AIS_Manipulator class has been created to provide interactive services for manipulating with mouse local transformations of other interactive objects. The class features three kinds of transformation modes for attached objects: - translation of through axis - scaling within axis - rotation around axis For more details please have a look at description of the class in reference manual or in header file. The patch includes DRAW test workbench for evaluating the AIS_Manipulator features. Clang warning (override)
