Detailed Description

Defines an OpenGL graphics configuration.

This class is an abstraction of an OpenGL graphics configuration (analogous to a pixel format on Microsoft Windows or a visual on X). It provides methods to inquire what the OpenGL graphics configuration supports: double/single buffer, raw stereo, OpenGL acceleration, Z-buffer depth size, RGBA/indexed colors and size, accumulation buffer and size, stencil buffer and size, etc.

Member Function Documentation

getAccum()

virtual void SoGLGraphicConfig::getAccum ( int &  redBits, int &  greenBits, int &  blueBits, int &  alphaBits  ) const

pure virtual

Returns the accumulation buffer depth (red, green, blue, and alpha).

If (red/green/blue/alpha)Bits are equal to 0, then the OpenGL graphics configuration has no accumulation buffer.

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.

getDepth()

virtual void SoGLGraphicConfig::getDepth ( int &  bits ) const

pure virtual

Returns the Z-buffer depth.

If 0 is returned, then there is no Z-buffer.

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.

getFloatRGBAColor()

virtual void SoGLGraphicConfig::getFloatRGBAColor ( int &  redBits, int &  greenBits, int &  blueBits, int &  alphaBits  ) const

pure virtual

Returns the floating point color depth (red, green, blue, and alpha).

If (red/green/blue/alpha)Bits are equal to 0, then the OpenGL graphics configuration does not support floating point RGBA mode.

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.

getFullSceneAntialiasing()

virtual SbBool SoGLGraphicConfig::getFullSceneAntialiasing ( int &  bits ) const

pure virtual

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.

getRGBAColor()

virtual void SoGLGraphicConfig::getRGBAColor ( int &  redBits, int &  greenBits, int &  blueBits, int &  alphaBits  ) const

pure virtual

Returns the color depth (red, green, blue, and alpha).

If (red/green/blue/alpha)Bits are equal to 0, then the OpenGL graphics configuration does not support RGBA mode.

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.

getStencil()

virtual void SoGLGraphicConfig::getStencil ( int &  bits ) const

pure virtual

Returns the stencil buffer depth.

If 0 is returned, then the OpenGL graphics configuration has no stencil buffer.

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.

isAccelerated()

virtual SbBool SoGLGraphicConfig::isAccelerated ( ) const

pure virtual

Returns TRUE if the OpenGL graphics configuration is accelerated.

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.

isDoubleBuffer()

virtual SbBool SoGLGraphicConfig::isDoubleBuffer ( ) const

pure virtual

Returns TRUE if double-buffer mode is enabled, else FALSE (single-buffer mode).

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.

isStereoBuffer()

virtual SbBool SoGLGraphicConfig::isStereoBuffer ( ) const

pure virtual

Returns TRUE if stereo buffer mode is supported.

Implemented in SoWinGLGraphicConfig, and SoXtGLGraphicConfig.
