# Matlab: Create Mesh or Surface From Line Plot

This is a continuation of Matlab: Lorentz Attractor, however, these methods can be applied to any line plot or collection of points.

A slightly more aesthetically pleasing representation of the Lorentz Attractor can be achieved by adding `axis off`

. And altering the view’s azimuth and elevation: `view(15, 48)`

.

Now we’re talking. Let’s say I want to make a surface or mesh from this dandy line plot. Using `surf`

or `mesh`

will throw an error, since x, y, and z are all 1D vectors! Whatever shall we do!

Never fear, mathematicians will save the day.

Delaunay created a sweet method of triangulating points. If we treat this line plot as a collection of points, we can triangulate to find an approximate surface.

```
tri = delaunay(x,y);
plot(x,y,'.')
%determine amount of triangles
[r,c] = size(tri);
disp(r)
%plot with trisurf
h = trimesh(tri, x, y, z, 'FaceAlpha', 0.6);
alpha = 0.4
view(15, 48)
axis vis3d
axis off
l = light('Position',[-50 -15 29])
lighting phong
shading interp
```

What if we’d like a surface instead of the mesh? Then we’ll change `trimesh`

to `trisurf`

add transparency (`alpha = 0.7`

) and find:
