[Plugin] SketchyFFD (Classic)

CPhillips

Ah. Dealing with subgroups gets a bit tricky, but I will see what I can do.

remus

I look forward to seeing what you come up with

plot-paris

a very interesting idea, remus.

but what happens, if the deformation is a bit more complicated?

imagine you want to alter the shape of the first object (on the left hand side of the image). the red plane is a group within the group of the green bowl.

if FFD behaves like in your sample, it would look like the second form - the bowl is deformed and the red plane has to decide, where to stick to the connecting geometry.

or should the group within the deformation object be deformated where it is necessary in order to keep contact to the connecting geometry at every common edge?
but would that make any difference to simply enabeling FFD to alter nested groups no matter how deep the tree structure goes?
it probably would, because the group's content would only be changed, when absolutely necessary.

I am confused now...

remus

I was thinking of it mainly in the context of using it to rig models, so i didnt really think about situations such as the one you mentioned.

Basically ive got no idea how it would behave in those sort of situations, i suppose thats up to chris' discretion, if the idea works at all.

If what ur saying is that the group should be deformed too but still remain a group den im with that

simply awesome!, it's sure a big help!, thanks a lot!

Thanks man-it is really inportant emproovement for SU. Google is too poor to do it
BUT! it does not work for my favorit 3D soft- AtLast Sketch Up 5 Why?

I think it should. But I dont have SU5. Can you open the ruby console try it and see if it prints any errors?

Thank you for reply! This is console message:
Error: #<NoMethodError: undefined method add_observer' for #<Sketchup::ConstructionPoint:0x6cab320>> C:\Program Files\@Last Software\SketchUp 5\Plugins/SketchyFFD.rb:377:in createControlLattice'

To my knowledge WebDialogs and observers are not working with SU5

Hi..
I am trying this ruby but doesnt work. I create a simple circle and pull it to give it a height. i then select everything and create group. I then select group and right click and it lets me do 3x3 etc point cloud. When i go into points group and move some points and close group and then right click on geometry group then i dont see update FFD tool. Can someone please help?
I am using sketchup 6 pro

thansk in anticipation.

The ruby works as advertised. I think you need to revisit your steps and have a careful look at how to use the ruby again. Make sure it has subdivided geometry to work with though.

My deformations are not auto updating themselves. Would anyone happen to know why?

remus

It might just be taking a while to work out whats meant to be happeneing or SU might be taking a while to display the deformed geometry.

Hi,

I have downloaded your program sketchy FFD and have put it in the plugins folder. I see it in sketchup when i right click but when i apply it to a group i do not see the update ffd option. can u please tell me wot I'm doing wrong? thanks

remus

If youve got the latest version you shouldnt need the update option, it should do it automatically.

Not always. as a matter of fact I would vote to get the 'update' button re-instated, just for the cases the auto-update doesn't work.

CPhillips

Yeah, the update menu option was removed when I figured out how to auto update. Ill remove it from the post.

I can put it back. But I would rather fix the bug that keeps auto updating from working. Can you send me a model that the FFD doesn't auto update I might be able to figure it out.

Wonderful plugin, thank you very much. If I do anything useful I'll try to upload it . . .

cheer man u are rockin
for base users like me ur genius
go on

REGIS

Hi CPhillips, it appears that your very great plugin doesn't work within google sketchup 7.
Any idea ?

Thanks in advance

cheers

I'll post an updated version tonight.
