update()

template<typename LatticeT , typename CellT >

template<typename PositionT >

bool MayaFlux::Kinesis::SymbolicTrajectory< LatticeT, CellT >::update ( const PositionT &  position )

inline

Observe one new position, updating the cell sequence.

Template Parameters

PositionT

glm::vec2 for a Lattice2D-backed trajectory, glm::vec3 for a Lattice3D-backed trajectory; must match what LatticeT::cell_at accepts

Parameters

position

Position in the same coordinate space as the lattice

Returns

true if this observation crossed into a different cell than the previous observation, false if it stayed in the same cell or this is the first observation
