	The 2D counterpart, for Edges2d: the same tree, which holds the 2D input lifted to z = 0.
double	primitive_distance (int64_t id, const Eigen::Vector3d &p, Eigen::Vector3d *grad=nullptr, Eigen::Matrix3d *hess=nullptr) const
	The distance d from p to primitive id alone, with its gradient and Hessian when asked for (nullptr = not wanted).

double	primitive_triangle_distance (int64_t id, const std::array< Eigen::Vector3d, 3 > &tri) const
	The distance between the triangle tri and primitive id alone.
double	primitive_segment_distance (int64_t id, const std::array< Eigen::Vector2d, 2 > &seg) const
	The 2D counterpart, for Edges2d: the distance between the segment seg and primitive id alone – a 2D front edge where the 3D query takes a front face.

Detailed Description

Inside means inside any member: the tube union. Assigned to the inherited m_envelope, so the shared engine's "may this surface vertex land on a non-surface position" point check keeps its semantics with no changes there.

Four containment queries are VIRTUAL – the 3D triangle, the 3D point, the 2D segment and the 2D point – so a containment-only composite over several envelopes can answer them. They are exactly what the 3D and the 2D containment paths ask. The 3D segment query is not virtual. See the composites in wmtk/envelope/CompositeEnvelopes.hpp, and the invariant stated there: a composite must never reach the NON-virtual queries, whose BVH it does not have.

Reimplemented from wmtk::Envelope.
