Constructor & Destructor Documentation

Arb8() [1/4]

Geant4GM::Arb8::Arb8	(	const std::string &	name,
		double	hz,
		std::vector< VGM::TwoVector >	vertices )

Standard constructor to define Arb8 from parameters

Parameters

hz	half-length along the z axis in mm
vertices	vector of (x,y) coordinates of vertices first four points are the (x,y) coordinates of the vertices sitting on the -dz plane; last four points are the (x,y) coordinates of the vertices sitting on the +dz plane;

The order of defining the vertices of an arb8 is the following:

• point 0 is connected with points 1,3,4
• point 1 is connected with points 0,2,5
• point 2 is connected with points 1,3,6
• point 3 is connected with points 0,2,7
• point 4 is connected with points 0,5,7
• point 5 is connected with points 1,4,6
• point 6 is connected with points 2,5,7
• point 7 is connected with points 3,4,6

Points can be identical in order to create shapes with less than vertices.

Member Function Documentation

IsTwisted()

bool Geant4GM::Arb8::IsTwisted ( std::vector< VGM::TwoVector > vertices )

static

From TgeoArb8. Computes tangents of twist angles (angles between projections on XY plane of corresponding -dz +dz edges).

Definition at line 81 of file Arb8.cxx.

MaxTwistAngle()

double Geant4GM::Arb8::MaxTwistAngle ( const std::vector< VGM::TwoVector > & vertices )

static

Returns the largest twist of the four lateral faces, in degrees. This is the quantity G4GenericTrap limits to 90 degrees, so it says whether a twisted Arb8 can be converted to Geant4 at all.

Definition at line 65 of file Arb8.cxx.

Name()

std::string Geant4GM::Arb8::Name ( ) const

virtual

Return the name of this solid.

Implements VGM::IArb8.

Definition at line 433 of file Arb8.cxx.

NofVertices()

int Geant4GM::Arb8::NofVertices ( ) const

virtual

Return the number of vertices.

Implements VGM::IArb8.

Definition at line 439 of file Arb8.cxx.

Vertex()

VGM::TwoVector Geant4GM::Arb8::Vertex ( int index ) const

virtual

Return the index-th vertex.

Implements VGM::IArb8.

Definition at line 442 of file Arb8.cxx.

TwistAngle()

double Geant4GM::Arb8::TwistAngle ( int index ) const

virtual

Return the index-th twist angle.

Implements VGM::IArb8.

Definition at line 454 of file Arb8.cxx.

ZHalfLength()

double Geant4GM::Arb8::ZHalfLength ( ) const

virtual

Return the half-length along the z axis in mm.

Implements VGM::IArb8.
