At first please exciuse my english is weak;) I have large problem with reset transform TrackBallDecorator because i cant do it. Long time ago someone on this forum try the same. He advise to reset private variable _previousPosition2D in oryginal dll library
but I do it and it didn't work. I reset also _previousePosition3D, _scale, _rotation and nothing. Since i reset _transform this couse TrackBallDecorator stuck. I have no idea what to do. I've tracked all lines in TrackBallDecorator class but i invent nothing.
I need to reset transform because i want to draw something else on viewport3d from beginning in one application time. Please for any help.
