Class Description

 TUBE is a tube. It has 6 parameters:

     - name       name of the shape
     - title      shape's title
     - material  (see TMaterial)
     - rmin       inside radius
     - rmax       outside radius
     - dz         half length in z

TTUBE()

 TUBE shape default constructor

TTUBE(const char *name, const char *title, const char *material, Float_t rmin, Float_t rmax, Float_t dz,Float_t aspect) : TShape(name, title,material)

 TUBE shape normal constructor

TTUBE(const char *name, const char *title, const char *material, Float_t rmax, Float_t dz) : TShape(name, title,material)

 TUBE shape "simplified" constructor

void MakeTableOfCoSin() const // Internal cache - const so other const fn can use

~TTUBE()

 TUBE shape default destructor

Int_t DistancetoPrimitive(Int_t px, Int_t py)

 Compute distance from point px,py to a TUBE

 Compute the closest distance of approach from point px,py to each
 computed outline point of the TUBE.

void SetNumberOfDivisions (Int_t ndiv)

 Set number of divisions used to draw this tube

void SetPoints(Double_t *points) const

 Create TUBE points

void SetSegsAndPols(TBuffer3D & buffer) const

void Sizeof3D() const

 Return total X3D needed by TNode::ls (when called with option "x")

void Streamer(TBuffer &R__b)

 Stream an object of class TTUBE.

const TBuffer3D& GetBuffer3D(Int_t reqSections) const
