destructor.
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).
