"is galapagos really the best way to do this? There are linear-time algorithms to find the smallest circle that bounds a set of points. attached is a definition that (I think...) finds the smallest circle around a set of points in the xy plane…"

Andrew Heumann replied to Ramon van der Heijden's discussion Cluster input removes empty branches and messes up tree structure
"This is certainly a bug - and an annoying one at that. I typically rely on a short script that adds nulls to every empty branch - then if necessary I can clean the tree once inside the cluster.  private void RunScript(DataTree<object>…"

write multiple lists to different locations in a sheet?

Is there a way with bumblebee to write to multiple locations in a sheet, with different data? Often I want to write, say, the 4 lists I have in 4 branches to 4 different columns that may or may not be adjacent to one another. Is there a way to do this?See More

Danny Boyes replied to Andrew Heumann's discussion Difference between Trim Tree and Shift Paths
"On the whole I don't see any real difference between the two except Shift Paths will do both Negative and Positive with differing results. With a path structure like {A;B;C} Trim Tree will go {A;B} and {A} with the inputs 1 and 2 But Shift…"

"also, if this behavior bothers you, you can disable extrusion objects altogether with the "useExtrusions" command. "

Andrew Heumann replied to jorge prado's discussion Grasshopper build 0.9.0076: Surface will not load
"What you've got there is technically an extrusion, not a surface - you can load it into a BRep component and then reference it in GH, or you can explode it in Rhino to turn it back into a surface before you reference it in. "

Tweet2Form: GH-Powered Formalist Tweetbot

I just finished putting together a beta version of a little project. It's a tweetbot powered by a grasshopper definition. The bot transforms a cube according to a series of operations you specify, and then tweets a picture of the resulting form. There are currently 10 formal operations that the bot understands:

split

bridge

stretch

scale

shearA (Shear angular)…

Find and Replace in Grasshopper Documents

originally posted here

Since David Rutten added to GH the ability to set a default text panel background color, I’ve had my panels set to be white instead of the default bright yellow. But in all my old definitions, the panels remain yellow, and it drives me nuts. I was going through and changing them manually when it occurred to me that there was a much better way, based on a trick I saw David mention in a…

Hi Andrew,
I see you are quite fluent in RhinoCommon.
Was RhinoCommon SDK your only source for learning it?
Thank you.

hi Andrew, I actually have a big problem trying to import rhino text objects to grasshopper to create a points cloud; fortunatly I found the solution in one of  your old posts...http://www.grasshopper3d.com/forum/topics/using-number-text-objects-for?commentId=2985220%3AComment%3A168316

but it doesn't work for me... certainly because of the new version of GH (0.9)... I'm using Rhino 4. I really need your help on it, I didn't find other solution anywhere else and don't know anything in scripts...  Thank you so much !

Hello Andrew;

Great work on the Origami simulation showed here: http://www.grasshopper3d.com/video/rigid-origami-with-kangaroo-1?commentId=2985220%3AComment%3A150253&xg_source=activity

 

just wondering if you can share the definition?

hi Andrew,

i need help editting the qvoronoi defination by demitrie. When ever i give my points rather than the random points, the qvoronoi turns red and the defination fails to work. Also that i need to give the bounding box to be my site. how is that possible? Its my thesis year and im running out of time. I am new to grasshopper and seek guidance. Thankyou.

Cool!, thanks for sharing concepts :D I'll try that :) 

 

Best.
