Function orient3_scene

pub fn orient3_scene(
    count: usize,
    rate: DegeneracyRate,
    seed: u64,
) -> Vec<[DVec3; 4]>

Generate count 3D orientation queries with the given degeneracy rate.

Degenerate cases are exactly coplanar: d = a + i*(b-a) + j*(c-a) for integers i, j, so no rounding can move the point off the plane.
