Triangulation code ripped from ttf2mesh and ported to Rust.
use ttf2mesh_triangulation::Triangulator;
fn main() {
let mut triangulator = Triangulator::new();
triangulator
.add_contour(
0,
vec![
[-100., -100.],
[100., -100.],
[100., 100.],
[-100., 100.]
],
)
.unwrap();
triangulator
.add_contour(
0,
vec![
[-50., -50.],
[50., -50.],
[50., 50.],
[-50., 50.]
]
)
.unwrap();
let triangles: Vec<[[f32; 2]; 3]> = triangulator.triangulate().unwrap();
dbg!(triangles);
}A test included in this repo checks byte-for-byte equality with ttf2mesh. It checks 11165 glyphs from two separate fonts. The test file is 100MB so it's not included in the git repo, and must be generated. More test fonts can be added easily in test_gen/ttf2mesh_test_data_gen.c.
