# 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>;

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

pts = [for(p = points) [p.x, p.y, rands(100, 150, 1)[0]]];
pts2 = [for(p = pts) [p.x, p.y, p.z - 100]];

sf_solidifyT(pts, pts2, triangles = triangles);
``````

``````use <triangle/tri_delaunay.scad>;

thickness = .2;
a_step = 15;
r_step = 0.2;
scale = 100;

function f(x, y) = (y ^ 2 - x ^ 2) / 4;

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

points1 = [for(p = pts2d) scale * [p.x, p.y, f(p.x, p.y)]];
points2 = [for(p = points1) [p.x, p.y, p.z - scale * thickness]];
triangles = tri_delaunay(pts2d);

sf_solidifyT(points1, points2, triangles);
