Transforms a point inside a rectangle to a point of an arc.

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 arc.
• angle : The central angle of the arc.

Examples

use <voxel/vx_ascii.scad>;
use <ptf/ptf_bend.scad>;

t = "dotSCAD";
size = [len(t) * 8, 8];
radius = 20;
angle = 180;

for(i = [0:len(t) - 1]) {
    for(pt = vx_ascii(t[i], invert = true)) {
        bended = ptf_bend(size, pt + [i * 8, 0], radius, angle);
        translate(bended)
            sphere(0.5, $fn = 24);
    }
}
