extract_vertex_velocities()

std::vector< glm::vec3 > MayaFlux::Nodes::Network::PhysicsOperator::extract_vertex_velocities ( ) const

overridevirtual

Per-particle PhysicsState::velocity, in the same global vertex-index order get_vertex_data() produces.

Reimplemented from MayaFlux::Nodes::Network::GraphicsOperator.
