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

vertices	The vector of vertices
centerLast	Boolean indicator if the center is given for a better triangulation method as last element of the vector

Triangular mesh construction

Here is the caller graph for this function:

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

vertices	The vector of vertices
fullTwoPi	The indicator if the concentric face is closed
