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.

is_outside() [3/4]

bool wmtk::components::topological_offset::UnionEnvelope::is_outside ( const std::array< Eigen::Vector2d, 2 > &  edge ) const

inlineoverridevirtual

The 2D pair is VIRTUAL where the 3D edge query is not, so a containment-only composite over several envelopes can answer them. wmtk::Envelope declares virtual is_outside only for the 3D triangle and the 3D point – which is all a 3D composite needs – and 2D's containment path asks these two instead. See the composites in components/topological_offset/.../TagEnvelopes.hpp, and the invariant stated there: a composite must never reach the NON-virtual queries below, whose BVH it does not have.

Reimplemented from wmtk::SampleEnvelope.

bool wmtk::components::topological_offset::UnionEnvelope::is_outside ( const std::array< Eigen::Vector3d, 3 > &  tris ) const
