Problem: worldToModel reliability vs. own 3d Transform Matrix -> any better Ideas?

[Don Camillo 10]

May sound stupid, but is there (i'm sure there is somewhere) a way to reliably translate a vector from WorldCoordinates Space [x,y,z]

into a objectCoordinates Space beside worldToModel. (While the model may be rotatet in 3 Axes).

So far i found out: worldToModel operates with the positionAGL

wich may be useful in some (wich ever) manners, but not in my Case. I'm not interestet in the relative Position to the next LOD,

i always need to know the relative Position to the Objects "Pivot".

I've done a inverse transformation Matrix script wich does that for me, but i still can't belive that this should be the right way.

Any Ideas to achive my Goal smarter ?:confused:

The intention behind this is to "Paint" a ImpactPosition recorded on my reference, to a "Dummy Object" using the HitPart EventHandler (yes i know the MP issue).

My current excursion into linear algebra resultet into this:

Private ["_targetPos","_hit","_target", "_newDammage","_iPos","_dPos","_tPos"];

_hit = (_this select 0) select 0;

_target = _hit select 0;

_targetPos = getPosASL _target;

_iPos = (_hit select 3);

_dPos = getPosASL dummy;

_tPos = getPosASL _target;

Private ["_veh","_offset","_up","_dir","_uCd","_h00","_h01","_h02","_h03","_h10","_h11","_h12","_h13","_h20","_h21","_h22","_h23","_h30","_h31","_h32","_h33"];

_up = vectorUp _target;

_dir = vectorDir _target;

_uCd = [_up,_dir] call bis_fnc_crossProduct;

_iPos set [3,1];

_dPos set [3,1];
