    • RE: Visual Algorithmic Design for Design Applications (A Rant]

      Well, boss, you know where I stand on this. I've posted links to Grasshopper before...perhaps you have some favorite examples (Youtubes or screenshots) to show what we're talking about.

      It was just brought to may attention by one of my former students that this project for the Eiffel Tower (which is controversial, because the designers let it be mistaken for a real project, and only later reluctantly admitted this was theoretical...and a publicity stunt) was created using the sort of modifiable tool Diego is describing.

      http://www.serero.com/projects/eiffel/images/integration-2.jpg

      Let's add another category of software to Diego's list: music, video, and performance art applications, such as

      VVVV (freeware, mainly for video manipulation)
      Max/MSP/Jitter (originally for music "sound design", with added video capabilities)
      pd~ (open source music/video "multimedia performance" software from the same developer as MAX; graphics capabilities added with gem)

      And don't forget Lily, which is a free progamming tool that allows you to create plugins that run within Firefox.

      Anyone up for helping me create a noded visual progamming language interface in Ruby for SketchUp?

      (Diego isreally my boss, incidentally.)

      By the way, I'm told that if someone contacts Google SketchUp's support team with a question about SU on Linux now, they are directed to look at this thread!

      Wow, seems like our pro licence money is hard at work.

      No, they're just being nice. First they tell you that they simple don't have the resources to make SU available on major Linux distros, but if you insist on trying...

      Actually, everything here works on the free SU as well. In fact, that is easier to install because it doesn't insist on a pointless download of .NET to run Layout (which doesn't work on Linux, because .NET has never been ported to Linux by Microsoft).

      Be sure to scan free font downloads thoroughly before unzipping them...I have heard that this sort of thing is a common vector for distributing viruses.

      I personally haven't found anything like that, but you always wonder if it could be that my AV program just missed something...

    • RE: ParaCloud Generative Modeling

      Ask my boss, Diego Matho, who loves this kind of thing and already mentioned this program to me. I believe our school even has a couple of licenses, although I've never used it. Diego? Are you out there?

      Right now, "generative modeling" is all the rage in academic architecture and with students. All kinds of CAD and modeling programs have instituted features like this, which were originally only available (as far as I know) through hand-coding, then through an expensive accessory to Bentley Microstation called "Generative Components." But now the concepts are trickling down everywhere...I particularly like the plugin for Rhino3D that allows this, called "Grasshopper", which is free and scripts with a node-based visual programming language.

      I think the whole fad is symptomatic of a kind of serious semantic problem in architecture...that there is no meaning there that can actually be objectivelywritten. What does a work of architecture mean? Not what-is-it-for, but what-does-it-mean. If you can come up with a meaning for a work, are you very sure that someone else would automatically come up with same meaning without your help? Of course not.

      Generative architecture almost answers the question, or rather confuses the issue enough to shut up a lot of people asking it. You set up a set of rules (written, one way or another, as a formula...at this point in the model, this item goes here, then this one attaches here, then this one rotates so-and-so...and then *voom!*you have this wild form for your building, be it a funky spiral skyscraper or a stadium shaped like a bird's nest. And if some challenges you on the shape, you the architect can blithely respond, "Well, that's just the way the generating formula worked out." It's not your fault that it looks like, it's the working-out of some fundamental mathematical law, a force of universal truth, blah blah blah. And what does it mean? It is the realization of a mathematical formula or method. There is more than a bit of specious disambiguation here, as the processis suddenly substituted for meaning. But it gets everyone off the hook...architects (especially young ones, besotted with form) no longer have to justify themselves or their design in the same way, and by surrendering attendant design development to a formula they save themselves all kinds of effort in having to work out or justify the consequences of their initial design idea.

    • RE: Bonzai 3d

      I saw the demo at the AIA convention a few weeks ago. Then the owner of Auto-de-Sys, Chris Yessios, nearly slugged me after I started pointing out--in answer to his (slightly contemptuous) questions after I was identified as an instructor of SketchUp--how I would do all of those things he was so proud of in his new baby with plain old SU, or with a little Rhino if I really had to. If I had known he was the founder and owner of the company, I possibly wouldn't have said anything. (Note to self: read the name-tags in the future!)

      It's a stripped-down version of Form-Z with about 80% of the functionality of the whole thing, and a UI that looks like SketchUp but functions with much of that same old ponderous Form-Z goodness. It does read and write SU files, in case you're interested, and it costs about as much as a new license to SU Pro. They mentioned NURBS, but I saw nothing in the demo that looked remotely like the NURBS capabilities of, say, Rhino or MOI. I have the sense that Bonzai is not so much a full application as a kind of marketing ploy masquerading as one: the idea is to convince you to eventually shell out the full $2500 for a license to Form-Z because you need that other 20% functionality.

      Mr. Yessios was particularly vehement about his program's ability to write STL files that would work well with Z-Corp printers. Over and over, he kept saying, "...and SketchUp can't save STL files. It can't save STL files. It can't save STL files!"

