Function documentation
void ProjectPoint(Float_t& x, Float_t& y, Float_t& z, Float_t d, TEveProjection::EPProc_e proc = kPP_Full)
Project point.
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
