Member Function Documentation

◆ distance()

virtual double dd4hep::rec::ISurface::distance ( const Vector3D & point ) const

pure virtual

Distance to surface

Implemented in dd4hep::rec::Surface, dd4hep::rec::VolConeImpl, dd4hep::rec::VolCylinderImpl, dd4hep::rec::VolPlaneImpl, dd4hep::rec::VolSurface, and dd4hep::rec::VolSurfaceBase.

◆ globalToLocal()

virtual Vector2D dd4hep::rec::ISurface::globalToLocal ( const Vector3D & point ) const

pure virtual

Convert the global position to the local position (u,v) on the surface

Implemented in dd4hep::rec::CylinderSurface, dd4hep::rec::Surface, dd4hep::rec::VolConeImpl, dd4hep::rec::VolCylinderImpl, dd4hep::rec::VolSurface, and dd4hep::rec::VolSurfaceBase.

◆ id()

virtual long64 dd4hep::rec::ISurface::id ( ) const

pure virtual

The id of this surface - corresponds to DetElement id ( or'ed with the placement ids )

Implemented in dd4hep::rec::Surface, dd4hep::rec::VolSurface, and dd4hep::rec::VolSurfaceBase.

◆ innerMaterial()

virtual const IMaterial& dd4hep::rec::ISurface::innerMaterial ( ) const

pure virtual

Access to the material in opposite direction of the normal.

Implemented in dd4hep::rec::Surface, dd4hep::rec::VolSurface, and dd4hep::rec::VolSurfaceBase.

◆ innerThickness()

virtual double dd4hep::rec::ISurface::innerThickness ( ) const

pure virtual

Thickness of inner material

Implemented in dd4hep::rec::Surface, dd4hep::rec::VolSurface, and dd4hep::rec::VolSurfaceBase.

◆ insideBounds()

virtual bool dd4hep::rec::ISurface::insideBounds	(	const Vector3D &	point,
		double	epsilon = `1.e-4`
	)		const

pure virtual

Checks if the given point lies within the surface.

Implemented in dd4hep::rec::VolSurface, dd4hep::rec::VolSurfaceBase, dd4hep::rec::Surface, and SimpleCylinderImpl.

◆ length_along_u()

virtual double dd4hep::rec::ISurface::length_along_u ( ) const

pure virtual

The length of the surface along direction u at the origin. For 'regular' boundaries, like rectangles, this can be used to speed up the computation of inSideBounds.

Implemented in dd4hep::rec::Surface, dd4hep::rec::VolSurface, and dd4hep::rec::VolSurfaceBase.

◆ length_along_v()

virtual double dd4hep::rec::ISurface::length_along_v ( ) const

pure virtual

The length of the surface along direction v at the origin. For 'regular' boundaries, like rectangles, this can be used to speed up the computation of inSideBounds.

Implemented in dd4hep::rec::Surface, dd4hep::rec::VolSurface, and dd4hep::rec::VolSurfaceBase.
