sf_solidifyT

It solidifies two surfaces with triangular mesh.

Since: 3.1

Parameters

• points1 : A list of [x, y, z]s.
• points2 : A list of [x, y, z]s.
• triangles : Determine which points are connected by an edge. All triangles have points in the same direction, counter-clockwise. See examples below.

Examples

use <triangle/tri_delaunay.scad>;
use <surface/sf_solidifyT.scad>;

points = [for(i = [0:50]) rands(-300, 300, 2)]; 
triangles = tri_delaunay(points);

pts = [for(p = points) [p[0], p[1], rands(100, 150, 1)[0]]];
pts2 = [for(p = pts) [p[0], p[1], p[2] - 100]];

sf_solidifyT(pts, pts2, triangles = triangles);	

use <triangle/tri_delaunay.scad>;
use <surface/sf_solidifyT.scad>;

thickness = .2;
a_step = 10;
r_step = 0.2;
scale = 100;

function f(x, y) = (pow(y,2)/pow(2, 2))-(pow(x,2)/pow(2, 2));

pts2d = [
    for(a = [a_step:a_step:360])
        for(r = [r_step:r_step:2])
        let(
            x = round(r * cos(a) * 100) / 100, 
            y = round(r * sin(a) * 100) / 100
        )
        [x, y] 
];

points1 = [for(p = pts2d) scale * [p[0], p[1], f(p[0], p[1])]];
points2 = [for(p = points1) [p[0], p[1], p[2] - scale * thickness]];
triangles = tri_delaunay(pts2d);
