ViewPortFilter Class Reference

#include <viewport.h>

Class Description

ViewPortFilters are post-processes that are applied to the rendered scene before display.

Mudbox first renders the meshes in the scene, then goes through its list of ViewPortFilters. Any filters with visibility turned on are applied to the resulting image, yielding the new image that is displayed. This base class ViewPortFilter does nothing; you must derive new filters from it.

Member Typedef Documentation

The RequirementValue typedef is used to tell Mudbox what information needs to be calculated at render time so that this ViewPortFilter can work properly.

The elements in this list can be combined with a bitwise or (|) operator. This is used in the Requirements method.

Member Function Documentation

virtual QString StringID ( const ClassDesc pClass = 0) const
virtual

Returns the string id of the viewport filter. It's the same to string id of its class.

Reimplemented from Node.

virtual QString DisplayName ( void  ) const
virtual

Returns the display name of the viewport filter. It's the same to display name of its class.

Reimplemented from Node.

virtual void Initialize ( void  )
virtual

This is called after construction to initialize internal variables.

Reimplemented from Node.

virtual RequirementValue Requirement ( void  ) const
virtual

Returns a value that indicates what information is required by the ViewPortFilter.

When you create your own ViewPortFilter, you must override this method. Mudbox only calculates things like depth maps or normal maps when requested, so you must figure out what information is needed as input to your viewport filter, and have this function return the appropriate flags.

virtual void Process ( ViewPortState sState)
virtual

Process the Mudbox view through the ViewPortFilter.

This method does the actual work of filtering the viewport. Derived ViewPortFilters must override it. It takes the information provided in the ViewPortState that is passed in, and puts the resulting (filtered) image in the m_pColor texture of that object. This method must be overridden by derived classes.

Parameters
[in,out]sStateThe textures used by this filter, and the result
virtual float Transparency ( void  ) const
virtual

This method is not used in ViewPortFilters.

Reimplemented from Layer.

virtual void SetTransparency ( float  fTransparency)
virtual

This method is not used in ViewPortFilters.

Reimplemented from Layer.

virtual Layer* Children ( void  ) const
virtual

This method is not used in ViewPortFilters.

Reimplemented from Layer.

virtual Layer* Next ( void  ) const
virtual

This method is not used in ViewPortFilters.

Reimplemented from Layer.

virtual Layer* Prev ( void  ) const
virtual

This method is not used in ViewPortFilters.

Reimplemented from Layer.

virtual class LayerContainer* Container ( void  ) const
virtual

This method is not used in ViewPortFilters.

Reimplemented from Layer.

void SetVisible ( bool  bVisible)
virtual

Turns the ViewPortFilter on and off.

Parameters
[in]bVisibleSet this true to make the filter visible, and false to hide it.

Reimplemented from TreeNode.

virtual void LockCalibration ( bool  bLock)
virtual

This method locks any calibration the ViewPortFilter does.

Some kinds of ViewPortFilters do a calibration step as part of the process. For example, all the values produced may be normalized to the range of values currently displayed. This can be a problem when you need to generate multiple images where the calibration must be the same (say, to make a large tiled image, or an animation). Locking calibration tells the ViewPortFilter to leave its calibration values at the current level, rather than recalculating per-frame.

Derived ViewPortFilters probably do not need to override this method, but they should pay attention to the flag. If you do need to override the method, ensure the derived method calls the base method so that the flag will be set properly.

Parameters
[in]bLockSet this true to lock calibration, and false to unlock it
bool CalibrationLocked ( void  )

Returns true if the ViewPortFilter calibration is locked.
