[Plugin][$] Curviloft 2.0a - 31 Mar 24 (Loft & Skinning)

Joel,
Sections are computed idependently for the vertex matching, so if contours are very different, you may end up with the situation you describe.
So far, the only possibility is to use the Global F-spline options. It draws a mesh between the first and last contours trying to be as close as posible to the intermediate contours (but not matching their vertex).
This method is the first one of the group of two icons at the right of the Junction methods section in the palette.Thanks to tell me if this option is useful (I included it just in case....)

Hi Fredo
Thanks for your reply. yes i did try the global F-spline options and these are the only options which work. They are definitely very useful; thanks for including them!
What I don't understand however is that the 3 profile curves shown in my example are very similar: they are actually three copies of the same uniform b-spline with slight adjustments to each. They have exactly same number of segments and the segments are all aligned approximately above each other, So I'm not sure why curviloft creates extra intermediate junction curves in some places?
Is it possible for Curviloft to gauge when all the profile curves have the same number of segments and do direct vertex matching without the extra junction curves? The reason being that the most logical way/neatest way of doing a loft is to use Bezierspline to give each of the profile curves the same number of segments before lofting.
Also, any idea about the second issue? the one where the quads are all merged into a single long face? Sorry if I'm a bit long winded, but I'm just very excited about the integration between Curviloft and Quad face tools...
Cheers,
Joel

Could you post the model so that I have a closer look
Thanks

JoelI too have noticed (and remarked about a long time ago) CL's penchant for adding multiple vertexes where none should be logical.
CL does a fantastic job of lofting, but often adds a lot of unnecessary lines that I spend a lot of time simplifying by simply deleting the redundant lines and triangulating the quad face. It is rarely a logical midpoint on a straight-line split, they seem to me to be almost random in generation, both position and number.
I haven't tried the new version yet, and I won't have time for a while, as I only get less than an hour on the PC a day due to a temp. 12 hour a day job.

Hi Fredo
I've attached a model showing the problems I described. I've showed the exact steps i took and colour coded/labelled the problematic areas.
Thanks so much for looking into this!
Cheers,
Joel

Have you same result when you scale the B Splines *100 ?

Joel,
I had a look and there is definitely a problem in the vertex matching. Actually, even if the number of vertices are the same, thereare some which are very close and unequally spaced. This create issues with the current matching algorithm which still needs to be improved in case there is no 'sharp' edges to be used as a reference start point.
In addition, the problem of vertex matching makes the Global F-Spline method not really work. But I knew I had problem on this one.
I am afraid that this cannot be fixed instantly. What I suggest is that you play with the vertex matchning by dragging the junction curves and eliminating the auto-pairs.

Thanks for looking into it anyway Fredo. I guess this issue of vertex matching becomes very important now that there is a lot of buzz going on around thomthom's quad face tools which require a regular set-out of quad faces in order to properly utilise features such as loop and ring select etc.
My dream is that one day this kind of quad-based system will lead to a free-form paneliser tool for SU. I posted a topic on it here:
http://forums.sketchucation.com/viewtopic.php?f=323&t=39992
It has huge architectural implications for architects like me who use SU heavily as a design tool. Not many people seem to be interested in it though...which is rather strange.
Cheers,
Joel

thanks freddo ...!!unbeleivable..

Hello everyone! I'm newbie to this community so I just wanted to thank you for sharing this wonderful information in this thread, it really helped me a lot!
-
this is great
-
I'm loving this tool Fredo! So quick to generate a nice clean mesh - and with the latest Quad option - working with it afterwards is such a joy!

Glad to see that this is useful for real-world modelling.
I have installed the Quadtools and start playing with it, trying to catch the essence of the tutorial videos. So far, I am still struggling to understand how to do a simple application of an image texture on a shape, but I will try again.Fredo
-
I got on my todo list to make some more tutorials.
I also need to update QuadFace Tools to give proper feedback to the user when the shape can't be mapped to a 2D grid. Please post back with the things you find troublesome - with sample models would be great. -
Bonjour
est ce que Curviloft marche sous Sketchup8 (mac)?
MerciHello,
does Curviloft work under Sketchup8 for mac?Thank you

Hey everyone, I downloaded this plugin and sketchup tells me that there have been errors loading the Curviloft plugins, though they are in the same folder as the LibFredo6 plugin as well as Tools On Surface plugin (which works great, by the way). Is it a bug with this version? I tried telling the Ruby Console to load the plugins, and it accepted some of them but about half of them have problems and as a result Sketchup won't show me any of the tools for Curviloft.
Thanks!

What are the errors you get ?

I just downloaded and tried to use the Curviloft plugin and am getting this error with sketchup 8 on a Mac.

Looks like an installation error to me. Could you post a screen grab of your Plugins directory?
