Detailed Description

Optical surface physics data for a track.

Tracks maintain a position while traversing the interstitial materials of an optical surface. This class provides transformations from this position based on the surface orientation (pre/post volume when the crossing began) and traversal direction (current state) to access relevant material and interface data in storage.

See SurfacePhysicsView, SurfaceTraversalView .

Member Function Documentation

global_normal()

Real3 celeritas::optical::SurfacePhysicsTrackView::global_normal ( ) const

inline

Get global surface normal.

The global surface normal is the normal defined by the geometry and does not include any roughness effects. By convention it points from the post-volume into the pre-volume.

is_crossing_boundary()

bool celeritas::optical::SurfacePhysicsTrackView::is_crossing_boundary ( ) const

inline

Whether the track is undergoing boundary crossing.

Returns true if there's a valid surface ID, otherwise false.

reset()

void celeritas::optical::SurfacePhysicsTrackView::reset ( )

inline

Reset the state of a track.

Invalidates the surface ID, indicating the track is no longer undergoing boundary crossing.
