Transform a point inside a rectangle to a point inside a circle. You can use it to create something such as a noisy circle maze.

Since: 2.3

Parameters

• size : 2 value array [x, y], rectangle with dimensions x and y.
• point : The point to be transformed.

Examples

use <hull_polyline3d.scad>;
use <ptf/ptf_circle.scad>;

size = [10, 10];

rows = [
    for(y = [0:size[1]])
        [for(x = [0:size[0]]) [x, y]]
];

columns = [
    for(x = [0:size[0]])
        [for(y = [0:size[1]]) [x, y]]
];

for(line = rows) {
    transformed = [for(p = line) ptf_circle(size, p)];
    hull_polyline3d(transformed, thickness = .1);
}

for(line = columns) {
    transformed = [for(p = line) ptf_circle(size, p)];
    hull_polyline3d(transformed, thickness = .1);
}
