Detailed Description

Represents an OpenGL graphics configuration for UNIX/Linux (Xt-based) systems.

This class is a representation of an XVisualInfo struct or a GLXFBConfig. Compared to its parent class, this class adds a method to query the system-dependent XVisualInfo or GLXFBConfig struct.

Member Function Documentation

getAccum()

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

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.

Implements SoGLGraphicConfig.

getDepth()

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

virtual

Returns the Z-buffer depth.

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

Implements SoGLGraphicConfig.

getFBConfig()

GLXFBConfig * SoXtGLGraphicConfig::getFBConfig

(

)

Returns the Frame Buffer Configuration.

getFloatRGBAColor()

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

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.

Implements SoGLGraphicConfig.

getFullSceneAntialiasing()

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

virtual

Returns the availability of the hardware full-scene antialiasing feature.

Parameters

bits	returns the number of samples used in the antialiasing algorithm.

Implements SoGLGraphicConfig.

getRGBAColor()

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

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.

Implements SoGLGraphicConfig.

getStencil()

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

virtual

Returns the stencil buffer depth.

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

Implements SoGLGraphicConfig.

getXVisualInfo()

SbGlContextHelper::VisualInfo SoXtGLGraphicConfig::getXVisualInfo

(

)

Returns the X visual information.

isAccelerated()

virtual SbBool SoXtGLGraphicConfig::isAccelerated ( ) const

virtual

Returns TRUE if the OpenGL graphics configuration is accelerated.

Implements SoGLGraphicConfig.

isDoubleBuffer()

virtual SbBool SoXtGLGraphicConfig::isDoubleBuffer ( ) const

virtual

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

Implements SoGLGraphicConfig.

isStereoBuffer()

virtual SbBool SoXtGLGraphicConfig::isStereoBuffer ( ) const

virtual

Returns TRUE if stereo buffer mode is supported.

Implements SoGLGraphicConfig.
