GRID DISTORTION
-
Can anyone help me?
I want to create a grid and then distort it to create a 3D illusion of a tiled floor that is being pulled into a hole. I then want to CNC cut the lines onto a piece of black or white laminated board to make an interesting piece of art..
Is there a plugin for this type of grid available?
Thanks for your help

Then use Slicer by TIG

Hi,
Thanks for your quick reply.
What i really want todo is to have a grid thats rectangular say 50 x 25 with rectangular squares. if you can imagine all the lines being elastic and a tennis ball being pushed into the centre. All the lines would be distorted following the indentation that the ball has made. This would give an optical illusion that the tiled floor was falling into the hole the ball has made.
Sorry to be so vague but I dont know how to explain it any better.

And if you want just a structure
Line2tubes by Didier BurA possible workflow
Restart with the form without thickness
Show Hidden geometry
Plugin Xline by Rick Wilson Aplly it twice
Keep only 3 Strips of lines, kill one full vertical line
Line2tubes by Didier Bur
Select all
Copy Rotate * 11
Have fun

Thanks for your replies.
I didn't explain what I would like todo well enough.

I would like a grid, say 50 x 25 made up of rectangles rather than squares.

If you imagine the grids lines to be made of elastic. When a tennis ball is pushed into the centre of the grid the lines making up the grid would be distorted and give an optical illusion that they are falling towards a hole made by the ball.
I hope this better explains what I mean.
Thanks

not really but i'll take a guess anyway
this?

Thanks.
Thats exactly what I want todo but I would make it a little more dramatic!
Can you tell me how todo this please.
Thanks again

i did that in rhino with its paneling tools.. to do it in sketchup, i think the best way would be to use thomthom's Vertex Tools plugin..
http://sketchucation.com/forums/viewtopic.php?t=29636
pretty fast/easy:
make a single rectangle with each edge divided into 5... array .. vertex tools soft select circle.. vertex tools scale via gizmo..you could also get some stuff like this out of fredo's CurviLoft plugin.. less simple but still doable..

Sandbox?

If I understand your request correctly, and I may not since it isn't yet 4 am and I haven't had my coffee, you are after a 2D grid that only looks 3D. Is that right?

Huhu
That I has never understood is why as soon as the first post there is not an image of what is wished!
A text can't say precise thing, there is ever interpretation!
With an image no problem, simple , speedy, perfect!
Bravo Gilles that is the absolute solution!
Even it's 2D gride wished just take an image of your sreen as texture!

Thanks again for your posts.
Yes Dave R I am wanting to achieve a 3D effect but have it in a 2D form. I want to cut the lines on a CNC router, so it will be on a piece of plywood hanging on a wall.
I will download thomthoms plugin and see how I go.
Another thing I would like to do with it is to cut out the individual sections and use them as tiles in a courtyard to give a very interesting effect on a scale of 10m x 5m.
Once I have this thing worked out I am happy to post the finished product including the dxf cut files.

You could use TT's "UV Toolkit" plugin to first apply the material to a set of facets in a grid, second "remember UV" then modify (distort) the grid finally "restore UV" with the plugin.
Though this tutorial is not about the same thing as it's about 3D, it would work exactly the same way:

I'm thinking Didier's Projection tools might be the ticket. I did something similar to what I think you want here.
In this case I drew a simple funnel shape with no faces.
Then I set a large rectangle below the funnel and tiled at an angle. I projected the edges of the funnel onto the rectangle.
Of course you want a bunch of rectangles to start with so you might use the Sandbox tools or Artisan or Vertex Tools to distort a regular grid as desired. Then project the edges onto the angled face.

That's a nice one, Dave! (with SU Pro, you could even export a 2D vector graphic of it)
Then of course, there's always the option to do it "simply" in 3D and export a 2D image of the view only...
-
I was assuming he wants some sort of vector output since he's going to CNC. Otherwise I would have suggested a simple 2D export. I suppose the PNG could be run through some other application to get vector lines.

After making the 3d 'black-hole' you need to project it [drape?] onto a flat surface.
This can then form the basis of the CNC data.
Since the OP seemed to want to cut alternate quads just a little to expose a different material then somehow he needs to pushpull then slightly down...
This is going to be the time consuming bit... unless someone writes a one-liner to pushpull alternate faces by -1mm and also alternate doing that in each 'row', so for any four sharing a vertex 0 and 2 are processed... [sdmitch??] -

this is the kind of stuff he's after.. grid distortions using point attractors and whatnot.. lots of this type of stuff going on these days..
