C# Example: For-loop in parallel execution and the "lock" statement
5 Replies

Hello,I noticed that a lot of people coding with python are using the parallel- library, whereas I never see people using multithreading in C# or VB.This is probably because most people don't know…Continue

Tom Jankowski replied to Gaurav Chauhan's discussion Surface from .STL/.OBJ
"Hello, there are tools out there, directly converting from obj to nurbs can do t-splines, if you own it. But probaly not because you would have known it then. You can't purchase it anymore so forget about it, probably Fusion360 can do it…"

Tom Jankowski replied to Tobias Hackbeil's discussion how to make fillet with ASTools? in the group Advanced Surface Tools
"Hello, I am very busy this week, so I won't be able in providing an example very soon. Eventhough ASTools is capable of doing this, I do not recommend to fillet by Grasshopper if not really necessary. It will take much more effort…"

Tom Jankowski replied to Manoo Ard's discussion Bug in python
"I don't think so. but without data its hard to tell. How many m's are connected to your component? If you connect a series of numbers and you toggle item access, your component is repeated n times..."
Tom Jankowski replied to Razzo Nir's discussion move and intersect separate surfaces (if condition)
"Hello, I made this short c# script, which basically does the same as your script except that it does your definition iterative. You could do the same with native grasshopper if you use a plugin like hoopsnake or anemone for the looping…"

Tom Jankowski replied to John's discussion Parallel.For in C# component crash Rhino.
"very nice, Panda. But are you sure that Rhino.RhinoDoc.ActiveDoc.Objects.ModifyTextureMapping(guid[i], 1, textureMapping); automatically gets locked, without using the lock statement? @ Tom As Peter already said, multithreading is not as…"

Tom Jankowski replied to Benjamin Felbrich's discussion Does DA.GetData make a copy?
"Oh okay, I was wrong here. I never was in need of creating an own parameter object types deriving from the interface IGH_Goo. I also always retrieved information from my input and implement my own datatypes, so I never come into the…"

Tom Jankowski replied to Benjamin Felbrich's discussion Does DA.GetData make a copy?
"Hello, usually classes, compared to structs or primitive datatypes, are passed by reference. However Grasshopper needs to copy them, because otherwise you couldn't have two different states of an class instance being existent at the same time.…"

Tom Jankowski replied to Carina's discussion Smooth connection between more than 2 curves
"Hello Carina, If Meshes are okay go for the advices of Anders. There are approaches as well for meshes, some related to kangaroo and relaxation. Vincents Soler did also something, which can be found on the forum. If you are looking for a nurbs…"

Tom Jankowski replied to pierre m's discussion Beginner problem
"hello always nice to see people starting with coding here. This will actually simplify a lot for you in the world of grasshopper. Anyway,here is one way on how to rotate a line. I made it in all three languages in order to prove, that all these…"

Tom Jankowski replied to Maciej S's discussion Closed curves into surface
"Just in addition to BB's answer: He basically uses the hidden Rhinocommon method surface.CreateRollingBallFillet(...), which creates a NurbsFillet. The problem with this kind of fillet is (and that is why it is hidden): it doesn't align…"

Tom Jankowski replied to Maciej S's discussion Closed curves into surface
"No!  Hardly anyone in the Rhino or Grasshopper forum knows much about high quality surface modelling (class a etsc). Rhino isn't the best tool for freeform modelling, compared to Icem Surf or Autodesk Alias. Filleting in Rhino is a hell,…"
