std::tuple<VariantCovariance, VariantTransportJacobian> Acts::transportCovarianceToBound(const GeometryContext &gctx, const Surface &surface, const FreeVector &parameters, CovarianceCache &cCache)

Transport the covariance to a new (surface) bound definition.

Return

a variant transport jacobian

Parameters
  • gctx: [in] The current geometry context

  • surface: [in] The surface of the bound representation

  • freeParameters: [in] The free parametrisation on the surface

  • cCache: [in,out] the covariance cache (to be modified)
