Function simplicity::in_sphere [−][src]
pub fn in_sphere<T: ?Sized, Idx: Ord + Copy>(
list: &T,
index_fn: impl Fn(&T, Idx) -> Vector3<f64> + Clone,
i: Idx,
j: Idx,
k: Idx,
l: Idx,
m: Idx
) -> bool
Returns whether the last point is inside the sphere that goes through the first 4 points after perturbing them.
Takes a list of all the points in consideration, an indexing function, and 5 indexes to the points to calculate the in-sphere of.
Example
let points = vec![ Vector3::new(0.0, 0.0, 0.0), Vector3::new(4.0, 0.0, 0.0), Vector3::new(0.0, 4.0, 0.0), Vector3::new(0.0, 0.0, 4.0), Vector3::new(1.0, 1.0, 1.0), ]; let inside = in_sphere(&points, |l, i| l[i], 0, 2, 1, 3, 4); assert!(inside); let inside = in_sphere(&points, |l, i| l[i], 2, 3, 1, 4, 0); assert!(!inside);
