Class Description


 Full description with examples and pictures














 TGeoCylVoxels()


 Default constructor



 TGeoCylVoxels(TGeoVolume *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)


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


 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 *)


 Print info about voxels.



void SortAll(Option_t *)


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



void Voxelize(Option_t *)


--- Voxelize fVolume.
   printf("Voxelizing %s\n", fVolume->GetName());
