Function documentation

TEveRhoZProjection(const TEveRhoZProjection& )
 Constructor.
void ProjectPoint(Float_t& x, Float_t& y, Float_t& z, TEveProjection::EPProc_e proc = kPP_Full)
 Project point.
void SetCenter(TEveVector& center)
 Set center of distortion (virtual method).
void UpdateLimit()

 projected space.
 This is virtual method from base-class TEveProjection.
Bool_t AcceptSegment(TEveVector& v1, TEveVector& v2, Float_t tolerance)
 Check if segment of two projected points is valid.
Float_t* GetProjectedCenter()
{ return fCenter.Arr(); }
TEveRhoZProjection(const TEveRhoZProjection& )
virtual ~TEveRhoZProjection()
{}
