Hello,
I have a lot of images showing some coloured areas.
I want to use GH to retrieve the edge curves of every area.
I know, how to do it in Photoshop, for instance, but I want to do it in GH as these curves will be used in Rhino. And I really have many of them.
I am attaching the input image and wished result. 
Any help would be greatly appreciated!
How did you get that ‘wished’ result? Did you trace it manually or used a vectorizing plugin?
both plugins: Nautilus, by (@laurent_delrieu) and Graphic+, by (@DavidMans) offer such tracing algorithms. And if your input images are relative simple in terms of colors, you could try Bitmap+ to extract by specific color and outline
Thanks @Chris37,
Rooster plugin seems the best here
Vectorize is surely also a good option (in Rhino)
The best I can do with Nautilus was the use of Mesh Iso Split
manually drawn
thanks so much!!
I had a stab at both tools but the quality of the results isn’t perfect!!
thanks
