Detailed Description

VSG extension Class for interlaced stereo support.

This class implements the interlaced stereo type. Using the interlaced mode, the stereo effect is achieved using special devices (projectors,...) that translate an interlaced image into a stereoscopic view. Alternating scan lines display images for the left and right eyes.

The interlaced mode can work in two modes: fast or best. This is simply a matter of quality. Due to the interlacing, lines close to horizontal can appear as dotted lines. In best mode, those parts of the model are drawn as if they were thicker. By default, the mode is fast.

Member Function Documentation

◆ enableGreenShift()

void SoInterlacedStereo::enableGreenShift ( SbBool  enable)

Enable image adjustment specific to Sharp LCD displays.

Definition at line 115 of file SoInterlacedStereo.h.

◆ getInterlacedMode()

InterlacedMode SoInterlacedStereo::getInterlacedMode ( ) const

Queries interlaced mode.

Definition at line 81 of file SoInterlacedStereo.h.

◆ getStereoViewType()

virtual StereoViewType SoInterlacedStereo::getStereoViewType ( )

Always returns SoBaseStereo::INTERLACED_STEREO.

Implements SoBaseStereo.

Definition at line 110 of file SoInterlacedStereo.h.

◆ isFastInterlacing()

SbBool SoInterlacedStereo::isFastInterlacing ( ) const

Queries fast interlacing mode.

Definition at line 105 of file SoInterlacedStereo.h.

◆ isGreenShiftEnabled()

SbBool SoInterlacedStereo::isGreenShiftEnabled ( ) const

Query green shift setting.

Definition at line 120 of file SoInterlacedStereo.h.

◆ isScreenInterlacing()

SbBool SoInterlacedStereo::isScreenInterlacing ( ) const

Queries screen interlacing.

Definition at line 95 of file SoInterlacedStereo.h.

◆ setFastInterlacing()

void SoInterlacedStereo::setFastInterlacing ( SbBool  fast = TRUE)

Sets fast interlacing mode.

Default is TRUE.

Definition at line 100 of file SoInterlacedStereo.h.

◆ setInterlacedMode()

void SoInterlacedStereo::setInterlacedMode ( InterlacedMode  mode)

Sets interlaced mode.

Default is HORIZONTAL.

Definition at line 76 of file SoInterlacedStereo.h.

◆ setScreenInterlacing()

void SoInterlacedStereo::setScreenInterlacing ( SbBool  screen)

Sets screen interlacing.

If screen is TRUE (default), the line interlacing is done according to the screen (if the window is moving, the first line might be either an even or an odd line). Otherwise, do the interlacing according to the window itself (first line is always even).
