pub fn near_coplanar_scene(count: usize, seed: u64) -> Vec<Orient3Case> ⓘExpand description
Generate 3D orientation queries that are nearly coplanar.
Distinct from orient3_scene’s degenerate cases, which lie exactly on the
plane and are therefore answered zero. These sit one unit-in-the-last-place
off it: the filter must defer, and the exact path must then return a
non-zero sign. A suite containing only exact degeneracies cannot tell a
correct exact path from one that always answers zero.
