Class Description

TGeoCompositeShape() :TGeoBBox(0, 0, 0)

 Default constructor

TGeoCompositeShape(const char *name, const char *expression) :TGeoBBox(0, 0, 0)

 Default constructor

TGeoCompositeShape(const char *expression) :TGeoBBox(0, 0, 0)

 Default constructor

~TGeoCompositeShape()

 destructor

void ComputeBBox()

 compute bounding box of the sphere

Bool_t Contains(Double_t *point) const

 test if point is inside this sphere

Double_t DistToIn(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe) const

 Compute distance from outside point to this composite shape.

Double_t DistToOut(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe) const

 Compute distance from inside point to outside of this composite shape.

Double_t DistToSurf(Double_t * /*point*/, Double_t * /*dir*/) const

 computes the distance to next surface of the sphere along a ray
 starting from given point to the given direction.

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

 Divide all range of iaxis in range/step cells

void InspectShape() const

 print shape parameters

void MakeNode(const char *expression)

 Make a booleann node according to the top level boolean operation of expression.
 Propagates signal to branches until expression is fully decomposed.

void NextCrossing(TGeoParamCurve * /*c*/, Double_t * /*point*/) const

 computes next intersection point of curve c with this shape

void Paint(Option_t *option)

 paint this shape according to option

void PaintNext(TGeoHMatrix *glmat, Option_t *option)

 paint this shape according to option

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 SetPoints(Double_t *buff) const

 create points for a composite shape

void SetPoints(Float_t *buff) const

 create points for a composite shape

void Sizeof3D() const

 compute size of this 3D object
