GRID DISTORTION
-
It appears in context menu: right click on a group-->FFD...

The plugin won't appear in plugin window.
Right-click on a group and find FFD in the context menu.
Carefully read the original thread, it is not a so easy plugin as you don't see deformation in real time.
So, save before use and practice a lot.
It may be easier to draw this thing by hand with Fredo6 bezier tools if you want to reproduce the exact thing your picture shows.
Up to you to choose. Good luck and fun -
i'm kinda thinking there are two different things going on in the thread.. the tree example is different than the examples i posted..
meaning, the grid work ala vasarely is meant to be viewed as a 2D piece more or less from straight on..
the tree is more of an optical illusion thing though.. (and maybe it's arguable that the paintings are also optical illusions but the tree thing is more gag like.. the punchline or hook or whatever is being shown to you precisely so youre not left wondering or interpreting the piece yourself.. it's main purpose is to leave the viewer visually disoriented in a realm not so different than that of a magician.. you know?)
anyway... it seems as if the way to do the tree drawing is sort of a combination of what gilles and dave both showed earlier..
draw the thing in 3D.. something like the sanbox method which was shown.. then align a plane in such a way that when the object is draped, it will look like the 3D version except it's flat.. something like what dave was showing..
set up a scene so you can continue to return to the same perspective..
something like that

OK Jeff I have made one using the sandbox tools and I have tried draping it on to another plane. This is where I am coming unstuck. I don't seem to be able to align a plane that it will appear to be 3D when its looked from above.
Any chance of an example please if you have the time?
Thanks

Think about the physics of what you want to accomplish. The illusion will really only work from one vantage point. Figure out where you want that to be and determine the angle between your 3D mesh and the viewer. Use that angle, or actually its compliment, as the angle between the mesh and the plane onto which you'll project the image.

I recall writing a short script to 'project' objects' outlines onto the floor-plane for this kind of thing ? ........ http://sketchucation.com/forums/viewtopic.php?p=320466#p320466

Wow TIG thats a really good plugin.
I have now produced a distorted grid and have exported it as a dxf into my CAM software.
There are a lot of open vectors which I can join most of them by using the 'join' tool in the CAM software. There are still open vectors and when I further try to join these, the lines become broken.
Is there a way that I might be able to export this file so my CNC router will be able to cut single lines in the grid both vertically and horizontally?

Some screen-shots, and an example SKP file [perhaps simplified?] might help..

I don't know your software so i don't know if this will help but...
maybe go to top view then window select all the lines in one direction then delete leaving you with only the lines in the Y direction.. recurve/curvizard/weld the lines then group them.. do the same thing for the lines in the other direction.. you can now try to feed the cnc the non intersecting lines..another problem might be that the angles between various segments are too severe for the software to recognize it as a single curve.. if that's the case you might have to use a plugin such as curvizard or BezierSpline which can smoothen out the lines and make the angles less severe (ie- add more segments)..
not sure though..
(and not much time to give more thorough examples.. sorry) -
Thanks for that Jeff.
I have downloaded the weld plugin but I don't seem to be able to weld the segments of the lines together for some reason.
I did separate the lines into parallel and horizontal sets and exported the two sets into my CAM software. I joined the vectors in both sets and will have a go at routing them and let you know the outcome.
Thanks again for you help.
