Data Members

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

 Default constructor specifying X and Y semiaxis length

 Default constructor specifying X and Y semiaxis length

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

 destructor

 compute bounding box of the tube

 Compute normal to closest surface from POINT.

 test if point is inside the elliptical tube

 compute closest distance from point px,py to each vertex

 compute distance from inside point to surface of the tube

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

--- Fill vector param[4] with the bounding cylinder parameters. The order
 is the following : Rmin, Rmax, Phi1, Phi2

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

 print shape parameters

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

 create tube mesh points

 create tube mesh points
