Definition at line 133 of file TEveProjections.h.
Add new scaling range for given coordinate.
Arguments:
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.

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.

Find break-point on both sides of the discontinuity.
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.

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