Template Struct NavigationOptions

Struct Documentation

template<typename object_t>
struct Acts::NavigationOptions

struct for the Navigation options that are forwarded to the geometry

Template Parameters

  • propagator_state_t: Type of the object for navigation state

  • object_t: Type of the object for navigation to check against

Public Functions

NavigationOptions(NavigationDirection ndir, BoundaryCheck bcheck, bool resolves = true, bool resolvem = true, bool resolvep = false, const object_t *sobject = nullptr, const object_t *eobject = nullptr)

Constructor.

Parameters

  • nDir: Navigation direction prescription

  • bcheck: Boundary check for the navigation action

  • sobject: Start object to check against

  • eobject: End object to check against

  • maxStepLength: Maximal step length to check against

Public Members

BoundaryCheck boundaryCheck = true

The boundary check directive.

const object_t *endObject = nullptr

object to check against: at end

std::vector<GeometryIdentifier> externalSurfaces = {}

External surface identifier for which the boundary check is ignored.

NavigationDirection navDir = forward

The navigation direction.

double overstepLimit = -1_um

The overstep tolerance for this navigation step.

Note

must be negative as it describes overstepping

double pathLimit = std::numeric_limits<double>::max()

The maximum path limit for this navigation step.

bool resolveMaterial = true

Always look for material.

bool resolvePassive = false

always look for passive

bool resolveSensitive = true

Always look for sensitive.

const object_t *startObject = nullptr

object to check against: at start

const Surface *targetSurface = nullptr

Target surface to exclude.
