Day 72 - Back in Silicon Valley

Venerdì 08 Giugno 2012, 23:38

After six years from my first trip here, I came back to where it all started! Revolution, at the Computer History Museum was an amazing show just in the middle of a God blessed land, even if a lot of startups around closed compared to 2006.

Some pictures if you want to

GreenSpider 1.0

Martedì 22 Maggio 2012, 09:10

GreenSpider release 1.0.2 is officially out for beta-testing, it can be downloaded here.

GreenSpider is a plugin developed by Simone Garagnani for Autodesk Revit 2012, taking advantage of .NET libraries 3.5 and C# programming code. Once installed through downloaded file, GreenSpider can be accessed in Revit mass modeling environment.

In order to import geometries, especially from Rhino+Grasshopper or laser scan segmented and decimated point clouds, a file called points.gsp has to be prepared and copied in GreenSpider directory (C:\greenspider, by default installation). GSP is a plain text file format where XYZ numerical values representing geometric vertexes are separated by semicolons, while commas are used for decimal marks.

This plugin operates Metric conversion for Revit so GSP values are required in centimeters.GreenSpider is still a prototype so it’s possible to run two commands identified by two different icons in Revit: GSpoints and GScurves. The first import the vertex point cloud, while the second traces a spline interpolation among imported points, in order to build surfaces after several points.gsp imports.

GreenSpider searches for points.gsp file in proper directory. A little piece of software, called GreenSpider Translator and developed by Simone Garagnani as well, can be downloaded and installed in order to convert XYZ vertex files with no normals into the correct file format used by GreenSpider plugin into Autodesk Revit. GreenSpider Translator opens files, recognizes them, then parses them in correct format, copying a translated file renamed points.gsp into C:/greenspider, where the plugin can easily find it. Importing different set of point clouds is now easier since the Translator can be reset each time, erasing previous GSP files already acquired by Revit.

Here’s the GreenSpider introductory page.

Release Note for old systems: GreenSpider r1.0.2 has been coded for Autodesk Revit 2012 running on Windows 7 machines. The installer could fail copying files on old computers running WinXP (not supported by GreenSpider but working flawless with its features). In case of troubles, please continue the installation process until the end, regardless of warnings and error messages. Then copy this file in your C:\Documents and Settings\USER\AppData\Autodesk\Revit\Addins\2012 directory, this should fix GreenSpider icons into Revit 2012.

Day 60 - Journal activities delayed

Lunedì 30 Aprile 2012, 05:31

I scheduled for today my blog page writing about CalDay, last April 22nd, but I preferred to keep my attention focused on GreenSpider v1.0, leaving my Berkeley chronicles for another day. I spent a couple of days figuring out how to make my Revit plugin work and I found some satisfactory help on priceless Jeremy Tammik pages. Even Dermott Mcmeel video has been inspiring. It took me several years to decide learning some C and Berkeley's scientific spirit, favouring a deep curious look into things, made my day!

Here's my first GreenSpider introductory page.
