Class Description

 TGeoEltu - elliptical tube class. It takes 3 parameters : 
 semi-axis of the ellipse along x, semi-asix of the ellipse along y
 and half-length dz. 

/* */
 Dummy constructor
TGeoEltu(Double_t a, Double_t b, Double_t dz)
 Default constructor specifying X and Y semiaxis length
TGeoEltu(const char *name, Double_t a, Double_t b, Double_t 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
Double_t Capacity()
 Computes capacity of the shape in [length^3]
void ComputeBBox()
 compute bounding box of the tube
void ComputeNormal(Double_t *point, Double_t *dir, Double_t *norm)
 Compute normal to closest surface from POINT.
Bool_t Contains(Double_t *point)
 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 DistFromInside(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe)
 compute distance from inside point to surface of the tube
Double_t DistFromOutside(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe)
 compute distance from outside point to surface of the tube and safe distance
TGeoVolume * Divide(TGeoVolume * /*voldiv*/, const char * /*divname*/, Int_t /*iaxis*/, Int_t /*ndiv*/, Double_t /*start*/, Double_t /*step*/)
 Divide the shape along one axis.
void GetBoundingCylinder(Double_t *param)
--- Fill vector param[4] with the bounding cylinder parameters. The order
 is the following : Rmin, Rmax, Phi1, Phi2
TGeoShape * GetMakeRuntimeShape(TGeoShape *mother, TGeoMatrix * /*mat*/)
 in case shape has some negative parameters, these has to be computed
 in order to fit the mother
void InspectShape()
 print shape parameters
Double_t Safety(Double_t *point, Bool_t in)
 computes the closest distance from given point to this shape, according
 to option. The matching point on the shape is stored in spoint.
void SavePrimitive(ostream &out, Option_t * /*option*/ /*= ""*/)
 Save a primitive as a C++ statement(s) on output stream "out".
void SetEltuDimensions(Double_t a, Double_t b, Double_t dz)
 Set dimensions of the eliptical tube.
void SetDimensions(Double_t *param)
 Set shape dimensions starting from an array.
void SetPoints(Double_t *points)
 Create eliptical tube mesh points
Int_t GetNmeshVertices()
 Returns the number of vertices on the mesh.
void SetPoints(Float_t *points)
 Create eliptical tube mesh points
const TBuffer3D & GetBuffer3D(Int_t reqSections, Bool_t localFrame)
 Fills a static 3D buffer and returns a reference.
Double_t GetA()
{return fRmin;}
Double_t GetB()
{return fRmax;}
Bool_t IsCylType()
{return kTRUE;}
