## Class Description

     TGeoShapeAssembly - The shape encapsulating an assembly (union) of volumes.

    _____________________________________________________________________________

TGeoShapeAssembly()

     Default constructor

TGeoShapeAssembly(TGeoVolumeAssembly *vol)

     Constructor specifying hyperboloid parameters.

~TGeoShapeAssembly()

     destructor

void ComputeBBox()

     Compute bounding box of the assembly

void ComputeNormal(Double_t *point, Double_t *dir, Double_t *norm)

     Compute normal to closest surface from POINT. Should not be called.

Bool_t Contains(Double_t *point) const

     Test if point is inside the assembly

Int_t DistancetoPrimitive(Int_t /*px*/, Int_t /*py*/)

     compute closest distance from point px,py to each vertex. Should not be called.

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

     Compute distance from inside point to surface of the hyperboloid.

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

     compute distance from outside point to surface of the hyperboloid.

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

     Cannot divide assemblies.

TGeoShape* GetMakeRuntimeShape(TGeoShape * /*mother*/, TGeoMatrix * /*mat*/) const

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

void InspectShape() const

     print shape parameters

void SetSegsAndPols(TBuffer3D & /*buff*/) const

     Fill TBuffer3D structure for segments and polygons.

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 SavePrimitive(ofstream & /*out*/, Option_t * /*option*/)

     Save a primitive as a C++ statement(s) on output stream "out".

void SetPoints(Double_t * /*points*/) const

     No mesh for assemblies.

void SetPoints(Float_t * /*points*/) const

     No mesh for assemblies.
