Geodesic dome, radius 30.00 mm, frequency 10

Brief instruction

I run OpenSCAD 2016.03.10.nightly in Devuan Linux. I recommend OpenSCAD 2015.03.

OpenSCAD 2015 introduced font handling function text(). I used it to generate 3D numbers in letter_vertex() module as you see.

module letter_vertex(s1=5, letter, p, p_offset=5, c1="black")
{
x = abs_add(p[0], p_offset);
y = abs_add(p[1], p_offset);
z = abs_add(p[2], p_offset);
translate([x, y, z]) color(c1) rotate([90, 0, 45])
linear_extrude(height=0.5, center = true, convexity = 10, twist = 0)
text(letter, size=s1, font="Courier");
}

build_dome_parts.scad is main program. Other scad files are dome data files.
pydome_sorted.scad is for the freqency 10 dome.

include ;

To create a frequency 2 dome, put dome_r30_f2_v38.scad in the <> and press F5.
It will generate a simple dome.

include ;

Naming convention of dome data file

r30 is radius 30.00
f2 is frequency 2
v38 is numbe of vertices is 38.
dome_r30_f2_v38.scad

I've been porting Geodome by Edward A. Falk, 2005 to Python 3.x and OpenSCAD.
It is a sample dome generated by pydome. OpenSCAD handles 3D graphic side to produce dome parts.
