TGeoPcon Class Reference

A polycone is represented by a sequence of tubes/cones, glued together at defined Z planes.

The polycone might have a phi segmentation, which globally applies to all the pieces. It has to be defined in two steps:

1. First call the TGeoPcon constructor to define a polycone:

TGeoPcon()
dummy ctor
Definition: TGeoPcon.cxx:104
• phi1: starting phi angle in degrees
• dphi: total phi range
• nz: number of Z planes defining polycone sections (minimum 2)
2. Define one by one all sections [0, nz-1]
Double_t rmin, Double_t rmax);
virtual void DefineSection(Int_t snum, Double_t z, Double_t rmin, Double_t rmax)
Defines z position of a section plane, rmin and rmax at this z.
Definition: TGeoPcon.cxx:615
• i: section index [0, nz-1]
• z: z coordinate of the section
• rmin: minimum radius corresponding too this section
• rmax: maximum radius.

The first section (i=0) has to be positioned always the lowest Z coordinate. It defines the radii of the first cone/tube segment at its lower Z. The next section defines the end-cap of the first segment, but it can represent also the beginning of the next one. Any discontinuity in the radius has to be represented by a section defined at the same Z coordinate as the previous one. The Z coordinates of all sections must be sorted in increasing order. Any radius or Z coordinate of a given plane have corresponding getters:

Double_t * GetRmax() const
Definition: TGeoPcon.h:81
Double_t * GetZ() const
Definition: TGeoPcon.h:83
Double_t * GetRmin() const
Definition: TGeoPcon.h:79

Note that the last section should be defined last, since it triggers the computation of the bounding box of the polycone.
