4th order Sierpinski curve

thingiverse

This is a 4th order Sierpi?ski curve projected into three-dimensional space along its vertical axis.http://en.wikipedia.org/wiki/Sierpi%C5%84ski_curve\n\n \n \n Instructions\nI modified an original BASIC program from the July edition of Creative Computing magazine to operate within Chipmunk Basic on my Mac.\nI adjusted the code to save a text file containing the coordinates for each line segment's endpoints.\nNext, I created a blank SVG file using Inkscape. I then opened the SVG in Sublime Text and designed a polygon based on the coordinates produced by my program.\nSubsequently, I loaded the SVG into Inkscape and exported it as an Open SCAD file. From there, I exported it as an STL file.\nThe original BASIC source code is available at: https://archive.org/details/creativecomputing-1984-07\nBASIC source code and elementary documentation are included.
