Detailed Description

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.

Member Enumeration Documentation

enum SoBaseStereo::StereoViewType

Stereo view types.

Enumerator:

NO_STEREO_VIEW	Monoscopic viewing.
INTERLACED_STEREO	Two views interlaced in a single image.
HALF_SCREEN_STEREO	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.
PASSIVE_STEREO

Constructor & Destructor Documentation

SoBaseStereo::SoBaseStereo ( SoStereoViewer * stereoViewer = NULL )

Constructor.

virtual SoBaseStereo::~SoBaseStereo ( ) [virtual]

Destructor.

The destructor calls clearStereo().

Member Function Documentation

virtual SbBool SoBaseStereo::canClearBeforeRender ( ) [pure 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.

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

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.

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

SoStereoViewer* SoBaseStereo::getStereoViewer ( ) [inline]

Queries the stereo viewer.

virtual StereoViewType SoBaseStereo::getStereoViewType ( ) [pure virtual]

Queries the stereo view type.

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

virtual SbBool SoBaseStereo::isStereoViewReversed ( ) [pure virtual]

Queries stereo reversal.

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