FANCYWIRES

FANCYWIRES is a Grasshopper thing

CHROMAtex.me

Another SOFTlab production!  A sucessful micro-financing fabrication site-specific gallery installation.  And for once reality is shinier than the rendering (thank you, glossy photo paper).

For a bad-ass time lapse video and sexy pictures of the completed installation go to the SOFTlab website.

For a web-based interactive 3D model of the project visit the CHROMAtex.me project website.

For gory details of the design, fabrication, and construction process check out the Kickstarter project updates page.

For all the dorky details (like the final GH definition and Rhino files) go to this lab post.

And if you’re in NYC go to the bridgegallery and see the real thing!  On display until September 26th, but may be extended by popular demand!

Wall + Beer = Biergarten

A renovation of an old gas station into a biergarten (translation: beer garden) by R+L is now open for business in Brooklyn, just in time for summer (and of course Oktoberfest).  Go check out Loreley if you’re in the Williamsburg neighborhood.

The waviness in the background is a hand-built parametric undulating brick wall.  Hopefully I can now dig-up the definition and post it…

Single Line Font

Of ongoing letterly interest has been finding a single line font for use in various fabrication fun.  We’re still looking for a truly GH compatible solution, but in the meanwhile here’s a hack of a hack that works with at least one machine tool font.  The true type fonts (there seem to be five floating around) can be found here among many other places.

Credit must again be given to Giulio of Grasshopper Tools in C# and specifically txtLines (the link on the page is dead, but you can still get the source definition from this direct link).

Label with care.

Multi Source – 2 Ways

Here’s a very basic definition that demonstrates the power of data trees and [Pull Point] or [Closest Point].

From a basic 5 x 5  point grid it will determine which of those points are closest to any number of referenced points.  Something like this could be the basis of an attraction/repulsion type definition.

Smoooothing

This example is rather contrived, but if you can exert a high degree of control over the creation of meshes it’s possible to get some nice topological smoothing.  The base geometry of the second image is composed of all quad faces.

This definition uses WeaverBird 0.2 components (thanks Giulio!) so you’ll have to install the plug-in first.

It’s pretty easy to make this geometry go wacky and if the smoothing level gets cranked up too high you might crash GH so be careful, but break-a-leg.

Pillow Talk

A (top secret) project in the very early stages, using quick GH studies for both rationalization of the structure and modeling of  ETFE pillows and their frames.

More on this later when it gets off the ground…

Project-o-Matic

A WIP based on the ever-popular Make2D command in Rhino (but really I just wanted a reason to draw some dashed lines).

How does Make2D work for NURBS objects?  I have no idea.  A cursory Google search leads me to believe it might, in part, be based on render meshes and surface normals (pointing towards or away from the viewpoint).  However there must be more to it because that doesn’t really explain how hidden lines are generated for NURBS surface edges.  And clearly objects like cylinders and spheres are special cases.

This definition only works (sort of) with closed, faceted BReps.  I was going to try to work with meshes (and I may still) but converting referenced NURBS geometry to mesh geometry in GH is a bit uncontrollable.  I also think this definition is a kind of fake way to go about this.

Actual Make2D results are at the right and you can see obvious problems with the cylinder.  Back to the laboratory.

Bang Letter

I’m not sure I would have followed the same procedure if I started completely from scratch, but just when you thought it couldn’t get better…  Exploding letters!

One little caveat, no symbols comprised of more than one piece (sorry all you !?%;=:ij lovers, but ” lovers you’re still in luck).

If you look under the covers I have an uneducated hunch that using [Trim with BReps] allows the definition to load / update text faster than [Inside], but as a result I had to do some crazy tree work.  Somewhere in there I also did a little VB.NET (still learning).

One might ask, why are are you messing with BReps anway?  It’s just stupid 2D letters.  Well, look at the B, A and R above.  They have internal openings, not just single boundary curves.  That makes imposing a uniform point grid properly on the letters a bit tricky, thus surfaces and BReps are your friends.

If I had more energy I would make a video, but you get the idea.

Happy shooting.

Bang Text

As a logical extension of my current fixation with text and circles, exploding circle packed words was clearly the next step (obviously).

Using a counting timer, the words are setup to “explode” when hit by a “bullet”.

The use of txtLines and theEngine again comes from Grasshopper Tools in C#.  Idea shamelessly ripped off from Flash work by Nullthing.

Set a Rhino bullet and fire away.

Golf Ball

So a looooooong time ago (back in the list only days) I created a definition based on an example from RhinoScript 101 (Page 63) for packing circles on a sphere.

Well, I can’t find the file and if I could it’s probably too old to be readable.  So I created the definition again this time using data trees (which is more in the spirit of the original script anyway).

You can generate circles based on their radius.  This works pretty quickly.  The bottom image has 31,295 circles.  No sweat.

You can also (because why not?) make a golf ball type object.  This works very slowly and it might crash your computer.  The golf ball image has 370 dimples.  Take a coffee break.
