[Plugin] SketchyFFD (Classic)
-
well, that did the trick for me. thanks, Glenn.
however, there are still some issues sometimes. like that a transformation isn't applied to certain parts of the geometry.and I have got two questions/suggestions for improvements for a future version:
-
when you undo an action, the deformation, that has been applied to the geometry will be undone. the changed position of the control vertexes however is not set back. thus, when you undo an unwanted deformation and then move some control vertexes again, the old (undone) transformation is simply added to the new transformation)
so my question is: is there a way to undo the repositioning of control vertexes alongside the undo-process of the geometry? -
when you deform a group, then delete the lattice and then create a new ffd lattice, the array of control vertexes is shaped around the old position of the group. in order to correct this you have to explode and regroup the geometry.
I guess there is now easy way to overcome this problem. but if there was a possibility the plugin could reevaluate a groups position/scale, before creating the lattice, that would be cool.

Yeah !, that modification came just in time. I needed it for work. Modeling a boat.
Great work.As for the undo, for now I undo twice, one for the geom and one for the vertices. Seems to work fine.
-
Is Chris no longer maintaining this?
-
hey Glenn,
marvellous! now it works like a charm. a new matrix is always reliably adjusted to the group's dimensions and - for me even more important - undoing an operation effects geometry and control vertexes at the same time!
thank you very much for improving the script, Glenn
-
I do have a question about the workings of this plugin.
is the deformation a gradual process? (each change I make with the matrix adds another deformation to the geometry, therefore the order is important)
or is it only dependent on the matrix's final state? (no matter if i do 10 changes or a hundred, the final position of control vertexes is important)
because if the latter is the case (which I hope), you could - in theory at least - write a mighty modifier plugin not too much unlike 3Ds Max's deformers, where you can assign various preset-deformations to an object.
these modifiers are attached to the group, can be switched on/off or their attributes can be adjusted.
also you can add several modifiers (like a 'twist', a 'bend', and a 'squeeze' modifier). then the order is important (whether you twist or bend first), which of course can be changed later too...I don't want to know how difficult/impossible it is to write such a script. but just imagine the capabilities! you would add a whole new level of non-destructive controls to SketchUp

OK, here's the latest update. This one should fix the problems with control points and subdividing being misaligned with the deformation group.
I'd appreciate any feedback to let me know if it's working well.

Maybe better to create a new thread - so the download is at the start of the thread - not buried somewhere randomly in between. If you do that I'll tab this one obsolete and add a link to the new version.

Hi guys,
I've installed the SketchyFFD plugin by dropping it into my plugins folder but cannot locate it in SU. How do I access it/ turn it on?
Thanks.

Hi and welcome
. You will find FFD in the context menu (right click). Oh, and remember that this plugin works on grouped geometry. -
Hiya,
Sorry for effectively bumping this post for everyone again but I'm having a real problem getting this plugin to work so was wondering if someone could possibly help?
I tried by creating a simple cube, grouping everything and then running the FFD 2x2 on it. I see the point grid appear but then I'm not too sure what to do. I can't select points easily and when I do all that happens is that the points move but the object doesn't change in any way at all, just the points move
Has anyone ever seen that before and knows what might be causing this?
Many thanks for any help on this.
Best wishes,
Mark

Once you have made the cube a group, right click and select the FFD you want, then click on one of the small black crosses to edit the form. Now you can move, scale, rotate one or multiple crosses to deform the shape.
When completed close group and delete FFD transformer group. -
Here is a video of what I mean.

Thanks. I've finally got the mesh working although sometimes it doesn't always do anything. Probably me being silly or something though.
Off to give some of that a try now.
Many thanks for the help on this.
Best wishes,
Mark

Great! A little confusing, but great!
-
Cool! It is very useful and amazing tool. Thanks!
-
thank you

ThankYou for your Plugins.

Hi to all. Having a problem when I make an FFD Patch.
Here's the message:

Hi guys, thanks for making this plugin!! I'm new to SKP plugins but experienced enough with sketchup.
I have had a quick play with this tool, first on a cube it appeared to do nothing, then on a dome and it worked.
Could people explain, where and when this tool would best be used? I'm currently think for floors, but then we already have sandbox.
Thanks for your advice.
-
excellent plugin! this combined with soapskinbubble and the sandbox make life in sketchup so much easier

This plugin is not working in Sketchup 8
