Tree Barks
I have been working on a series of automated drawings based on a small program I wrote. The application translates pixel values of an image into lines in four directions (horizontal, vertical, bottom-left/top-right, top-left/bottom-right). By overlapping these lines, various shades of grey are created, thus translating the bitmap image into a line drawing. The resulting .svg vector file is plotted out with archival ink on 14 by 17-inch paper (Strathmore, 80 lb.) The drawing process takes, depending on the complexity of the image, 3 to 4 hours.
I did a series of drawings based on patterns found in nature, in this case, the pattern of various tree barks.
