Andrew Heumann replied to Lawrence Yun's discussion How do I "reduce mesh" via python?
"You might get some minor benefit by writing the Python script to work on a loop instead of on single items, but multithreading will not help you here because it's so dependent on operations in rhino. My guess is the c# script is your best bet…"

Andrew Heumann replied to Lawrence Yun's discussion How do I "reduce mesh" via python?
"The reason this script does some things in a seemingly strange way is to get around the fact that the Rhino SDK does not expose the reduce mesh functionality. In order to use it from Grasshopper, you have to 1. take the GH mesh and bake it into the…"

Andrew Heumann replied to Anton Szilasi's discussion Creating custom display graphs for grasshopper canvas
"This is not an easy task, and I would think it would be next to impossible with ghpython - you'll need to compile a custom .NET component to customize its appearance. Here's my (rough and probably incomplete) short list of the things you…"

"somehow that message got cut off funny :) Sounds strange - but it could have something to do with where the light is defined to begin with. Try creating the light on the world XY plane before you reference its guid. If that doesn't work, can…"

Andrew Heumann replied to Daniel González Abalde's discussion Wish - Brep Closest Point with output plane
"Yeah, this is a strange behavior of RhinoCommon's own "Brep Closest Point" function. I've modified the script to get around it. Hopefully this is closer to what you need. "

"this is a method David removed from the grasshopper code base... the developer of whichever plug-in is causing the error will need to update the code to not use this method. Any idea which plug-in it is?"

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.

Hey man, could you share the definition that Daniel share with you to make rigid origami stuff with Kangaroo?
