Is there any possibility of copying code from mathematica to use with maxima, octave, gnuplot to create a truncated icosahedron? Looking at page here: https://mathematica.stackexchange.com/questions/118604/3d-graphic-of-soccer-ball Is there possibility to make equivalent picture with opensource tooks? Some have used geogebra and have created: https://www.geogebra.org/material/show/id/xNgwKQJK https://www.geogebra.org/material/show/id/AfNmbnDD And another person using javascript https://stackoverflow.com/questions/20789627/understanding-the-geometry-of-a-truncated-icosahedron-for-rendering Using parametric one can create a sphere using gnuplot, but how can one put the faces to be pentagons and hexagons with some filled? Thanks for any pointers and advice.
