Construction process
This file was derived from a 3D model of DNA, converted to SVG and coloured using David Eccles' STL2SVG script:
type=orig; ~/scripts/stl2svg.pl ./DNA_linear_complete_helix1.stl:330 ./DNA_linear_complete_helix2.stl:200 ./DNA_linear_complete_${type}_A.stl:140 ./DNA_linear_complete_${type}_C.stl:250 ./DNA_linear_complete_${type}_G.stl:90 ./DNA_linear_complete_${type}_T.stl:30 > out_${type}.svg type=mut; ~/scripts/stl2svg.pl ./DNA_linear_complete_helix1.stl:330 ./DNA_linear_complete_helix2.stl:200 ./DNA_linear_complete_${type}_A.stl:140 ./DNA_linear_complete_${type}_C.stl:250 ./DNA_linear_complete_${type}_G.stl:90 ./DNA_linear_complete_${type}_T.stl:30 > out_${type}.svg
The DNA models were then combined and annotated using Inkscape. The DNA backbone for the model is a pentagon extruded over a sine wave using David Eccles' guided path extrude script. The model source file (in OpenSCAD format) is shown below:
