gutz::TransXYManipEvent Class Reference

#include <ManipEvents.h>

Inheritance diagram for gutz::TransXYManipEvent:

gutz::ManipEventBase< Manip > gutz::Counted gutz::TransPlaneManipEvent gutz::TransZManipEvent List of all members.

Detailed Description

Translate XY Manip Event.

Translates the manipulator in X&Y relative to the current view. This is also a base class for other translation events.

Definition at line 74 of file ManipEvents.h.

Event Handlers

bool startEvent (Manip *m, const MouseEvent &me)
 should be called on a Mouse-down event, starts the event

bool handleEvent (Manip *m, const MouseMoveEvent &mme)
 should be called when the mouse moves

void endEvent (Manip *m, const MouseEvent &me)
 called when the event is over, may or may not be on a Mouse-up event

bool tumble (Manip *m)
 repeat last event


Public Types

typedef Manip ManipType
 either a Camera or a Manip (LIGHT??)

vec3f TransXYManipEvent::getDelta (  Manip *  m,
const MouseMoveEvent &  mme
)  const [protected]
 

returns the translaton for this local frame (actually defined in parent's space)

didn't have a picked point

intersect rays with plane at our local position oriented with view direction

compute delta based on the current & last intersections

we DID have a valid pick point

else we didn't have a parent, we just have to use the points...

use ray-plane intersection to compute the delta vector get the ray through the screen points (curr&last) from the eye

therfore the points from the event just need to be translated to our (parents) LOCAL space