      See you
      Mick

      Usually SketchUp starts having problems with export resolutions greater than 4000 pixels in any direction, independent of platform, unless antialiasing is turned off, under Options in the export dialog. You might see if that helps; otherwise you're probably right about the 64-bit version being the issue, although I can't imagine why that would be such an issue.

      Quite a few people on this link have been able to run SU on various other distros than SU; if you have the time and partition space, why not test one out, or for that matter make a partition for booting Ubuntu 32-bit? At least that would be one way of isolating the problem.

      If I can find the time, I'll download the Ubuntu 64-bit and see if the problem is there for me. Might be a few days, though, until I have that much spare time.

      Just out of curiosity, Mick, do you generally see much performance improvement with Ubuntu 64-bit, outside of the SU problem? What applications show the most difference, if you do?

      My 20-month-old daughter saw this on the screen of my monitor (which is 24", so the head is almost real-size). She's now hiding behind a chair repeating, over and over, "Scary! Scary! Scary!"

      Why not, Lewis?

      The softwares have characteristics and different capacities - MoI is a modeller of NURBS. But we know that a great deal of the demands here trying to turn SU into a tool more..."organic". And the scripts follows: SubD and smooth, Soap bubble and skin, FFD etc.

      SU and MoI there would be good partnership?

      Thank you for your attention

      Feel free to discuss integration of the two, as I said. MOI is quite a nice inexpensive little portable program, and I have a copy, but it's not SketchUp. It is a NURBS modeler, as you have noted, and NURBS objects cannot be represented in SU, whereas SU-made meshes have limited functionality in MOI, much as they do with MOI's older sister Rhino.

      Whats the diffrence of nurbs and polygons?

      http://en.wikipedia.org/wiki/Triangle_mesh
      http://en.wikipedia.org/wiki/Nonuniform_rational_B-spline

      NURBS describe surfaces with an infinite U and V grid of Splines, rather like the way a standard plane could be conceived of as infinite number of parallel lines. A NURBS surface does not have to be flat, or developable, or manifold.

      I actually teach a course in this. Although they present more apparent freedom and surface accuracy (when the surfaces in question are not planar), NURBS modelers typically have a higher computational overhead, are more difficult to texture...and in fact are invisible and must be represented visually on computer monitors with meshes. For instance, Rhino 3D constantly redraws a simulation of its NURBS objects using standard polygonal meshes, which leads to an interesting problem sometimes: what you see on the screen is not actually what you have modeled.

    • RE: SketchUp and Rubies on Linux (yes, it works)

      While making these JPG tests, I decided to let Ubuntu update the NVidia GLX driver for my computer, and in fact most elements of graphic performance improved after a restart. Except in one area: when unselecting an object, or when closing a group/component open for editing, actually seeing the change on the screen is delayed until one moves the camera or starts another operation.

      That's surprisingly annoying with a complex model full of nested components, and I don't think it was happening prior to the latest batch of updates!

    • RE: SketchUp and Rubies on Linux (yes, it works)

      Just to make sure it works and no update has broken the functionality recently, I just switched over to Linux and did some JPG exports. In fact, for some reason, the export process seemed much faster than it did using the same file on XP. And this is a fairly elaborate model, with shadows and antialiasing turned on, at 3000 pixels in its longest direction (resized here with GIMP).

      conv15v3b.jpg

      Mick, you might want to check and see if your current Ubuntu installation can view or create JPG files using any application (try GIMP). I've never had to look for a library for viewing or writing JPGs on Linux, but it is a non-Open-Source format so perhaps you managed to not install it or delete it.

      Hi all
      Thank you all for helping me.
      I don't know... i have done exactly as lewiswadsworth said and actually i got my design imported in SU with only a few mesh lines that i successfully erased, but after that i've tried to import a little more complex item in SU and the result wasn't as good as the previous one...

      There are always too many meshes... It will take a hour to get rid of all those lines... ๐Ÿ˜ฎ
      And i've even selected the merge faces option in SU...
      Isn't there a way to send all those lines to hell without spending half the day? ๐Ÿ˜›
      Thanks a lot!!

      No, curving surfaces in SU will always be composed of multiple polygons, unlike what you see in Rhino or Solidworks (which have different methods of describing geometry). Your best bet is to completely select one of the screws (every part of it) and then Right-Click. In the context menu, choose "Soften/Smooth Edges"; when the window pops up, move the slider until the edges you want hidden are gone.Make sure you check the "Soften Coplanar" box.

      They're not really gone, of course; they've been hidden and the face-normal spread between multiple polygons so that the multiple-surfaces look like one surface on your monitor. If you turn on View menu> hidden geometry, you can see and select the smoothed edges and individual polygon faces.

      Sorry, that one works on the two Ubuntu boxes I have set up. However, SU6 has always had some weird graphics export problems...the other day I had a 3500x3500 pixel image fail, inexplicably, on a Windows box until I changed the export resolution to 3499x3499.

      Did you try the export with another image format, like PNG? Also, see what happens if you turn off antialiasing under options when you export a 2D graphic file.

      If you really want to test the file, post it to me and I'll try an export using SU on Wine on my Ubuntu workstation.
