Class Description



 TGeoEltu()



 Dummy constructor


 TGeoEltu(Double_t a, Double_t b, Double_t dz)
           :TGeoTube(a, b, dz)



 Default constructor specifying X and Y semiaxis length


 TGeoEltu(Double_t *param)



 Default constructor specifying minimum and maximum radius
 param[0] =  A
 param[1] =  B
 param[2] = dz


 ~TGeoEltu()



 destructor


void ComputeBBox()



 compute bounding box of the tube


Bool_t Contains(Double_t *point) const



 test if point is inside the elliptical tube


Int_t DistancetoPrimitive(Int_t px, Int_t py)



 compute closest distance from point px,py to each vertex


Double_t DistToOut(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe) const



 compute distance from inside point to surface of the tube


Double_t DistToIn(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe) const



 compute distance from outside point to surface of the tube and safe distance


Double_t DistToSurf(Double_t *point, Double_t *dir) const



 computes the distance to next surface of the sphere along a ray
 starting from given point to the given direction.


TGeoVolume* Divide(TGeoVolume *voldiv, const char *divname, Int_t iaxis, Int_t ndiv, 
                             Double_t start, Double_t step) 




TGeoVolume* Divide(TGeoVolume *voldiv, const char *divname, Int_t iaxis, Double_t step) 



 Divide all range of iaxis in range/step cells


TGeoShape* GetMakeRuntimeShape(TGeoShape *mother) const



 in case shape has some negative parameters, these has to be computed
 in order to fit the mother


void InspectShape() const



 print shape parameters


void NextCrossing(TGeoParamCurve *c, Double_t *point) const



 computes next intersection point of curve c with this shape


Double_t Safety(Double_t *point, Double_t *spoint, Option_t *option) const



 computes the closest distance from given point to this shape, according
 to option. The matching point on the shape is stored in spoint.


void SetEltuDimensions(Double_t a, Double_t b, Double_t dz)




void SetDimensions(Double_t *param)




void SetPoints(Double_t *buff) const



 create tube mesh points


void SetPoints(Float_t *buff) const



 create tube mesh points
