Detailed Description

Bounds for a cylindrical Volume, the decomposeToSurfaces method creates a vector of up to 6 surfaces:

case A) 3 Surfaces (full cylindrical tube): BoundarySurfaceFace [index]:

• negativeFaceXY [0] : Trk::DiscSurface with $r_{inner}=0$, parallel to $xy$ plane at negative $z$
• positiveFaceXY [1] : Trk::DiscSurface with $r_{inner}=0$, parallel to $xy$ plane at positive $z$
• cylinderCover [2] : Trk::CylinderSurface confining the Trk::Volume

case B) 4 Surfaces (tube with inner and outer radius): BoundarySurfaceFace [index]:

• negativeFaceXY [0] : Trk::DiscSurface with $r_{inner}>0$, parallel to $xy$ plane at negative $z$
• positiveFaceXY [1] : Trk::DiscSurface with $r_{inner}>0$, parallel to $xy$ plane at positive $z$
• tubeOuterCover [2] : Trk::CylinderSurface with $r = r_{outer}$
• tubeInnerCover [3] : Trk::CylinderSurface with $r = r_{inner}$

case C) 6 Surfaces (sectoral tube with inner and outer radius): BoundarySurfaceFace [index]:

• negativeFaceXY [0] : Trk::DiscSurface with $r_{inner}>0$ and $\phi < \pi$, parallel to $xy$ plane at negative $z$
• positiveFaceXY [1] : Trk::DiscSurface with $r_{inner}>0$ and $\phi < \pi$, parallel to $xy$ plane at positive $z$
• tubeSectorOuterCover [2] : Trk::CylinderSurface with $r = r_{outer}$
• tubeSectorInnerCover [3] : Trk::CylinderSurface with $r = r_{inner}$
• tubeSectorNegativePhi [4] : Rectangular Trk::PlaneSurface attached to [0] and [1] at negative $\phi$
• tubeSectorNegativePhi [5] : Rectangular Trk::PlaneSurface attached to [0] and [1] at positive $\phi$

case D) 6 Surfaces (sectoral bevelled tube with inner and/or outer radius replaced by plane surface): BoundarySurfaceFace [index]:

• negativeFaceXY [0] : Trk::DiscSurface with $r_{inner}>0$ and $\phi < \pi$, parallel to $xy$ plane at negative $z$
• positiveFaceXY [1] : Trk::DiscSurface with $r_{inner}>0$ and $\phi < \pi$, parallel to $xy$ plane at positive $z$
• tubeSectorOuterCover [2] : Trk::CylinderSurface with $r = r_{outer}$ OR rectangular plane surface
• tubeSectorInnerCover [3] : Trk::CylinderSurface with $r = r_{inner}$ OR rectangular plane surface
• tubeSectorNegativePhi [4] : Rectangular Trk::PlaneSurface attached to [0] and [1] at negative $\phi$
• tubeSectorNegativePhi [5] : Rectangular Trk::PlaneSurface attached to [0] and [1] at positive $\phi$
