I’m finally getting into teaching myself Grasshopper and one significant task I want to figure out is how to extract a curve from a Raster file. I see there are tools like Vectorize and I believe Rooster used to be available but now isn’t. These tools produce an outline of the pixels produced by line width.
Are there any GH Nodes that are able to approximate the centre of a raster line and draw a curve like the in-built sketch tool in Rhino? My goal is to be able to take hand-drawn contours and turn them into curves.
If there’s nothing already existing I’ll put this on the to-do list once I’m comfortable with the existing tools I need to solve my problems. I could see it theoretically being possible, eg take the two traced edges and tween between them, however, I’m only halfway through the Rhino.Inside guide so I’ll finish that first.
