Detailed Description

interactive manipulation of the camera.

Date:

2001/10/11 13:38:12

Revision:

1.7

vtkInteractorStyleTrackballCamera allows the user to interactively manipulate (rotate, pan, etc.) the camera, the viewpoint of the scene. The position of the mouse relative to the center of the scene determines the speed at which the camera moves. When the mouse stops moving, so does the camera. For a 3-button mouse, the left button is for rotation, the right button for zooming, the middle button for panning, and ctrl + left button for spinning. (With fewer mouse buttons, ctrl + shift + left button is for zooming, and shift + left button is for panning.)

Member Function Documentation

vtkInteractorStyleTrackballCamera* vtkInteractorStyleTrackballCamera::New (    )  [static]

This class must be supplied with a vtkRenderWindowInteractor wrapper or parent. This class should not normally be instantiated by application programmers. Reimplemented from vtkInteractorStyle.

virtual const char* vtkInteractorStyleTrackballCamera::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkInteractorStyle.

int vtkInteractorStyleTrackballCamera::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkInteractorStyle.

virtual int vtkInteractorStyleTrackballCamera::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkInteractorStyle.

vtkInteractorStyleTrackballCamera* vtkInteractorStyleTrackballCamera::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::OnMouseMove (  int    ctrl, int    shift, int    x, int    y )  [virtual]

Event bindings controlling the effects of pressing mouse buttons or moving the mouse. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::OnLeftButtonDown (  int    ctrl, int    shift, int    x, int    y )  [virtual]

Event bindings controlling the effects of pressing mouse buttons or moving the mouse. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::OnLeftButtonUp (  int    ctrl, int    shift, int    x, int    y )  [virtual]

Event bindings controlling the effects of pressing mouse buttons or moving the mouse. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::OnMiddleButtonDown (  int    ctrl, int    shift, int    x, int    y )  [virtual]

Event bindings controlling the effects of pressing mouse buttons or moving the mouse. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::OnMiddleButtonUp (  int    ctrl, int    shift, int    x, int    y )  [virtual]

Event bindings controlling the effects of pressing mouse buttons or moving the mouse. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::OnRightButtonDown (  int    ctrl, int    shift, int    x, int    y )  [virtual]

Event bindings controlling the effects of pressing mouse buttons or moving the mouse. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::OnRightButtonUp (  int    ctrl, int    shift, int    x, int    y )  [virtual]

Event bindings controlling the effects of pressing mouse buttons or moving the mouse. Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackballCamera::RotateXY (  int    dx, int    dy )  [protected]

void vtkInteractorStyleTrackballCamera::PanXY (  int    x, int    y, int    oldX, int    oldY )  [protected]

void vtkInteractorStyleTrackballCamera::DollyXY (  int    dx, int    dy )  [protected]

void vtkInteractorStyleTrackballCamera::SpinXY (  int    dx, int    dy, int    oldX, int    oldY )  [protected]
