# ptf_circle
|
|
|
|
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](https://github.com/JustinSDK/dotSCAD/blob/master/examples/maze/noisy_circle_maze.scad).
|
|
|
|
|
|
|
|
**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)];
|
