Member Enumeration Documentation

enum RedrawType

This type controls the behaviour of the Redraw function, used as a parameter there.

Enumerator:
eFull 
eArea 

Schedule a full redraw of the 3d viewport later, ViewPort::Redraw returns immediately when this parameter is used.

eOverlayOnly 

Schedule a redraw of the 3d viewport for the specified area only, ViewPort::Redraw returns immediately when this parameter is used.

Redraws the overlay part of the viewport right away. The 3d content is not redrawn.

Constructor & Destructor Documentation

ViewPort ( void  ) [protected]

Do not use the constructor directly.

It is unlikely that you would ever create your own scene in a plug-in. If you do need to, you should not call the constructor directly. Instead, use CreateInstances, like this:

        Viewport *myNewScene = CreateInstance<Viewport>();  

Member Function Documentation

virtual unsigned int FilterCount ( void  ) const [virtual]

Returns the number of ViewPortFilters associated with this ViewPort.

virtual ViewPortFilter* Filter ( unsigned int  iIndex ) const [virtual]

Returns a pointer to a ViewPortFilter associated with this ViewPort.

Parameters:
[in] iIndex index of the ViewPortFilter to be returned
virtual void AddFilter ( ViewPortFilter pFilter ) [virtual]

Associates a ViewPortFilter with this ViewPort.

Parameters:
[in] pFilter a pointer to the ViewPortFilter to be added
virtual void RemoveFilter ( unsigned int  iIndex ) [virtual]

Removes a ViewPortFilter that was associated with this ViewPort. The filter is not deleted.

Parameters:
[in] iIndex index of the ViewPortFilter to be removed
void LockFilterCalibration ( bool  bLocked )

Locks/unlocks the calibration of all viewport filters associated with this ViewPort. (See ViewPortFilter::LockCalibration())

Parameters:
[in] bLocked Set this true to lock calibration, and false to unlock it
virtual void SaveScreenshot ( const QString &  sFileName ) const [virtual]

Saves a snapshot of the current viewport to the given image file name.

The file type will be determined by the extension of the file name (eg .png, .bmp, .tif). See also Kernel()->RenderScene() for a more flexible method.

Parameters:
[in] sFileName Name of the image file where the screenshot should be saved
virtual int Width ( void  ) [virtual]

Returns the width of the ViewPort in pixels.

virtual int Height ( void  ) [virtual]

Returns the height of the ViewPort in pixels.

class ImagePlaneInterface* ActiveImagePlane ( )

Returns the current image plane.

virtual float CursorXPosition ( void  ) const [virtual]

Returns the current cursor horizontal position inside the viewport in the 0-1 range.

virtual float CursorYPosition ( void  ) const [virtual]

Returns the current cursor vertical position inside the viewport in the 0-1 range.

const SurfacePoint* CursorSurfacePoint ( bool  bMirrored = false ) const

Returns the surface point which is under the cursor.

Parameters:
[in] bMirrored a bool to determine whether getting the mirrored surface point.
