polyline3d

Creates a polyline from a list of [x, y, z] coordinates. It depends on the line3d module so you have to include line3d.scad.

Parameters

• points : The list of [x, y, z] points of the polyline. : A vector of 3 element vectors. The points are indexed from 0 to n-1.
• thickness : The line thickness.
• startingStyle : The end-cap style of the starting point. The value must be CAP_BUTT, CAP_CIRCLE or CAP_SPHERE (defined in line3d.scad). The default value is CAP_CIRCLE.
• endingStyle : The end-cap style of the ending point. The value must be CAP_BUTT, CAP_CIRCLE or CAP_SPHERE (defined in line3d.scad). The default value is CAP_CIRCLE.
• fn : It controlls the $fn value used by the circle and sphere module. The default value is 24.

Examples

polyline3d(
    points = [
        [1, 2, 1], 
        [-5, -4, 2], 
        [-5, 3, 3], 
        [5, 5, 4]
    ], 
    thickness = 1
);

polyline3d(
    points = [
        [1, 2, 1], 
        [-5, -4, 2], 
        [-5, 3, 3], 
        [5, 5, 4]
    ], 
    thickness = 1,
    endingStyle = CAP_SPHERE
);

polyline3d(
    points = [
        [1, 2, 1], 
        [-5, -4, 2], 
        [-5, 3, 3], 
        [5, 5, 4]
    ], 
    thickness = 1,
    startingStyle = CAP_SPHERE,
    endingStyle = CAP_SPHERE

    for(a = [0:fa:360 * circles]) 
        [r * cos(a), r * sin(a), h / (360 / fa) * (a / fa)]
