I wonder if it is possible to change the resolution of a smooth object after it has been generated? I want to convert a smooth object to facetted, but get very coarse results (a revolved circle, forming a quarter dougnut). I tried the 'additional triangulation' option, but don't get finer results.


tnx
wim

Wim,

Yes, you can change the resolutio of a smooth object after it has been generated.

Just query the attribute of the object (query attribute tool, or right click) and double click on display resolution on the list.

Here is a simple file with differents settings and a derivative facetted object. (to edges, none, none)

application/octet-stream...
1.fmz (360.1 k)


Hope it helps.

thanks JL, you are a real life-saver (or rather a time-saver). it worked fabulously (spent half an hour browsing through the manual pdf but could not find it).
I was unable to open your file, but I am still on 6.0, the update is on its way (I hope).

greetings from the sunny Belgium

Perhaps this pallette is of interest to you?

Thanks Peder,
that looks like a great tool! I must admit, having used FZ for architecture only for the last 10 years, and having used facetted models only for that, I feel like walking on thin ice now that I have other needs and start using smooth objects, nurbz and the like.
but it is fun, although a hard learning curve, which is horrible if time is restricted.
Here is the first rendering (no materials applied yet) of the corrected model, thanks to Jean-Luc for his prompt answer (I am so happy not having to rebuild the faucet, especially the rounding at the joins gave me grey hair!)

thanks again

Peder,

Thanks you very much for this link...
Pylon is definitvly a great guy.

Vim,
I'm happy to have saved you life!
Here is the V5.5 version of the file
application/octet-streamV55
V55.fmz (347.9 k)


Nice rendering by the way... RR atmospheric? RR Hdri? other rendering engine?

J-Luc

Ps
You watch the french television! Be carreful to your eyes

JL,

MW (just like you do)
thanks for the file, it opens now. (can't 6.1 output 6.0 compatible files? not that it matters, just curious) anyway, my 6.1 CD should arrive any day now.

Wim,

formZ version 6.1 can write any format between version 2.8 and version 6.1. I bet Jean-Luc wrote the earlier format so that others could look at the file, even if they do not yet have version 6...

Hi J-Luc,

Thanks for the complement!

Wim,
Your model and rendering look great. Smooth modeling in formZ is really powerful and fun, so I'd say keep going with it. The whole faucet could be made as smooth models. A few advantages:
1. Resolution independent renderings. Get facet-free renderings regardless of how close you are to the subject, or how high the rendering resolution.
2. Retain many parametric controls after the object is initially generated and edited. (Example: Boolean difference a parametric cylinder from one face of a cube. Then select the newly created curved face with the edit controls tool. Result: you can still edit the parametric controls of the underlying cylinder.)
3. As of v6, you can transform points, segments, and faces of smooth objects just like you can with facetted objects.
4. You can use smooth objects for CNC milling and other manufacturing processes.

Ben

Looks cool, (what exactly is that thing?)

Still stuck in facetland over here...

Ben,

you're right about most things. but here is a problem I ran into when modeling the part that connects the faucet to the watertower, so your point #3 is only partly true...
I create a truncated cone, then I move the larger circle (the "bottom" if you like) so that it is offset from the center. after I did that, I could not perform another transformation, like rotating that face. I tried rotating first, then moving, but same story.
did not find anything on that in the manual.
any ideas, Zweb?

Peder,

it is a giant faucet which will be mounted onto a real 80m high water tower. it is an ad for the tap water company.

here is another test

Wim,

formZ allows moving many different parts of smooth objects, but if the resulting object is not able to be calculated based on the move (or rotation...) then the change is not updated. (To tell more about why we would need to see your object...)

However, to do what you want should be quite easy -- just draw the two circles in their desired location and generate a Nurbz Tight Loft between the two using a Depth Degree = 1. Does this do what you want?

Zweb,
your suggestion is definitely better than how I solved it, I figured that rotating then moving can also be obtained with only rotating, but with an offset centerpoint. but this can only be achieved with trial and error, so your method is more straightforward.
thanks

Hi Wim,

I have noticed some irregularities with #3 as well. Whenever I find them, I try my best to report them so they can be corrected. I'm a big enthusiast for these new functions and want to see them bulletproofed.

Pylon,

A while back I reported an issue regarding #3 as well.

http://www.formz.com/forum2/messages/16/17438.html

I'm surprised it wasn't fixed in the last patch.

Craig,

Most of these issues need to be reported to Spatial Technologies. We then need to wait for their corrections and incorporate them before the fix will show up in a released version. So these can take a little longer than corrections that we can make ourselves. :-)
