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.

_____________________________________________________________________________
/* */

TGeoEltu()
 Dummy constructor

TGeoEltu(Double_t a, Double_t b, Double_t dz) :TGeoTube()
 Default constructor specifying X and Y semiaxis length

TGeoEltu(const char *name, Double_t a, Double_t b, Double_t dz) :TGeoTube()
 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

void ComputeNormal(Double_t *point, Double_t *dir, Double_t *norm)
 Compute normal to closest surface from POINT.

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 DistFromInside(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 DistFromOutside(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

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

void GetBoundingCylinder(Double_t *param) const
--- Fill vector param[4] with the bounding cylinder parameters. The order
 is the following : Rmin, Rmax, Phi1, Phi2

TGeoShape* GetMakeRuntimeShape(TGeoShape *mother, TGeoMatrix * /*mat*/) 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

Double_t Safety(Double_t *point, Bool_t in) 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 SavePrimitive(ofstream &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)

void SetDimensions(Double_t *param)

void SetPoints(Double_t *points) const
 create tube mesh points

Int_t GetNmeshVertices() const

void SetPoints(Float_t *points) const
 create tube mesh points

const TBuffer3D& GetBuffer3D(Int_t reqSections, Bool_t localFrame) const
