind all this tubes, not very detailled, but still enough that I have no idea about how to build it in Moi.



Same here, all the body is mechanic and it was really time consuming in sub-d ... the skull was of course more funny, but really I would prefer to have
less details in the skull and be able to get a nice blending with the mechanic part for this model (I didn't have the energy to complete it).

An other exemple (not mine haha), I-robot ... you see what I mean about mixing organic and mechanic ?

But as you describe, it seems to be quite hard to blend patches even with all the tools available, and it requires a lot of work that probably I don't really evaluate.

> Maybe look for that in MoI v4 or something... :)

Believe me, I will wait :o)

Hi PaQ,

Yup, definitely looks like all the main helmet pieces would work well in MoI.

But the solution is really straightforward - don't build that one particular piece inside of MoI.

Build the pieces that fit well in MoI inside of MoI and build the pieces that fit better in a subd modeler in a subd modeler...

There is no law against using more than one modeler to finish a project! :)

- Michael

It's okay Michael, I think we're all just marveling at how Jinn was able to model so wonderfully using NURBS.

Even though I've always considered you the Miracle Programmer because you program so quickly and with few if any bugs in your programs, I don't think we're expecting you to make make MOI into a crazy do everything modeler.

I was just voicing that it would be nice for MOI to have something that really separates it from Rhino but I guess being that you also created Rhino, trying to seperate the two may be impossible since they're both your work! :)

Wow!! Just logged on.
I started this thread 5 mins before I went to bed, logged on and it's full on in here.
Thanks guys, you've given me what I needed to know, great discussion.

Don't worry I come from an 'industrial' background in design and when I saw Jin's models I got excited. Now after my sleep, I've come back down to earth and realized that for me to achieve something like this I would need time, and a lot of it, I would have to leave the wife and sell the kids.

>>Even though I've always considered you the Miracle Programmer because you program so quickly and with few if any bugs in your programs, I don't think we're expecting you to make make MOI into a crazy do everything modeler.

I agree with WillBellJr I love the way MoI is now and any improvements will be icing on an already great product.

Hi there,
My last model I created was first done here all in patch modeling and yes it is a lot of work to re-combine the objects when bringing it into another program, but it really keeps a very smooth looking curvature as detail which I notice lacks in a lot of other Sub-D programs. I think my way of modeling has changed for the better at this point with Moi as the first building blocks. I would request a few thing if possible in the next upgrade as a time saver if possible can you make the exporter give an option to either separate each of the patches or be able to say combine each patch this way you don't have to cut a 100 objects into 1 layer such as in Lightwave or Modo. Last exporter thing would be nice would be to make the exporter also only export 4 point polys, I am sure this is a much harder thing to program but it would save a lot of time when trying to recombine the objects back together. Thanks for such a wonderful program though, the Boolean operation is out of this world in how it works! :)

I would like to add some more options to the exporter, but there is also a way you should be able to get this type of separation more quickly right now.

Start by exporting to the .obj format (instead of .lwo for this particular task), and make sure you have "Weld vertices along edges" turned off (expand the dialog by the little arrow to see this option).

Then after you export the .obj file, run the SeparateOBJ utility on it, which you can find here.

That will edit the OBJ file to mark each smoothing group section to be a different object, if you export with welding turned off each surface should form its own smoothing group so that will have the effect of breaking each surface into its own individual object and end up on its own layer inside of Modo.

If I understand what you want correctly, that should get the job done with just a couple of actions.


For combining instead of separating, you can use the MergeOBJ editor instead, which will combine everything in one obj file into just one single object.

Yes, I have definitely heard from a lot of people who would like to have this. Unfortunately it is a quite difficult thing to program, it is going to be a while before I can attempt it.

Thank you for the feedback Michael, I really like the timely answers. I will try the suggestions you gave and it should make my cleanup much easier thanks again.

Hi Will,

> It's okay Michael, I think we're all just marveling at how

It's definitely very impressive!

But you have to be careful of a pretty big trap - just seeing someone's impressive result may prove that it is technically possible to achieve something, but it doesn't prove that it is practical to achieve it.

By which I mean if it takes you 3 years of training your skills and then a week of full time work for each model, that is just not going to be very practical for many other people even though it will get great results.


> I don't think we're expecting you to make make MOI into a

:) But that is a pretty natural thing to want. I just have to kind of try and reign in expectations a bit because it's just not practical for that to happen all of a sudden, it will take a fair amount of time to get stuff like new toolsets for different modeling styles implemented.

Well, not only that but they are both NURBS modelers so certainly that will make for some similarities.

