Class Description

 TGeoScaledShape - A shape scaled by a TGeoScale transformation

/* */
_____________________________________________________________________________

TGeoScaledShape()
 Default constructor

TGeoScaledShape(const char *name, TGeoShape *shape, TGeoScale *scale) :TGeoBBox(name,0,0,0)
 Constructor

TGeoScaledShape(TGeoShape *shape, TGeoScale *scale)
 Constructor

~TGeoScaledShape()
 destructor

Double_t Capacity() const
 Computes capacity of this shape [length^3]

void ComputeBBox()
 Compute bounding box of the scaled shape

void ComputeNormal(Double_t *point, Double_t *dir, Double_t *norm)
 Compute normal to closest surface from POINT.

Bool_t Contains(Double_t *point) const
 Test if point is inside the scaled shape

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 scaled shape.

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 scaled shape.

TGeoVolume* Divide(TGeoVolume * /*voldiv*/, const char *divname, Int_t /*iaxis*/, Int_t /*ndiv*/, Double_t /*start*/, Double_t /*step*/)
 Cannot divide assemblies.

const TBuffer3D& GetBuffer3D(Int_t reqSections, Bool_t localFrame) const
 Fills a static 3D buffer and returns a reference.

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

TBuffer3D* MakeBuffer3D() const
 Creates a TBuffer3D describing *this* shape.
 Coordinates are in local reference frame.

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
 Mesh points for scaled shapes.

void SetPoints(Float_t *points) const
 Mesh points for scaled shapes.
