Member Function Documentation

void SoGLUpdateAreaElement::initClass

(

void

)

[static]

This static method initializes static data for the SoGLUpdateAreaElement class.

Reimplemented from SoElement.

SoElement * SoGLUpdateAreaElement::copyMatchInfo

(

void

)

const [virtual]

This function creates a copy of the element that contains enough information to enable the matches() function to work.

Used to help with scenegraph traversal caching operations.

Implements SoElement.

void SoGLUpdateAreaElement::set	(	SoState *const	state,
		const SbVec2f &	origin,
		const SbVec2f &	size
	)			[static]

Sets the update area. This can, for instance, be used when rendering in the front buffer, to only render parts of the scene during a window expose event. origin and size is in normalized window coordinates.

SbBool SoGLUpdateAreaElement::get	(	SoState *const	state,
		SbVec2f &	origin,
		SbVec2f &	size
	)			[static]

Returns the current update area.

set()

SbVec2f SoGLUpdateAreaElement::getDefaultOrigin

(

void

)

[static]

Returns the default update area origin, (0,0).

SbVec2f SoGLUpdateAreaElement::getDefaultSize

(

void

)

[static]

Returns the default update area size, (1,1).
