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 \( \phi \)
