I am working on an Arduino project, via Firefly, where I want to color code someone's distance from a sensor by using Blue, Green and Red LED's that sequentially illuminate at designated distances from said sensor.  When touching the sensor, the only LED still illuminated will be the Red one.  However, I would like this relationship to change every five minutes or so, so that the color illuminated at the closest distance is not always predictably Red.   Is there a way to have a list of three…See More

Hello all! I am working on a definition that essentially needs to take a list and create a series of polylines, with the first polyline being created from the set of (0) refrenced points in each list, followed by a polyline from the (1) refrenced points, (2), (3), (4) and so on.  For example in the case below, I would like there to be 4 polylines created from the given sets of points.  How can I do this without calling out each list item, one by one, and then having x number of polyline…See More

I am new to and have been experimenting with the image samplercomponent, I would like to be able to create what should basically looklike a stippled pen and ink drawing with a sort of point densityfield.  Essentially, I would like darker colors in the sampled image toproduce a field of densely populated points whereas the lighter colorsto be less densely populated with points.   Any ideas?See More

I recently installed grasshopper and rhino on a new iMac and I amrunning windows 7 through vmware... has anyone had issues with pointsin grasshopper previewing in rhino? For example, if I divide a curve ingrasshopper, there are no previewed x's where the points should be. Thecomponent is working: if I bake the points they show up in rhino, butotherwise I can't get any working preview. See More
