Full Version: [script] Morph between two curves

Show messages:  1-5  6-25  26-29

Does it give the same result that you'd get by lofting a surface between the curves and then using the Iso curve tool on that surface?

Hi Burr,

> It does a Morph between 2 curves.....

Still not getting it, I'll install it when I get home so I can get the jist of it.

Cheers

Hi Max.

Excellent script. I could really use it for a project i was working on a couple of months ago.


Thanks

Thanks Max!

Similar to a Curve Blend in Illustrator.

I wonder if it could possibly use History like Loft?

Ok with your script + Lineweb you can make some crazzy thing! :)

""""""""""Does it give the same result that you'd get by lofting a surface between the curves """""""""""

It's pretty close to the same as just lofting the 2 curves, with some slight differences. I guess you'de have to look at the script code to see how he's morphing.

It does give some interesting possibilities to being able to control the output. Like if you needed to tweak the loft in "Very specific areas", you could then re-run the loft on the morph curves with some changes.

I think it's a compliment to the isocurve, but not a replacement. First, it is automated with nice even space between the 2. The iso curve is more for working on an existing surface and staying with it. This is more for generating a surface. I like to think of it as Generating a surface from isocurve, as opposed to an isocurve from a surface. :o

Maybe the isocurve could be beefed up to do an "even spacing" over the entire surface, with a single pick!

Okay I get it :P

It's an automated/lazy person Loft then take sections of the Loft at certain increments :)

Thanks

""""It's an automated/lazy person Loft """"""

Well, in a sense. It allows you to work backwards in that sense. The other thing it can allow is to create a surface with a very specific point structure.... Like needed for "flow".....

The other thing is if you look at it with regard to 2d drawing/artists, you can do some cool stuff/shapes!

Great for 2D/3D hatching!

Hi danperk, also for doing that kind of hatching trimming, you can use curve booleans as a shortcut instead of using Edit > Trim which it looks like you're doing there.

Start with all the hatch lines selected:



Run Construct > Boolean > Intersection, then select the closed curve region boundaries. That will then generate a result like this:




The lines will be cut by the boundary and only the parts of the line that are on the active area of the 2D region will be kept.

If you want the other way, use difference instead, that will slice away the stuff inside the active 2D region like this:



You can use Trim too, the booleans just basically automate the picking of which pieces to discard or keep.

Good tip, picking the discards was adding unnecessary work!

Thanks Michael!

---

Very cool Max! Thanks for a great script!

Wow this script looks awfully useful!
Many thanks for providing this!

---

Great script! However, sometimes a morph between two closed curves yields several intermediate morphed curves that are open instead. Which makes it difficult to use for further lofting, as it is very hard to find the open spot (I know there's a script for that too). Maybe could be improved? Thanks!

---

I used lines (opened curves) to build morphed curves. But now the script uses different method in situation when both curves are closed. It uses circles instead. :)
Thank you for advice.

Cool plugin but something curious! :)

So it's you or Michael who have made an inversion! :)
I presume it's you for any secret reason! :)

(not a big deal as the Flip Command exists in Native in Moi : just select a curve(s) and Press Tab then type Flip! :)

I first use CMorph between the 2 yellow curves then LineWeb! Careful! Order of select curves is important for LineWeb!

---

It works, thanks Max! Only thing left now is the flipped curve direction as Pilou mentions.

---

Ops. Just forgot to check this :)
Found. Fixed. Uploaded.

---

This is really cool Max, thanks for posting it and updating it!

Cool! ;)
