- void SoGLUpdateAreaElement::initClass (void) [static]This static method initializes static data for the SoGLUpdateAreaElement class.
- 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.
- 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.
- 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).

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.

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).
