void	conservativeBounds (Vec3 &lower, Vec3 &upper) const override
	Accumulate a conservative axis-aligned bounding box of the trimmed patch.

bool	containsPointOnSurface (const Vec3 &) const override
	True if the 3D point lies on the trimmed patch within tolerance.

void	appendIntersections (const Vec3 &, const Vec3 &, double, double, std::vector< RayHit > &) const override
	Append every hit of the ray with the trimmed patch in [minDistance, maxDistance], with the outward normal; no tangential grazes.

double	distanceSqToPatch (const Vec3 &point) const override
	Squared distance from a 3D point to the trimmed patch (used for Safety).

Vec3	normalAt (const Vec3 &) const override
	Outward-oriented normal at (or nearest to) the given point.

void	parametricMetric (const Vec2 &, double &gUU, double &gUV, double &gVV) const override
	A triangle carries no parametric domain, so the form is the identity.

double	capacityContribution () const override
	Signed divergence-theorem contribution to the enclosed volume.

bool	capacityIsExact () const override
	Whether capacityContribution() is analytically exact for this surface.

void	appendDisplayMesh (std::vector< Vec3 > &vertices, std::vector< std::array< int, 3 > > &triangles) const override
	Append this patch's visualization triangulation (navigation must never depend on it).

void	appendDirectedEdges (std::vector< std::pair< Vec3, Vec3 > > &edges) const override
	Append the 3D directed boundary edges of the patch, for solid-closure validation.
