Member Function Documentation

static std::pair<FaceVector, FaceVector> Acts::detail::FacesHelper::convexFaceMesh ( const std::vector< Vector3D > &  vertices,
bool  centerLast = false 
)
inlinestatic

This method words for all convex type surface setups It includes:

Rectangle / Triangle / Polygon Full disc, ellipse, half ring

Parameters
verticesThe vector of vertices
centerLastBoolean indicator if the center is given for a better triangulation method as last element of the vector

Triangular mesh construction

static std::pair<FaceVector, FaceVector> Acts::detail::FacesHelper::cylindricalFaceMesh ( const std::vector< Vector3D > &  vertices,
bool  fullTwoPi = true 
)
inlinestatic

This method works for all concentric type surface setups It includes :

  • Cylinder (concentric bows on each side, separated by z)
  • Cut-off cone

The single requirement is that the #vertices are equal and the input vector is splittable in half into the two bows.

Parameters
verticesThe vector of vertices
fullTwoPiThe indicator if the concentric face is closed
