Class Description

 TGeoShape - base class for all geometrical shapes. Abstract functionality
   regarding point and segment classification has to be implemented by classes
   that inherits from it.



/*

*/


~TGeoShape()
 Destructor

const char* GetName() const

Int_t ShapeDistancetoPrimitive(Int_t numpoints, Int_t px, Int_t py) const

Double_t ClosenessToCorner(Double_t *point, Bool_t in, Double_t *vertex, Double_t *normals, Double_t *cldir)
 Static method returning distance to closest point of a corner. The corner is
 defined by vertex and normals to the 3 planes (in order X, Y, Z - norm[9]).
 also return unit vector pointing to this

Double_t DistToCorner(Double_t *point, Double_t *dir, Bool_t in, Double_t *vertex, Double_t *norm, Int_t &inorm)
 Static method to compute distance along a direction from inside/outside point to a corner.
 The corner is  defined by its normals to planes n1, n2, n3, and its vertex.
 Also compute distance to closest plane belonging to corner, normal to this plane and
 normal to shape at intersection point.

Int_t GetVertexNumber(Bool_t vx, Bool_t vy, Bool_t vz)
 get visible vertex number for : box, trd1, trd2, trap, gtra, para shapes
