The figure is built by the following code. Its data comes from the functions on the data helpers page.
use ironlab::prelude::*;
use crate::fields::*;
pub const TITLE: &str = "Surface";
pub const DESCRIPTION: &str = "The Julia field drawn as a surface whose faces are coloured by height and outlined \
with thin black edges. In the viewer, drag in rotate mode to change the azimuth and elevation of the view.";
pub fn figure() -> Figure {
let (x, y, z) = julia_grid(41);
let mut fig = Figure::new()
.size_mm(160.0, 100.0)
.title(r"Surface of $\ln(1 + |z_3|)$");
let mut ax = fig.axes3(0, 0);
ax.surf(&x, &y, &z).edge_width(0.25);
ax.xlabel("$x$")
.ylabel("$y$")
