Loft questions
-
Chris,
It might be worth also looking at how 3ds Max handles lofting. Although it only uses 2D splines, there are some parameter adjustments in the modifier panel that would be interesting to explore and possibly adapt into sketchup functionality, particularly the "fit" option. These two loft tutorials show pretty well how it works and they give a glimpse into the loft modifier rollout panel. Let me know if you want me to take some screen shots of all the Max lofting parameters.

Thanks for the links Adam. I've tried to use the loft tool in 3dsmax and I've done basic lofting with it. But that what you showed is very advanced. Probably out of the scope of what I think I'll ever be able to implement. But perhaps simplified versions of that could sneak into scripts. But I suppose I would have to understand how that stuff works in order to implement it.....

What is the difference between your future Loft Plug and the Sandbox "From Scratch"?
-
From scratch essentially just draws straight lines between the curves (contours).
Curve stitcher is also similar to this loft script.
My loft will (theoretically) draw bezier curves between the curves. But with just 2 curves, there is realy no way to set up a bezier curve. But with 3 or more it should/will work great.
And on top of that, my script will adjust for curves with varying segment counts, hopefully work with closed and open curves, and it lets you control how many segments are created between each segment.
Here's a video. I was planning on releaseing something tonight, but I've gotta go to bed instead. I'll try to release this tomorrow. (it might take a long time to load, so just keep waiting for a bit....sorry)
This video is not for the faint of heart - 22mb and 3+ minutes of no sound. It sort of shows how "from contours", curve stitcher, and loft compare. But again, my loft tool has a few more key features to add.

Sweet! The curtain shape looks really nice.
No sleep for you!! Get some caffeine and get back to work! ...pleeeeease...

Cool pedagogic demo!
So your future plug is also a sort of subdivision tool -
Really cool stuff Chris! Would you ever see the script being able to be used in the same fashion as From Contours for creating landscape terrain? It would be great to have a tool that would act as From Contours does, but result in a tessellated mesh that could then be adjusted with the Smoove Tool.
With the ability to tessellate lofted meshes, the next thought would be a tool that could sculpt the mesh. Acting similar to the Smoove tool in it's soft selection, but allowing for dragging the tool to raise each face along it's normal. The pressure of the sculpt tool could be adjusted based on the height each normal is moved. Do you think this would ever be possible?
-
The "Smoove Brush" tool would be a neat feature. I use Zbrush for alot of my soft modeling needs, but sketchup is starting to horn in on some of the easier stuff.

Thats a cool demo, I've seen their sculpting tools before, they are incredible!
I think that the demo shown there, that level of sculpting, would be possible with SU. I could be wrong though. It might have to be done with all edges turned off. And it would never be able to do as much detail as zbrush. Just typing the phrase "billions of polys" on this computer just crashed my SketchUp I had running in the background.

Pilou, in what program are you making those loft images?

Moment of Inspiration
(Moi)
(just image colorisation is made in 2D prog for fun & varietyI don't believe that SU can actually makes the same than Zbrush!
There are 8 000 000 polys in normal way at level 7 of subdivision !
And it just one object! So when you will make many objects in the same time
SU will freeze before
