# ptf_sphere
|
|
|
|
Transforms a point inside a rectangle to a point of a sphere. It can create things such as [sphere maze](https://github.com/JustinSDK/dotSCAD/blob/master/examples/maze/sphere_maze.scad).
|
|
|
|
|
|
|
|
**Since:** 2.3
|
|
|
|
## Parameters
|
|
|
|
- `size` : 2 value array `[x, y]`, rectangle with dimensions `x` and `y`.
|
|
- `point` : The point to be transformed.
|
|
- `radius` : The radius of the sphere.
|
|
- `angle` : [za, xa] mapping angles.
|
|
|
|
## Examples
|
|
|
|
use <polyline_join.scad>
|
|
use <ptf/ptf_sphere.scad>
|
|
|
|
size = [20, 10];
|
|
radius = 5;
|
|
angle = [180, 270];
|
|
|
|
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_sphere(size, p, radius, angle)];
|
|
polyline_join(transformed)
|
|
sphere(.25);
|
|
}
|
|
|
|
for(line = columns) {
|
|
transformed = [for(p = line) ptf_sphere(size, p, radius, angle)];
|
|
polyline_join(transformed)
|
|
sphere(.25);
|
|
}
