Detailed Description

Defines an OpenGL graphics configuration template.

An OpenGL graphics configuration template is a set of graphics preferences used to choose the best OpenGL graphics configuration (SoGLGraphicConfig) available on an OpenGL graphics device (SoGLGraphicDevice).

There are many different criteria: 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. Every criterion is required, or forbidden, or preferred. The preferred criterion can be extended to an integer weight: SoGraphicConfigTemplate::PREFERRED (equal to 1), 2, 3, 4, 10, 100, 1000, and so forth. The sum of all weights determines if one graphics configuration is better than another.

The default values are:

Double buffer is REQUIRED;
Stereo buffer is FORBIDDEN;
Accelerated OpenGL is REQUIRED;
Depth buffer is REQUIRED; its size is greater than 0;
Non-indexed color is REQUIRED; its R/G/B/A sizes are greater than 0;
Indexed color is FORBIDDEN;
Accumulation buffer is PREFERRED (weight 1); its R/G/B/A sizes are greater than 0;
Stencil buffer is PREFERRED(weight 1); its size is greater than 0;
Full-scene antialiasing is FORBIDDEN.

Implements SoGraphicConfigTemplate.

void SoGLGraphicConfigTemplate::setAccelerated ( SoGraphicConfigTemplate::Preference pref )

Sets the graphics acceleration preference.

void SoGLGraphicConfigTemplate::setAccum	(	SoGraphicConfigTemplate::Preference	pref,
		int	minRedBits = `0`,
		int	minGreenBits = `0`,
		int	minBlueBits = `0`,
		int	minAlphaBits = `0`,
		int	maxRedBits = `INT_MAX`,
		int	maxGreenBits = `INT_MAX`,
		int	maxBlueBits = `INT_MAX`,
		int	maxAlphaBits = `INT_MAX`
	)

Sets the accumulation preferences.

min(red/green/blue/alpha)Bits and max(red/green/blue/alpha)Bits are the minimum and maximum required sizes. The required size must be greater than or equal to min(red/green/blue/alpha)Bits, and less than or equal to max(red/green/blue/alpha)Bits. The maximum size is always preferred. If pref is FORBIDDEN, the min/max values are ignored.

void SoGLGraphicConfigTemplate::setDepth	(	SoGraphicConfigTemplate::Preference	pref,
		int	minBits = `0`,
		int	maxBits = `INT_MAX`
	)

Sets the depth buffer preferences.

minBits and maxBits are the minimum and maximum required sizes. The required size must be greater than or equal to minBits, and less than or equal to maxBits. The maximum size is always preferred. If pref is FORBIDDEN, the min/max values are ignored.

void SoGLGraphicConfigTemplate::setDoubleBuffer ( SoGraphicConfigTemplate::Preference pref )

Sets the double buffer mode preference.

void SoGLGraphicConfigTemplate::setFloatRGBAColor	(	SoGraphicConfigTemplate::Preference	pref,
		int	minFloatRedBits = `15`,
		int	minFloatGreenBits = `15`,
		int	minFloatBlueBits = `15`,
		int	minFloatAlphaBits = `15`,
		int	maxFloatRedBits = `16`,
		int	maxFloatGreenBits = `16`,
		int	maxFloatBlueBits = `16`,
		int	maxFloatAlphaBits = `16`
	)

Sets the float color preferences.

REQUIRED means RGBA mode and FORBIDDEN means indexed color mode. min(red/green/blue/alpha)Bits and max(red/green/blue/alpha)Bits are the minimum and maximum required sizes. The required size must be greater than or equal to the min(red/green/blue/alpha)Bits, and less than or equal to max(red/green/blue/alpha)Bits. The maximum size is always preferred. If pref is FORBIDDEN, the min/max values are ignored.

void SoGLGraphicConfigTemplate::setFullSceneAntialiasing	(	SoGraphicConfigTemplate::Preference	pref,
		int	minFsaaBits = `0`,
		int	maxFsaaBits = `INT_MAX`
	)

Sets the full-scene antialiasing preferences.

Full-scene anti-aliasing by supersampling usually means that each full frame is rendered at double (2x), quadruple (4x), ..., the display resolution, and then down-sampled to match the display resolution. So a 2x FSAA would render four supersampled pixels for each single pixel of each frame. minFsaaBits and maxFsaaBits are integer values specifying the minimum and maximum required number of samples to use during antialiasing computation. The required number of samples must be greater than or equal to minFsaaBits, and less than or equal to maxFsaaBits. The maximum number of samples is always preferred. If pref is FORBIDDEN, the min/max values are ignored.

void SoGLGraphicConfigTemplate::setRGBAColor	(	SoGraphicConfigTemplate::Preference	pref,
		int	minRedBits = `0`,
		int	minGreenBits = `0`,
		int	minBlueBits = `0`,
		int	minAlphaBits = `0`,
		int	maxRedBits = `INT_MAX`,
		int	maxGreenBits = `INT_MAX`,
		int	maxBlueBits = `INT_MAX`,
		int	maxAlphaBits = `INT_MAX`
	)

Sets the color preferences.

REQUIRED means RGBA mode and FORBIDDEN means indexed color mode. min(red/green/blue/alpha)Bits and max(red/green/blue/alpha)Bits are the minimum and maximum required sizes. The required size must be greater than or equal to the min(red/green/blue/alpha)Bits, and less than or equal to max(red/green/blue/alpha)Bits. The maximum size is always preferred. If pref is FORBIDDEN, the min/max values are ignored.

void SoGLGraphicConfigTemplate::setStencil	(	SoGraphicConfigTemplate::Preference	pref,
		int	minBits = `0`,
		int	maxBits = `INT_MAX`
	)

Sets the stencil preferences.

REQUIRED means indexed color mode and FORBIDDEN means RGBA mode. minBits and maxBits are the minimum and maximum required size. The required size must be greater than or equal to minBits, and less than or equal to maxBits. The maximum size is always preferred. If pref is FORBIDDEN, the minBits and maxBits values are ignored.

void SoGLGraphicConfigTemplate::setStereoBuffer ( SoGraphicConfigTemplate::Preference pref )

Sets the stereo buffer mode preference.
