vtkAbstractTransform and Co. - internal state
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
This is a major feature request for the implementation of vtkAbstractTransform and Co.. In some cases it is very helpful to know if the TemplateTransformPoint() or TemplateTransformInverse() was successful. Currently I see no possibility to get this information. So my proposal is to add some internal state flag in vtkAbstractTransform.
Example: You are using vtkThinPlateSplineTransform with some very scattered points. Then you call TemplateTransformInverse() so the Newton method well be executed, but it fails to converge. At the moment you get an annoying warrning. It would be more usable to get the error state at the runtime, so you can react to this error inside you code.