But MoI's interface is different than Rhino's by quite a bit. Things like selection, the display, how you activate tools and set options, all that stuff is different. That's not like a small amount of stuff, those are things that come into play for most every thing that you do...

I guess all that interface stuff seems like a big difference to me.

- Michael

And what about this t-spline techno ?
http://www.tsplines.com/rhino/video.php

Is it as promising as it looks ? 3*times the price of MoI Oo (+ a rhino licence) ... The obj cage conversion to nurbs looks sweet
to quickly create advanced organic shape ... just wondering how far you can go after that (booleans, fillet, holes, etc ...)

Hi Michael,

>>I guess all that interface stuff seems like a big difference to me.

Be sure it is a big difference, I've been using 3d cad for the past 10 years, I've used at least 4 and tried another half a dozen and the learning curve is always where to find the commands and once found what are they capable of.
Finding MoI was god sent. Seriously, the first time I launched MoI it took a matter of minutes to find where everything was and start modeling without looking at a single document and I have never achieved that with any other 3d software.

I watched a tutorial on modeling a car on NPower's 'Power NURBS' and as soon as the dude RMB a menu poppet up that looked like a frigging phonebook listing it scared me :o

It matters to me too, keep going the direction you're going.

Cheers
Danny

Thanks Danny!

Hi PaQ,

> And what about this t-spline techno ?

It is definitely very promising, it is the kind of SubD/NURBS combination type approach which I think will start to be seen more often in the next 5 years or so.

I don't think that Rhino is really the best environment for creating brand new subd models, it just is not focused on that kind of toolset either. Probably something like Silo or Modo is more likely to be where you would create the models originally.

But Tsplines lets you do some very interesting conversions from SubD to NURBS. Once you have all NURBS surfaces, you can do regular NURBS operations like booleans, fillets, etc... and you could bring those NURBS models into MoI as well.

- Michael

With all this "options" stuff around!!??

Really, if you do all you can basically in MoI, then take the say .obj file version, to finness, into the, say, Carrara6Pro Vertex Room "Displacement Painting" option----or, maybe even better, doing similarly in the brilliant 3D Coat app---does one really need more?

>I guess all that interface stuff seems like a big difference to me.

It is a huge difference to me too. The first time I tried your 'on the fly' construction lines I was hooked ;-)

I've done some interface design in my time and I agree with Danny that this is what makes an application 'work' for the user. Most developers don't understand this and underestimate both the importance of it and the time it needs to design and develop. What I find great is the fact that the first thing you're working on for V2 is a new interaction for scale, rotate, etc. Brilliant!

Please keep up the good work.


> I don't think we're expecting you to make make MOI into a

I do :-)

But not at version 2. Maybe by version 5 or 10 though. I'm prepared to wait.

"But MoI's interface is different than Rhino's by quite a bit. Things like selection, the display, how you activate tools and set options, all that stuff is different. That's not like a small amount of stuff, those are things that come into play for most every thing that you do...

Yes, absolutely! Owning Rhino v2 myself, I think I see mostly their similar command sets.

MOI's GUI is so transparent that I guess I sorta take it for granted but yes, the work you've put into the GUI is superb!

Even though I feel it's MOI's exporter that brings the most value for me, I have to say that it is most likely MOI's GUI that has me doing way more that I've ever accomplished in Rhino even though they do have a similar command set!

Actually I do as well! :-) (But I didn't want to tell Michael that just yet! :-P )

-Will

PS - I'd love to see what Jin would have to say about MOI since he's such a great NURBS modeler! Perhaps a CGTalk PM to him with a link here is in order... ;-)

Wow !! top mod model export as obj, then convert into t-spline and finally exported in MoI.
Having some trouble with booleans>merge to slice the model ... however it was easy to trim il by hand and doing some cool fillet :)

Incredible modeling perspective for me, but a little bit to much expensive :'(

And here's a model coming with modo :)
So cool :)

Having a patch modeling toolset is not a "bad" idea. But honestly if you are hoping to make something which handles organic modeling better than subd, i don't think you will achieve it just by using patches. It needs to be something more sophisticated than that if you are to overcome the limitations of working in Nurbs. TSplines is a huge improvement for organic Nurbs, and the poly-Nurbs conversion is awesome. I've used it on a few projects that we are now in process of making the injection moulds. But admittedly there is no modeling toolset (coming in version 2!) which compares to the ease and speed of using subd. However TS for Rhino does have a very nice tool (called tsSkin) that allows the input of a minimal set of curves and can output a smoothed solid model from it. you can define very complex forms with very few Nurbs curves. It's a fresh approach to Nurbs modeling. And i think new concepts like this are needed to make Nurbs a viable organic modeling solution...
