# 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.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);
|
