ptf_y_twist

Twist a point along the y-axis. You can use it to create something such as a twisted maze.

Since: 2.3

Parameters

• size : 2 value array [x, y], rectangle with dimensions x and y.
• point : The point to be twisted.
• angle : The number of degrees.

Examples

use <polyline_join.scad>
use <ptf/ptf_y_twist.scad>

size = [10, 20];

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) {
    twisted = [for(p = line) ptf_y_twist(size, p, 90)];
    polyline_join(twisted)
	    sphere(.05);
}

for(line = columns) {
    twisted = [for(p = line) ptf_y_twist(size, p, 90)];
    polyline_join(twisted)
	    sphere(.05);
}
