[OpendTect_Developers] UTM to InlCrl

[David d'Angelo]

Hi folks,

just in case anybody is interested:
I added a the function (to Scene):
const mVisTrans* getInlCrlScaleTransform() const;
to get the scaleTransform. You can now use this function to convert utm 
to inlcrl coordinates:

Coord3 static utm2inlCrl(const Coord3& utm, const visSurvey::Scene* scene) {
         const mVisTrans* ic2disp = scene->getInlCrl2DisplayTransform();
         const mVisTrans* icscale = scene->getInlCrlScaleTransform();
         const mVisTrans* utm2disp = scene->getUTM2DisplayTransform();

         Coord3 disp;
         utm2disp->transform(utm,disp);
         Coord3 ic;
         ic2disp->transformBack(disp,ic);
         icscale->transformBack(ic,ic);

         return ic;
     }

Would you mind adding this function to the OD trunk?

Cheers,
David
