Class Description


TGeoUnion()
 Default constructor

TGeoUnion(const char *expr1, const char *expr2) :TGeoBoolNode(expr1, expr2)
 Constructor

~TGeoUnion()
 Destructor
 --- deletion of components handled by TGeoManager class.

void ComputeBBox(Double_t &dx, Double_t &dy, Double_t &dz, Double_t *origin)
 Compute bounding box corresponding to a union of two shapes.

Bool_t Contains(Double_t *point) const
 Find if a union of two shapes contains a given point

Int_t DistanceToPrimitive(Int_t px, Int_t py)
 Compute minimum distance to shape vertices

Double_t DistToOut(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe) const
 Compute distance from a given point to outside.
   printf("Point is : %g, %g, %gn", point[0], point[1], point[2]);

Double_t DistToIn(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe) const
 Compute distance from a given point to inside.

Int_t GetNpoints() const
 Returns number of vertices for the composite shape described by this union.

void SetPoints(Double_t *buff) const
 Fill buffer with shape vertices.

void SetPoints(Float_t *buff) const
 Fill buffer with shape vertices.

void Sizeof3D() const
