Description

The mesh primitive in StructureSynth is not very well documented bu if you spend a bit of time you can see that it is quite useful. The object and the colouring was generated in StructureSynth using 6 lines of code: >2 * {fy fz z 85} GG >rule GG md 8{ > mesh > {z -6 s 1.8 1.00001 1.00001 h -60}GG > {z -6 y 8 s 1.7 1 1 h -30}GG > {z -6 y -8 s 1.7 1 1 h 30}GG >}
