From Jan Perciva with changes from Robert Osfield, "I am submitting improved osgGA camera manipulators. Changes: - new mouse wheel zoom/movement/center functionality - ability to fix vertical axis (important for CAD) - possibility to specify values as absolute values or relative to model size - kind of backward compatibility by flags passed to constructor - and much more - restructuring classes to use kind of hierarchy and standard way of event processing (handle methods). This way, there is much more code reusability and it is more easy to develop new kinds of manipulators. Briefly, the new architecture keeps MatrixManipulator as base abstract class. StandardManipulator is the feature-rich standard manipulator with two main descendant classes: OrbitManipulator and FirstPersonManipulator. OrbitManipulator is base class for all trackball style manipulators, based on center, rotation and distance from center. FirstPersonManipulator is base for walk or fly style manipulators, using position and rotation for camera manipulation. " Changes by Robert: Replaced osg::Vec3 by osg::Vec3d, introduced DEFAULT_SETTINGS enum and usage. Added frame time member variables in prep for improving throw animation when vysync is off.

From Mikkel Gjøl, addition of paramter set/get methods to osgGA::*Manipulators, change of ' ' to GUIEventAdapter::KEY_Space, fix to url in Matrix_implementation.cpp. Syntax fixes by Robert Osfield to above submission fix inconsistencies with normal OSG coding style.

From Lee Bulter, "I noticed that when "throwing" things the rate of motion once thrown was dependent on the complexity of the geometry. For complex scenes this meant that it looked like you were "throwing" the display into molasses. For simple geometry things get over-excited once thrown. The fix is to factor in the frame rendering time to the caluclated motion. I've implemented this for rotation and panning. Now when things are thrown they maintain a rate very close to what was happening when the mouse button was released."
