I am new to Rhino and I face a related problem and I need help from whoever is available: I am working on a 3D animal head construction project from stainless wire using Rhino 6 + Matlab, whose data is transferred to a wire bender homemade controlled by Arduino + [Processing].
This is the sequence: extract curves from the 3D object → export the xyz coordinates of each one by the script “ExporPointsToExcel” by Dale Fugier →
send xyz to Matlab that converts them to LRA (length, radius, angle) → from Matlab, send to Processing as .txt, which interprets, generates the respective image for viewing and sends the data to Arduino to move the machine axes.
The big headache is that the images displayed in Processing are different from those of Rhino, that is, the manufactured part will not be the same as the drawing; I need clarification to understand what I’m doing wrong, so I ask: IS THERE A CORRECT OBJECT POSITION FOR THE EXTRACTION OF COORDINATES IN THE RHINO?
Otherwise, I’m sure the error will be in Processing
I did several tests changing positions randomly in Rhino and I confess that I worked hard to match objects (Rhino - Processing), as I show in video 2
That’s how I’ve been doing it to get the right image.
In the first video, notice the difference between the two objects; note that in the second video, after many changes in positions in Rhino, the objects were matched.
Ah yes! remembering that in the 1st example I made the separation between two points so as not to duplicate.
