is it possible to pull a JPG into GH as an input, and read pixel values, or convert pixels into points?
i made the following image by building a heightfield surface in rhino, extracting the points, then bringing the points into GH and scaling a circle in the xy plane based on the z location. http://farm4.static.flickr.com/3663/3320021525_bac5f9b526.jpg it would be nice to be able to get a jpg directly into grasshopper and eliminate the step of generating the heightfield surface and extrcting the points. can this be done with a VB script component, with the ability to change the # of UV sample points?
