Text

For more information about using fonts, refer to the chapter in the Luxor documentation.

Thebes provides a text3D() function that draws text in a 3D environment.

You specify the location of the text, and optionally supply rotation (a tuple of three angles for x, y, and z) and text alignment. By default the text in Thebes (as in Luxor) runs along the x-axis, and it lies in the x plane.

text3D("the x-axis", Point3D(50, 0, 0))
text3D("the y-axis", Point3D(0, 50, 0), rotation=(0, 0, π/2))
text3D("the z-axis", Point3D(0, 0, 0), rotation=(0, π/2, 0), halign=:right)

You can also use some of Luxor's tools for text placement, such as textextents(), which helps you get the (2D) dimensions of text.

    for x in -1200:te[4]:1200
            sethue(HSB(mod(x*y, 360), .8, .8))
            text3D("Julia", Point3D(x, y, 0), rotation=(0, 0, π/2))
    end
end
