Detailed Description

provides event-driven interface to the rendering window.

vtkInteractorStyleCAD implements the "trackball" style of interaction. That is, holding down the motion keys and then moving the mouse causes motion in proportion to the amount of motion.

The event bindings for this class include the following:

• Keypress F1 + mouse motion: pan camera.
• Keypress F2 + mouse motion: zoom camera.
• Keypress F3 + mouse motion: rotate camera around its focal point.
• Button 1: perform a pick operation. This object has an internal instance of vtkCellPicker that it uses to pick. When it successfully picks a cell, it highlights it with PickColor. Automatic highlighting can be controlled with CellHighlight ivar.
• Keypress 'r': reset the camera view along the current view direction. Centers the actors and moves the camera so that all actors are visible.
• Keypress 's': modify the representation of all actors so that they are surfaces.
• Keypress 'w': modify the representation of all actors so that they are wireframe.
• Keypress 'd': modify the representation of all actors so that they are points.

Member Function Documentation

vtkCellPicker * GetCellPicker ( ) [virtual]

Get this objects cell picker.

int GetChar ( ) [virtual]

Get the character for a Char event.

vtkGeometryFilter * GetHighlightGeomFilter ( ) [virtual]

Get this objects geometry filter (used for highlighting).

char * GetKeySym ( ) [virtual]

Get the KeySym (in the same format as Tk KeySyms) for a KeyPress or KeyRelease method.

int * GetLastPos ( ) [virtual]

Get the most recent mouse position during mouse motion. In your user interaction method, you must use this to track the mouse movement. Do not use GetEventPosition(), which records the last position where a mouse button was pressed.

int * GetOldPos ( ) [virtual]

Get the previous mouse position during mouse motion, or after a key press. This can be used to calculate the relative displacement of the mouse.

int GetShiftKey ( ) [virtual]

Test whether modifiers were held down when mouse button or key was pressed

void HighlightGeometry ( vtkActor * a, vtkDataSet * ds, int minId, int maxId )

Highlight dataset cells with ids between minId and maxId (inclusive). Highlighting is done by changing color of the cells (color is controled by PickColor ivar). If cells have scalars, scalar values are used for coloring.

vtkInteractorStyleCAD * New ( ) [static]

Instantiate object with cell highlighting on. Reimplemented from vtkInteractorStyle.

void SetCellHighlight ( int ) [virtual]

Enable/Disable highlighting of picked cell.

void SetUserInteractionMethod ( void(* f)(void *), void * arg )

Set a method that will be called every time the mouse is moved while UserInteraction mode is on. You can use GetLastPos() to determine the position of the cursor in display coordinates, and GetOldPos() to determine the previous position.

void StartUserInteraction ( )

Start/Stop user interaction mode. While the UserInteraction mode is set, the UserInteraction method will be called every time the mouse moves. You must not call these methods before you have Initialized the vtkRenderWindowInteractor.
