[Plugin] SketchyFFD (Classic)
-
Wow must say "an amazing tool"
One idea:
Mayby somekind of autohide could be added ?If I rightclick the object (the deformed one)I could select to autohide or show the FFD object. Then, if hidded, the FFD object will become visible when I select or doubbleclick the deformed object.
Just an idea
Thanks

Fantastic tool! Your generosity is greatly appreciated.

Bugs and limitations:
-BUG. If you start a FFD and the control points don't match the object you need to explode and regroup the object. Then try the FFD again.
-Only one FFD at a time. The script uses a few globals for speed.
-Only works on geometry in a group and only one layer deep.
-Sometimes hidden edges don't move right. Dont know why. Might be a bug in Sketchup.If you try this script much, it's tempting to 'do it again' in the same file... but SU will become very unstable... especially if you hit the undo with 2 FFDs in the file.
Best to heed Chris's warnings.
Great job with this script, Chris.
I would imagine building furniture in SU will go a lot easier now with this script to quickly tweak the angle on some chair legs, etc. -
As a convenience it would be nice if you could select one point and then be able to select all of other points that share the same x, y, or z plane.
First thing comes to mind is press "B" for the Blue plane, "R" for the Red plane, or "G" for the Green plane. Also, Ctrl-click another point to add another plane of points or Shift-click to Add or Subtract a plane of points.

Thanks Chris
This is brilliant, works fast on my machine and updates automatically, I don't need to click "update". Is that something you have added?

The only little remark I have with current plugin (besides saying it is awesome ), is that after some manipulation, it starts to become difficult to see which points to move.
It would be great if the control points would stick more to the geometry...I am not sure if my explanation is clearIs there some benefit in perhaps colouring the points on the ffd cube? I have no idea if it is possible to do this, but for instance, top points blue, north and south points green, east and west points red, bottom face black. Then, when you start manipulating stuff, it would be easier to see which point corresponds to what. Obviously the more complicated the deformation, the less useful this would become.
-
Interesting how the points are created with the attached.
The group was rotated, then the axis.
Apply an 2x2 FFD . The points kind of follow the user defined axis.
-
now, if you could get the smoove tool to work with this, i'd be really impressed
of coarse you'd have to find a way to unlock the smoove only working in the blue axis, there's the trick
-
The Smoove tool does work normal to selected geometry. Begin to Smoove something then press Shift. It's in Help http://download.sketchup.com/sketchuphelp/gsu6_win/Content/P-Terrain_Modeling/TerrainTool-Smoover.htm#kanchor392. Select some bits and use Scale. Lots of deformation possibilities with that.
-
gata, thx just saw that post before you posted here. been looking for this method for a long time
BTW, i see no mention of the shift key in the help documentation.Oh wait it is there in greyed out text, had to read it four times plus the numerous times i've looked before.
i'll return a hint to you; use the erase tool on a sandbox or similiar surface, then without releasing the LMB use a shortcut key to change to smoove tool. viola, you have a soft selection for smooving
Now if SK was only useable with more than a couple hundred surfaces i'd throw my other modelling software's away.

at the risk of getting off-topic here, I will just say that I will now have to post (for your view pleasure, xrok,
the animation I will finish before noon tomorrow using only SU. -
i look forward to it.
-
@Xrok... looky here.

Chris thank you for sharing this script! It doesn't seem to work for me though. It creates a group consisting of just one construction point no matter what I'm trying to manipulate (a cube or a donut), and no matter what option i choose 2x2 or higher. I'm on winXP SketchUp 5.
What am I doing wrong? (using script version from 12 feb, 2008)
TIA -
Ok. Ill have a new version soon and Ill post it there.
Chris.

Chris,
Would you start a thread in the Script Depository which contains just the downloads? That way, everyone can find it easily, and you can edit the page when you have an update.
Thanks.

TIAHmm. I dont know. Did you group the object? Open the ruby console and try it again to see if it prints any errors. Or post a model that fails and I'll take a look.

Has anyone actually used this script for anything useful yet?
The reason I ask is I have tried using it for few things and the results have been disappointing. Its ok for distorting shapes comically and making simple terrains. But I tried to make a simple boat hull, something I figured it would be good for, and it was just tedious.
Part of the problem is with more complex deformations (beyond (2x2)) its too difficult to foresee how moving the control points is going to deform the model. It certainly isn't predictable and it makes it difficult to match any but the simplest shape or design.
AND I am thinking that for the simpler (2x2 and 3x3) cases a more specific deformation script would be better. Something that could be done with real-time preview. Simpler deforms include shear, taper, bend, twist, squeeze, and inflate.

I made that pear, but thats about it so far, i imagine its going to be most useful for more organic shapes where precision isnt entirely necessary.
-
Chris, I used it on these guys and I they have been downloaded a good many times; so thank you.

yes sir,
I am experimenting, trying to deform a wine glass....
The knot itself and the feet and bowl of a straight wine glass are not 'FF' but imports I stitched together.
The deformations ('bending' like operations) to get the glass posed, and also the liquid, are done using FF ( = I rotate some points)
My conclusion is that the current FF is a rough but decent start for organic shaping.Chris, I think you can indeed only discover what actually needs to be improved by experimenting and trying to model something concrete. In that way, it is more easy to figure out what works and what is needed.
I discovered that the whole object needs to be selected as a FF group. If you only perform FF on a part of the object (for instance the neck of a glass) it will break contact with the rest of the object (loose faces, holes etc...).
Being able to just select what you need transformed does seem the way to go however as the FF operation takes less long (less geometry to FF) and the rest of the object stays untouched.Here's that experiment I am doing (the resulting mesh is dirty though):
