/* */

TGeoCylVoxels()

     Default constructor

TGeoCylVoxels(TGeoVolume *vol) :TGeoVoxelFinder(vol)

     Constructor

~TGeoCylVoxels()

     Destructor

void BuildVoxelLimits()

    --- Compute boundary limits in R, Phi and Z coordinates for all daughters
     of fVolume

Double_t Efficiency()

    --- Compute voxelization efficiency.

void FindOverlaps(Int_t inode) const

     create the list of nodes for which the bboxes overlap with inode's bbox

Int_t* GetCheckList(Double_t *point, Int_t &nelem)

    --- Get the list of nodes possibly containing a given point.
     convert the point to cylindrical coordinates

Int_t* GetNextVoxel(Double_t * /*point*/, Double_t * /*dir*/, Int_t & /*ncheck*/)

    --- Get the list of nodes possibly crossed by a given ray.

Int_t IntersectIntervals(Double_t vox1, Double_t vox2, Double_t phi1, Double_t phi2) const

     Intersect a phi voxel interval in range (0,360) with a node phi interval of
     extended range. Returns 0 if no intersection, 1 if they do intersect and
     2 if they are identical.

void Print(Option_t *) const

     Print info about voxels.

void SortAll(Option_t *)

     Order voxels along R, Phi, Z.
       printf("Sorting voxels for %sn", fVolume->GetName());

void Voxelize(Option_t *)

    --- Voxelize fVolume.
       printf("Voxelizing %sn", fVolume->GetName());
