David Rutten replied to Serge Neuman's discussion C:\dev\grasshopper\1.0\root ... how to install Grasshoper SDK?"That is very strange. When the Memory Load option is checked, it means that the GHA file is first loaded into RAM as a byte-array, then loaded from RAM. This gets around certain loading security issues, but it's not a good idea when you want to…"
David Rutten replied to Serge Neuman's discussion C:\dev\grasshopper\1.0\root ... how to install Grasshoper SDK?"Hi Serge,
the Grasshopper SDK is Grasshopper. It's the same files. When you want to debug your GHA library, you should make sure that your library is loaded directly from disk rather than via the memory.
You can use the…"
David Rutten replied to Sébastien Mennetret's discussion Rhino/Grasshopper as slave on server"We have no plans in this direction. We're so busy with Rhino5 that nobody is willing or able to think about these kinds of things. There's also severe legal issues to consider. Rhino is typically licensed as a one-use product. You buy one…"
David Rutten replied to Alex Baalham's discussion Controlling longest list behaviour"I'm guessing the problem is creating the preview meshes. If your Rhino is paging at the same time because you're out of physical RAM, it really will take forever. Does it speed up when you switch off shaded previews?

David Rutten replied to Andy VanMater's discussion Path Mapper in (VB) code"Hi Brian,
DataTrees and IGH_Structures have been completely parallel types. This was probably a mistake, but DataTrees came later and I basically just copied the source for GH_Structure and tore out all advanced methods. Ideally GH_Structure should…"

David Rutten replied to steps79's discussion intersecting line and a curve"Hi Stepan,
I'm the developer of Grasshopper, therefore I typically use a version that hasn't been released yet, because as soon as I release 0.9.0001 I'll start working on (and with) 0.9.0002.
The files should open I think, although…"

Daniel Piker replied to David Rutten's discussion When is the next release of Grasshopper?"This all sounds great, looking forward to the new version.

David Rutten replied to Yannis Chatzikonstantinou's discussion Default Input for Geometry / Generic Parameter"Hi Yannis,
yes, both Generic and Geometry derive from GH_PersistentParam which can store internal data. There are however no overloads for adding this data in the Register_XXXXParameter methods. You'll need to get the parameter afterwards,…"
David Rutten replied to Meagan Wood's discussion Z Axis Planes/Drawing Curves"Typically in Rhino you always draw on the grid. So if you want to draw vertical objects, you're best off drawing in the Front or Right viewports. You can also adjust the Grid in the perspective viewport to be vertical, but that's more…"

David Rutten replied to steps79's discussion intersecting line and a curve"You'll need to convert your Line into a Curve first, as Intersect.Intersection.CurveCurve demands two curves.

Evolutionary Principles applied to Problem Solving
This blog post is a rough approximation of the lecture I gave at the AAG10 conference in Vienna on September 21st 2010. Naturally it will be quite a different experience as the medium is quite different, but it my hope the basic premise of the lecture remains intact. This post deals with Evolutionary Solvers in general, but I use Rhino, Grasshopper and Galapagos to demonstrate the topics.

Muhammad Hissaan Awaiz said… dear David,
I am trying to use data from Ecotect by using Geco and trying to optimize my facade to an optimal shape against the sunlight where it recieves the least abount of red on it.
I would like to know if there is a way to convert the mesh colour from RGB to some usable value. Specially the red colour? So that I can link it with galapagos and find an optimal form?

Archi_made said… Hi David,
I'm using DIVA for Rhino and Galapagos to generate architectural solutions. I'm using the Last version of GrassHopper. I have some troubles with the Galapagos parameters as Max stagnant and Population Number and also the Runtime limits. The problem is that Galapagos dont respect the values given to these parameters.(Screen shots)
Best regards,
Anis

Hi David,
Im trying to export my geometry from grasshopper as *.obj file and import it to rediance. what i need at the same time is to make a *.map file which assign the material of each object for the radiance, so i need to get every single objects name to compile the *.map file and i don't know how should i do that. can you help me with the script to extract all object names from vb script component? then i can use them in my new file. many thanks in advance,
hamia/

Huzefa Ali said… Got it. I just had to flatten the contour output. thanks anywways. Can you tell me how i can add 2 points at the end of each mesh to get a lofted closed brep? I know how to do it on rhino, but how do i add oints with the curves in input to get the closed brep?
