The function "AIS_InteractiveContext::DeviationAngle" returns allways the same value:
//function : DeviationAngle
//purpose : Gets deviationAngle

Standard_Real AIS_InteractiveContext::DeviationAngle() const
return PI/180.0e0 ;
// return myDefaultDrawer->DeviationAngle();
Is this a bug or something else ?

DeviationAngle, HRLAngle,DeviationCoefficient, HLRDeviationCoefficient by ASI_InteractiveContex / AIS_Shape ?
This parameters have big influence over quality / efficient...

OCCT 6.5.2 still used this code and always returns a constant value for the deviation angle. Why?

Could this be clarified?

Thank you!
