ConstructiveGeometry.jl Documentation

This package provides tools for describing 3d objects in Julia. For example, this is the Julia code used to draw the logo of this page:

using ConstructiveGeometry
using CairoMakie

hexagon = polygon([[cospi(t/3),sinpi(t/3)] for t in 0:5])
c1, c2, c3 = parse.(ConstructiveGeometry.Colorant, ( "#cb3c33", "#9558b2", "#389826"))

bolt = linear_extrude(5)*(8*hexagon) ∪ cylinder(15,4) ∪
	rotate_extrude(7*360, slide=14)*translate([1,0])*square(4,1)

m = union(c1*bolt, [20,0,0]+c2*bolt, [10,17,0]+c3*bolt)

save("logo.png", Makie.plot(m))


This package defines three kinds of abstract geometric objects (in either two or three dimensions):

Any geometric object defined in this way can then be instantiated as an explicit mesh. The mesh may be visualized directly within Julia (using Makie) or exported as an STL (for 3d objects) or SVG (for 2d objects) file.
