Definition at line 134 of file TEveProjections.h.

◆ AddPreScaleEntry()

void TEveProjection::AddPreScaleEntry ( Int_t coord,
Float_t value,
Float_t scale )
inherited

Add new scaling range for given coordinate.

Arguments:

  • coord 0 ~ x, 1 ~ y, 2 ~ z
  • value value of input coordinate from which to apply this scale;
  • scale the scale to apply from value onwards.

NOTE: If pre-scaling is combined with center-displaced then the scale of the central region should be 1. This limitation can be removed but will cost CPU.

◆ BisectBreakPoint() [1/2]

void TEveProjection::BisectBreakPoint ( TEveVector & vL,
TEveVector & vR,
Bool_t project_result = kFALSE,
Float_t depth = 0 )
virtualinherited

Find break-point on both sides of the discontinuity.

If project_result is true, the resulting break points will be projected with given depth value.

◆ BisectBreakPoint() [2/2]

void TEveProjection::BisectBreakPoint ( TEveVector & vL,
TEveVector & vR,

virtualinherited

They still need to be projected after the call. This is an obsolete version of the method that required manual specification of precision – this lead to (infrequent) infinite loops.

void TEveProjection::ChangePreScaleEntry ( Int_t coord,
Int_t entry,

NOTE: If the first entry you created used other value than 0, one entry (covering range from 0 to this value) was created automatically.
