Detailed Description

VSG extension Class for stereo management.

This class defines a strategy of stereo management. Using a subclass of SoBaseStereo allows an SoWinViewer object to use a stereoscopic rendering mode.

Note: because of internal dependant calls between stereo classes and Open Inventor viewer classes, SoStereoViewer and SoBaseStereo (and inheriting classes) cannot be used without using SoWinViewer/SoXtViewer/SoQtViewer inheriting classes.

Enumerator
NO_STEREO_VIEW 

Monoscopic viewing.

Each view displayed in a half screen.

RAW_STEREO 

Two views superimposed on a single image.

OPENGL_STEREO 

Ditto.

ANAGLYPH_STEREO 

Each view is displayed through a color filter.

ANAGLYPH 

Ditto.

Constructor & Destructor Documentation

◆ SoBaseStereo()

SoBaseStereo::SoBaseStereo ( SoStereoViewer stereoViewer = NULL,
SoGuiViewer guiViewer = NULL 
)

Constructor.

◆ ~SoBaseStereo()

virtual SoBaseStereo::~SoBaseStereo ( )
virtual

Destructor.

The destructor calls clearStereo().

Member Function Documentation

◆ canClearBeforeRender()

virtual SbBool SoBaseStereo::canClearBeforeRender ( ) const
virtual

Queries ability to clear before rendering.

This allows a subclass to forbid the color buffer from being cleared before any rendering. Typically, this takes place after rendering the first view. Then, if canClearBeforeRender() returns FALSE, the color buffer can keep previous modifications, such as for the stencil buffer, etc.

◆ clearStereo()

virtual void SoBaseStereo::clearStereo ( )
virtual

A stereo view type may need to restore a state when it is no longer used by a stereo viewer.

◆ getStereoViewer()

SoStereoViewer * SoBaseStereo::getStereoViewer ( )
inline

Queries the stereo viewer.

Definition at line 119 of file SoBaseStereo.h.

◆ getStereoViewType()

virtual StereoViewType SoBaseStereo::getStereoViewType ( )
pure virtual

Queries the stereo view type.

Implemented in SoAnaglyphStereo, SoHalfScreenStereo, SoInterlacedStereo, SoNoStereoView, SoPassiveStereo, and SoRawStereo.

◆ isStereoViewReversed()

virtual SbBool SoBaseStereo::isStereoViewReversed ( ) const
virtual

Queries stereo reversal.

◆ renderStereoView()

virtual void SoBaseStereo::renderStereoView ( )
virtual

Renders the stereo view.

You can use the SoNoStereoView subclass to render the view without any stereo effect.

Reimplemented in SoHalfScreenStereo, SoNoStereoView, and SoPassiveStereo.

◆ requireHardware()

virtual SbBool SoBaseStereo::requireHardware ( )
inlinevirtual

Returns true or false depending on the type of stereo buffering.

Reimplemented in SoRawStereo.

Definition at line 155 of file SoBaseStereo.h.

◆ reverseStereoView()

virtual void SoBaseStereo::reverseStereoView ( SbBool  reverse)
virtual

Sets stereo reversal.

The left view becomes the right view, and the right view becomes the left view.

◆ setStereoElement()

void SoBaseStereo::setStereoElement ( SoSceneManager ,
SoCamera::StereoMode  stereoMode 
)

Apply stereo parameters to the passed SoSceneManager.

◆ setStereoViewer()

void SoBaseStereo::setStereoViewer ( SoStereoViewer viewer = NULL)
inline

Sets the stereo viewer.
