## Examples
|
|
|
|
use <polyline_join.scad>

|
|
size = [10, 10];
|
|
|
|
rows = [
|
|
for(y = [0:size.y])
|
|
[for(x = [0:size.x]) [x, y]]
|
|
];
|
|
|
|
columns = [
|
|
for(x = [0:size.x])
|
|
[for(y = [0:size.y]) [x, y]]
|
|
];
|
|
|
|
for(line = rows) {
|
|
transformed = [for(p = line) ptf_circle(size, p)];
|
|
polyline_join(transformed)
|
|
sphere(.05);
|
|
}
|
|
|
|
for(line = columns) {
|
|
transformed = [for(p = line) ptf_circle(size, p)];
