Detailed Description

Position uppdate policy:

mOrgin,mOrginRx,mOrginRy are always uppdated when state is air together with lattice indices

mOrginRx,mOrginRy are not valid if outside lattice

mTrnOrg,mTrnOrgRx,mTrnOrgRy inherits mOrgin when entering fiber/lumen and becomes master. Echoes state to mOrgin on border hit

General trace rules: NOTE: Not yet finnished!!!!

Vars used outside fiber mOrgin, mDir, mTtoHit

Vars used inside fiber

Vars used inside lumen

int RndRay::LeaveFiberTo_x

(

)

Setup ray from passage fiber->? through currently detected intersection Moves to hitpoint

Note:

Allocates new ray-number if passage -> air

Returns:

true on error. May hapen if misses intersection passes out through end caping outside lattice

int RndRay::MoveToNextLatticePoint

(

)

Forwards ray to next precalculated lattice point note Does _NOT_ check that point is calculated!! This point may lie outside ray, calc next to find out...

Returns:

Here is the call graph for this function:

void RndRay::SetNewDir

(

V3< double > &

rNdir

)

Sets new direction. Warning, latice boundaries must be recalculated.

Note:

Also resets the accumulated traveled distance to 0 and any eventual nontaken hit
