Function documentation

TEveRhoZProjection()

 Constructor.

void ProjectPoint(Float_t& x, Float_t& y, Float_t& z, Float_t d, TEveProjection::EPProc_e proc = kPP_Full)

 Project point.

void SetCenter(TEveVector& v)

 Set center of distortion (virtual method).

void SetDirectionalVector(Int_t screenAxis, TEveVector& vec)

 Get direction in the unprojected space for axis index in the
 projected space.
 This is virtual method from base-class TEveProjection.

Bool_t AcceptSegment(TEveVector& v1, TEveVector& v2, Float_t tolerance) const

 Check if segment of two projected points is valid.

 Move slightly one of the points if by shifting it by no more than
 tolearance the segment can become acceptable.

Int_t SubSpaceId(const TEveVector& v) const

 Return sub-space id for the point.
 0 - upper half-space
 1 - lowwer half-space

Bool_t IsOnSubSpaceBoundrary(const TEveVector& v) const

 Checks if point is on sub-space boundrary.

Bool_t Is2D() const

Bool_t Is3D() const

Float_t* GetProjectedCenter()

Bool_t HasSeveralSubSpaces() const

{ return kFALSE; }
